Method embodiment
Referring to fig. 1, an embodiment of the present invention provides a method for evaluating electrical parameters of a desulfurization system, including:
step 100, determining a plurality of electrical parameters of the desulfurization system.
The electronics determine a plurality of electrical parameters of the desulfurization system. The electric parameters can be current measuring points and voltage measuring points of all analog quantities and alarm points of all switching quantities on a distributed control system of the desulfurization system. The range of the current measuring point and the voltage measuring point comprises the current and voltage values of a power supply section such as a 6kv section, a 380V PC section, a security section, a public section, a UPS (collectively Uninterruptible Power Supply, translating into a continuous power system), a direct current system, a transformer, a public MCC (collectively motor Control center, translating into a motor control center) and the like. The alarm points of the switching value comprise switch value alarm points such as loop tripping, power supply disappearance, fault alarm and the like.
Specifically, in one embodiment, the plurality of electrical parameters may be electrical parameters of three modules, namely, the #3 unit electrical module, the #4 unit electrical module, and the second-stage utility electrical module of one electrical subsystem of the desulfurization system.
The electrical parameters of the electric module of the #3 unit can comprise a feed line current I of a 6KV desulfurization working transformer of the #3 furnace, a feed line loop current I of a 380V desulfurization working PC section of the #3 furnace, an AB phase voltage Uab of a 380V bus voltage transformer of the #3 furnace, a BC phase voltage Ubc of a 380V bus voltage transformer of the #3 furnace, a CA phase voltage Uca of a 380V bus voltage transformer of the #3 furnace, a feed line voltage Ua of a #3 furnace desulfurization safety MCC, a feed line voltage Ub of a #3 furnace desulfurization safety MCC, a feed line circuit breaker control loop 2 current I of a 380V desulfurization safety section of the #3 furnace, and a feed line breaker control loop 1 current I of a 380V desulfurization safety section of the #3 furnace.
The secondary utility electrical module may include a battery pack loop battery voltage, a UPS system bypass feeder cabinet output voltage, and a dc feeder screen dc bus voltage.
The electric module of the #4 unit can comprise a feed line current I of a #4 furnace 6KV desulfurization working transformer, a feed line loop current I of a #4 furnace 380V desulfurization working PC section, an AB phase voltage Uab of a #4 furnace 380V bus voltage transformer, a BC phase voltage Ubc of a #4 furnace 380V bus voltage transformer, a CA phase voltage Uca of a #4 furnace 380V bus voltage transformer, a feed line voltage Ua of a #4 furnace desulfurization safety MCC, a feed line voltage Ub of a #4 furnace desulfurization safety MCC, a feed line voltage Uc of a #4 furnace desulfurization safety MCC and a feed line breaker control loop 1 current I of a #4 furnace 380V desulfurization safety section.
Step 200, determining an electrical parameter score of each electrical parameter based on each electrical parameter, a preset allowable value range, a preset limit value range and an optimal value corresponding to each electrical parameter; wherein the preset allowable value range, the preset limit value range and the optimal value of the electrical parameter are respectively determined based on the historical value of the electrical parameter, the optimal value is located in the preset allowable value range, and the preset allowable value range is located in the preset limit value range.
Wherein the preset allowable value range, the preset limit value range and the optimal value can be set by combining expert experience and historical values. The preset allowable value range is the allowable fluctuation range of the electrical parameter, and is generally determined according to a historical value, an electrical and electric national standard, an equipment design value and an equipment interlocking start-stop value, and is controlled within a DCS alarm limit range, and meanwhile, an expert experience value is referred to. The preset limit value range is the parameter fault range value, and is generally determined according to a historical value, a design value or a protection trip fixed value; the optimal value is a dynamic expected value under real-time working conditions obtained by establishing a mathematical model through independent variable parameters related to the electrical parameters.
For example, the current value for the desulfurization system may be set as follows: (1) the allowable upper limit threshold of the preset allowable value range is 1.05 times of the historical value, and the allowable lower limit threshold is 0, (2) the limit upper limit threshold is 1.1 times of the historical value, and the limit lower limit threshold is-1; (3) the current value should consider the closing condition of the tie switch of two units, such as the feeder current of a 6KV desulfurization working transformer, the historical value should be the sum of the historical values of the two units, and (4) the limit value of the single feeder current should not exceed the rated current of the switch and the rated current of non-equipment. The historical value may be understood as a historical average.
The voltage value may be set as follows: (1) the allowable upper limit threshold and the allowable lower limit threshold of the allowable value range are preset to be rated value +/-5 percent, and (2) the limit upper limit threshold and the limit lower limit threshold are preset to be rated value +/-10 percent.
It should be noted that the following may be set for the specific equipment values: (1) the allowable upper limit threshold value and the allowable lower limit threshold value of the output voltage of the uninterruptible power system are set to be rated value +/-2%, the allowable upper limit threshold value and the allowable lower limit threshold value of the output frequency of the uninterruptible power system are set to be rated value +/-0.1%, the allowable upper limit threshold value and the allowable lower limit threshold value of the output frequency of the uninterruptible power system are set to be rated value +/-0.5%, and (3) all alarm tripping points in a DCS interface are set to be emergency level 3.
According to the invention, the electric parameter score of each electric parameter is determined based on each electric parameter, the preset allowable value range, the preset limit value range and the optimal value determined by the historical value of each electric parameter, so that a plurality of electric parameters of the desulfurization system are evaluated, the problems that the workload of an on-duty personnel on an operation monitoring panel is high and the efficiency of the operation monitoring panel is low due to the fact that a DCS picture is required to be continuously browsed and the operation experience is adjusted in the past are solved, the workload of the operation monitoring panel is reduced, and the efficiency of the monitoring panel is improved are realized.
In other aspects of the embodiments of the present invention, step 200 of determining an electrical parameter score for each electrical parameter based on each electrical parameter, a preset allowable range, a preset limit range, and an optimal value for each electrical parameter, includes: and determining an electrical parameter score of the electrical parameter based on the electrical parameter, the optimal value, the upper limit threshold, the safety score reference value and the optimization score reference value when the electrical parameter is greater than the optimal value of the electrical parameter and less than the upper limit threshold of the preset allowable value range of the electrical parameter.
The electrical parameter score is determined by the sum of the safety score and the optimization score, wherein the safety score is full of 80 points, the optimization score is full of 20 points, and the total is 100 points. The safety score calculating method comprises the following steps: when the electrical parameter is in the preset allowable value range, the safety score is evaluated according to 80-score full scale, and when the electrical parameter is out of the preset allowable value range, different emergency levels correspond to different safety scores, wherein the emergency level 1, the safety score range is between 60 and 79, the calculation rule is that the actual operation value is between the allowable upper limit threshold and the limit upper limit threshold, or between the limit lower limit threshold and the allowable lower limit threshold, the calculation rule is calculated according to 60 scores, which is equal to or exceeds the preset limit value range. The emergency level is 2, the safety score is in the range of 0-59, the calculation mode is also linear interpolation method scoring, and the calculation is carried out according to 0 points exceeding the preset limit value range. An emergency level of 3 is calculated as 0 points. The optimization score calculating method comprises the following steps: the actual running value of the electrical parameter is in a preset allowable value range, the score is calculated by adopting a linear interpolation method according to the deviation between the actual running value and the optimal value; the actual running value of the electrical parameter is equal to the allowable upper limit threshold, equal to the allowable lower limit threshold or is out of the preset allowable value range, and is not scored.
Specifically, assume that the electrical parameter is the battery pack circuit battery voltage, which is a value of 102. The upper allowable threshold of the battery voltage of the battery pack loop is 105, the lower allowable threshold is 95, the upper limit threshold is 110, the lower limit threshold is 90, the optimal value is 100, and the emergency level is 2. The safety score reference value is 80 and the optimization score reference value is 20.
Then, at this time, the electrical parameter 102 is greater than the optimal value 100 and less than the allowable upper threshold 105 of the preset allowable range, and the electrical parameter score of the battery pack circuit battery voltage is:
[1- (electrical parameter-optimum value)/(allowable upper limit threshold-optimum value) ]×20+80= [1- (102-100)/(105-100) ]×20+80=92.
Wherein the safety is 80, and the optimization score is [1- (electrical parameter-optimal value)/(allowable upper limit threshold-optimal value) ]x20 = [1- (102-100)/(105-100) ]x20.
The electric parameters and equipment of the desulfurization system are displayed with corresponding icons. The electrical parameter score can be displayed green within 80-100, yellow within 60-79 and red below 60 minutes. Therefore, the embodiment of the invention evaluates the electrical parameters of the desulfurization system in real time, gives a quantization score, assists operators to monitor, thereby achieving the purposes of reducing the operation intensity of the operators on duty monitor, reducing the workload of the operators on duty monitor, improving the efficiency of the monitor, improving the predictive diagnosis level of the electrical parameters and realizing less operators on duty.
In other aspects of the embodiments of the present invention, step 200 of determining an electrical parameter score for each electrical parameter based on each electrical parameter, a preset allowable range, a preset limit range, and an optimal value for each electrical parameter, includes: and determining an electrical parameter score of the electrical parameter based on the electrical parameter, the optimal value, the allowable lower threshold, the safety score reference value and the optimization score reference value when the electrical parameter is smaller than the optimal value of the electrical parameter and larger than the allowable lower threshold of the preset allowable value range of the electrical parameter.
Specifically, assume that the electrical parameter is the battery pack circuit battery voltage, which is 98.

The safety score reference value is 80 and the optimization score reference value is 20.
Then, at this time, the electrical parameter 98 is smaller than the optimal value 100 and larger than the allowable lower threshold 95 of the preset allowable range, and the electrical parameter score of the battery pack circuit battery voltage is:
[1- (electrical parameter-optimum value)/(allowable lower limit threshold-optimum value) ]×20+80= [1- (98-100)/(95-100) ]×20+80=92.
Wherein the safety is 80, and the optimization score is [1- (electrical parameter-optimal value)/(allowable lower limit threshold-optimal value) ]x20 = [1- (98-100)/(95-100) ]x20.
The electric parameters and equipment of the desulfurization system are displayed with corresponding icons. The electrical parameter score can be displayed green within 80-100, yellow within 60-79 and red below 60 minutes. Therefore, the embodiment of the invention evaluates the electrical parameters of the desulfurization system in real time, gives a quantization score, assists operators to monitor, thereby achieving the purposes of reducing the operation intensity of the operators on duty monitor, reducing the workload of the operators on duty monitor, improving the efficiency of the monitor, improving the predictive diagnosis level of the electrical parameters and realizing less operators on duty.
In other aspects of the embodiments of the present invention, step 200 of determining an electrical parameter score for each electrical parameter based on each electrical parameter, a preset allowable range, a preset limit range, and an optimal value for each electrical parameter, includes: and determining an electrical parameter score of the electrical parameter based on the electrical parameter, the upper limit threshold, the safety score reference value and the optimization score reference value when the electrical parameter is greater than an upper limit threshold of a preset allowable value range of the electrical parameter and less than a limit upper limit threshold of a preset limit value range of the electrical parameter.
Specifically, assume that the electrical parameter is the battery pack circuit battery voltage, which is 107. The upper allowable threshold of the battery voltage of the battery pack loop is 105, the lower allowable threshold is 95, the upper limit threshold is 110, the lower limit threshold is 90, the optimal value is 100, and the emergency level is 2. The safety score reference value is 59 and the optimization score reference value is 0.
Then, at this time, the electrical parameter 107 is greater than the allowable upper threshold 105 of the preset allowable range and less than the limit upper threshold 110 of the preset limit range, and the electrical parameter score of the battery cell voltage of the battery cell circuit is:
[1- (electrical parameter-upper limit allowable threshold)/(upper limit threshold-upper limit allowable threshold) ] ×59= [1- (107-105)/(110-105) ] ×59=35.4.
Wherein the safety score is [1- (107-105)/(110-105) ]. Times.59, and the optimization score is 0.
It should be noted that the safety scoring reference value and the optimization scoring reference value are obtained based on a scoring mapping relationship, and the scoring mapping relationship includes the safety scoring reference value and the optimization scoring reference value corresponding to different emergency levels of the electrical parameters. In the embodiment of the invention, the general attribute parameter is determined to be the emergency level 1. The determination of possessing the security attribute is emergency level 2. The switching values of equipment accident tripping, protection tripping and the like are represented as important safety attributes, and are determined as emergency level 3. And determining the fault point of the quality judgment point related to the analog quantity as an emergency level 5. In the embodiment of the invention, the emergency level of the current value parameter is set to be 1; the emergency level of the voltage value parameter is set to 2, and the emergency level of the parameters of the UPS system and the direct current system is set to 2.
For example, when the emergency level is 2, the security score reference value and the optimization score reference value are 59 and 0, respectively.
In another embodiment, when the emergency level is 1, the safety score reference value is 60 and 79-60=19, respectively, and the optimization score reference value is 0.
Assume that the electrical parameter is the battery pack circuit battery voltage, which is a value of 107. The allowable upper limit threshold of the battery pack loop battery voltage is 105, the allowable lower limit threshold is 95, the ultimate upper limit threshold is 110, the ultimate lower limit threshold is 90, the optimal value is 100, and when the emergency level is 1, the electrical parameter score of the battery pack loop battery voltage is:
[1- (electrical parameter-allowable upper limit threshold value)/(limit upper limit threshold value-allowable upper limit threshold value) ]× (79-60) +60= [1- (107-105)/(110-105) ]× (79-60) +60=71.4.
The safety score was [1- (electrical parameter-upper limit allowable threshold)/(upper limit allowable threshold) ]× (79-60) +60, and the optimization score was 0.
The electric parameters and equipment of the desulfurization system are displayed with corresponding icons. The electrical parameter score can be displayed green within 80-100, yellow within 60-79 and red below 60 minutes. Therefore, the embodiment of the invention evaluates the electrical parameters of the desulfurization system in real time, gives a quantization score, assists operators to monitor, thereby achieving the purposes of reducing the operation intensity of the operators on duty monitor, reducing the workload of the operators on duty monitor, improving the efficiency of the monitor, improving the predictive diagnosis level of the electrical parameters and realizing less operators on duty.

(electrical parameter-upper threshold allowed or lower threshold allowed) +80=95-95+80=80.
Wherein the safety is 80, and the optimization score is 95-95=0 (i.e., the optimization score reference value).
For another example, if the electrical parameter is a battery pack circuit battery voltage, the value is 90, 110, or the range of the preset limit value is 90-100, the allowable upper limit threshold of the battery pack circuit battery voltage is 105, the allowable lower limit threshold is 95, the limit upper limit threshold is 110, the limit lower limit threshold is 90, the optimal value is 100, and the emergency level 2. The safety score reference value is 0 and the optimization score reference value is 0. At this time, the electric parameter of the battery voltage of the battery pack loop is scored as a safety score reference value+an optimization score reference value=0+0=0.
Wherein, the safety is 0, and the optimization score is 0.
It should be noted that the safety scoring reference value and the optimization scoring reference value are obtained based on a scoring mapping relationship, and the scoring mapping relationship includes the safety scoring reference value and the optimization scoring reference value corresponding to different emergency levels of the electrical parameters. For example, when the emergency level is 2, the security score reference value and the optimization score reference value are 0 and 0, respectively.
In another embodiment, when the emergency level is 1, the safety score reference value and the optimization score reference value are 60 and 0, respectively.
Assuming that the electrical parameter is the battery voltage of the battery loop, when the emergency level is 1, the value is 90, 110 or the allowable upper limit threshold of the battery loop battery voltage exceeds the preset limit value range of 90-100 is 105, the allowable lower limit threshold is 95, the limit upper limit threshold is 110, the limit lower limit threshold is 90, and the optimal value is 100. At this time, the electric parameter of the battery voltage of the battery pack loop is scored as a safety score reference value+an optimization score reference value=60+0=60. At this time, the safety was 60, and the optimization score was 0.
The electric parameters and equipment of the desulfurization system are displayed with corresponding icons. The electrical parameter score can be displayed green within 80-100, yellow within 60-79 and red below 60 minutes. Therefore, the embodiment of the invention evaluates the electrical parameters of the desulfurization system in real time, gives a quantization score, assists operators to monitor, thereby achieving the purposes of reducing the operation intensity of the operators on duty monitor, reducing the workload of the operators on duty monitor, improving the efficiency of the monitor, improving the predictive diagnosis level of the electrical parameters and realizing less operators on duty.
Referring to fig. 2, in other aspects of the embodiments of the present invention, step 200, after determining the electrical parameter score of each electrical parameter based on each electrical parameter, the preset allowable value range, the preset limit value range and the optimal value corresponding to each electrical parameter, further includes:
step 300, determining an electrical module score based on the electrical parameter scores of each electrical parameter belonging to the same electrical module.
The electronic device may also determine an electrical module score based on the electrical parameter scores for each electrical parameter belonging to the same electrical module.
In other aspects of embodiments of the invention, step 300 of determining an electrical module score based on the electrical parameter scores for each electrical parameter belonging to the same electrical module comprises: and determining the electric module score based on the electric parameter score of each electric parameter and the weight level of each electric parameter under the condition that the electric parameter score of each electric parameter belonging to the same electric module is respectively larger than the set threshold value.
Specifically, all electrical parameters in the electrical module are above a set threshold (e.g., 80 minutes), and the electrical module score may be obtained by weighted averaging according to the weight levels of the plurality of electrical parameters.
In the embodiment of the invention, the weight level of the current value parameter is set to be 1; the voltage value parameter weight level is set to 2, and the UPS system and the DC system parameter weight level is set to 2.
For example, taking a utility electrical module as an example, the utility electrical module includes three electrical parameters, namely, battery pack loop battery voltage, UPS system bypass feeder cabinet output voltage, and dc feeder screen dc bus voltage. The weight level and electrical parameter score for each electrical parameter are shown in table 1:
TABLE 1
Then, the electrical module score of the utility electrical module is: (94×2+97×2+93×2)/(2+2) = 94.67.
It should be noted that, the electrical module scores can be displayed through a DCS picture, and the electrical parameters with the same attribute are put together, so that the operator can conveniently find the electrical parameters. The electric module scores can be green in 80-100, yellow in 60-79 and red below 60 minutes. Therefore, the embodiment of the invention determines the electric module score based on the electric parameter score of each electric parameter belonging to the same electric module, evaluates the electric module in real time, gives the quantitative score, and assists the operator in monitoring the panel, thereby achieving the purposes of reducing the panel operation intensity of the operator on duty, reducing the panel operation workload, improving the panel efficiency, improving the predictive diagnosis level of the electric parameters and realizing less person on duty.
In other aspects of embodiments of the invention, step 300 of determining an electrical module score based on the electrical parameter scores for each electrical parameter belonging to the same electrical module comprises: in the event that there is an electrical parameter score for one of the electrical parameters that is less than the set threshold, an electrical module score is determined based on the electrical parameter score for the electrical parameter that is less than the set threshold.
That is, when there is an electrical parameter score of one electrical parameter of the same electrical module that is smaller than the set threshold value (80 minutes), the electronic device takes the electrical parameter as the electrical module score. For example, when one electrical parameter of one electrical module is 75 points, the other electrical parameters of the same electrical module are all higher than 80 points, the 75 points are scored as electrical modules.
It should be noted that the electrical module score may be green in 80-100, yellow in 60-79, and red below 60 minutes. Therefore, the embodiment of the invention determines the electric module score based on the electric parameter score of each electric parameter belonging to the same electric module, evaluates the electric module in real time, gives the quantitative score, and assists the operator in monitoring the panel, thereby achieving the purposes of reducing the panel operation intensity of the operator on duty, reducing the panel operation workload, improving the panel efficiency, improving the predictive diagnosis level of the electric parameters and realizing less person on duty.
In other aspects of embodiments of the invention, step 300 of determining an electrical module score based on the electrical parameter scores for each electrical parameter belonging to the same electrical module comprises: if the electrical parameter scores of the plurality of electrical parameters are each smaller than the set threshold value, an electrical module score is determined based on the smallest value among the electrical parameter scores of the plurality of electrical parameters that are smaller than the set threshold value.
That is, when the electrical parameter score of the plurality of electrical parameters of the same electrical module is smaller than the set threshold (80 points), the electronic device determines the electrical module score by taking the smallest value among the electrical parameter scores of the plurality of electrical parameters. For example, when the plurality of electrical parameters of one electrical module are 75 minutes, 76 minutes and 77 minutes, respectively, the other electrical parameters of the same electrical module are all higher than 80 minutes, the minimum 75 minutes of the plurality of electrical parameters is scored as the electrical module.
In addition, when equipment of the desulfurization system is out of operation, no electrical module scoring is involved. The electrical module score of the electrical module is 0 when any one of all electrical parameters in the electrical module triggers an emergency item.
It should be noted that the electrical module score may be green in 80-100, yellow in 60-79, and red below 60 minutes. Therefore, the embodiment of the invention determines the electric module score based on the electric parameter score of each electric parameter belonging to the same electric module, evaluates the electric module in real time, gives the quantitative score, and assists the operator in monitoring the panel, thereby achieving the purposes of reducing the panel operation intensity of the operator on duty, reducing the panel operation workload, improving the panel efficiency, improving the predictive diagnosis level of the electric parameters and realizing less person on duty.
Referring to fig. 3, in other aspects of the embodiments of the present invention, step 200, after determining the electrical parameter score of each electrical parameter based on each electrical parameter, the preset allowable value range, the preset limit value range and the optimal value corresponding to each electrical parameter, further includes:
step 400, determining an electrical subsystem score based on the electrical parameter scores for each electrical parameter belonging to the same electrical subsystem.
The electronic device may also determine an electrical subsystem score based on the electrical parameter scores for each electrical parameter belonging to the same electrical subsystem.
In other aspects of embodiments of the invention, step 400, determining an electrical subsystem score based on the electrical parameter scores for each electrical parameter belonging to the same electrical subsystem, comprises: in the case where the electrical parameter score of each electrical parameter belonging to the same electrical subsystem is respectively greater than the set threshold, an electrical subsystem score is determined based on the electrical parameter score of each electrical parameter and the weight level of each electrical parameter.
Specifically, all electrical parameters within the electrical subsystem are above a set threshold (e.g., 80 minutes), and the electrical subsystem score may be averaged by weighting according to the weight level of the plurality of electrical parameters.
For example, the electrical parameter scores and weight levels for the electrical parameters of one electrical subsystem are shown in table 2:
TABLE 2
Then, the electrical subsystem scores for the electrical subsystem: (91×2+93×1 … … 91 ×1)/(2+1 … … +1) =95.6.
It should be noted that, the electrical subsystem scores can be displayed through a DCS picture, and the electrical parameters with the same attribute are put together, so that operators can conveniently find the electrical parameters. The electrical subsystem scores may be green in 80-100, yellow in 60-79, and red below 60 minutes. Therefore, the embodiment of the invention determines the score of the electrical subsystem based on the electrical parameter score of each electrical parameter belonging to the same electrical subsystem, evaluates the electrical subsystem in real time, gives out the quantitative score and assists the operator to monitor the panel, thereby achieving the purposes of reducing the panel operation intensity of the operator on duty, reducing the panel operation workload, improving the panel efficiency, improving the predictive diagnosis level of the electrical parameters and realizing less person on duty.
In other aspects of embodiments of the invention, step 400, determining an electrical subsystem score based on the electrical parameter scores for each electrical parameter belonging to the same electrical subsystem, comprises: in the event that there is an electrical parameter score for one of the electrical parameters that is less than the set threshold, an electrical subsystem score is determined based on the electrical parameter score for the electrical parameter that is less than the set threshold.
That is, when there is an electrical parameter score of one electrical parameter of the same electrical subsystem that is smaller than the set threshold (80 minutes), the electronic device takes the electrical parameter as the electrical subsystem score. For example, when one electrical parameter of one electrical subsystem is 75 points, the other electrical parameters of the same electrical subsystem are all above 80 points, the 75 points are scored as electrical subsystems.
It should be noted that, the electrical subsystem scores can be displayed through a DCS picture, and the electrical parameters with the same attribute are put together, so that operators can conveniently find the electrical parameters. The electrical subsystem scores may be green in 80-100, yellow in 60-79, and red below 60 minutes. Therefore, the embodiment of the invention determines the score of the electrical subsystem based on the electrical parameter score of each electrical parameter belonging to the same electrical subsystem, evaluates the electrical subsystem in real time, gives out the quantitative score and assists the operator to monitor the panel, thereby achieving the purposes of reducing the panel operation intensity of the operator on duty, reducing the panel operation workload, improving the panel efficiency, improving the predictive diagnosis level of the electrical parameters and realizing less person on duty.
In other aspects of embodiments of the invention, step 400, determining an electrical subsystem score based on the electrical parameter scores for each electrical parameter belonging to the same electrical subsystem, comprises: in the event that there are a plurality of electrical parameters having electrical parameter scores that are each less than the set threshold, an electrical subsystem score is determined based on a minimum of the electrical parameter scores of the plurality of electrical parameters that are less than the set threshold.
That is, when there are a plurality of electrical parameters of the same electrical subsystem whose electrical parameter score is smaller than the set threshold (80 points), the electronic device determines the electrical subsystem score by taking the smallest value among the electrical parameter scores of the plurality of electrical parameters. For example, when the plurality of electrical parameters of one electrical subsystem are 75 points, 76 points and 77 points, respectively, the other electrical parameters of the same electrical subsystem are all higher than 80 points, the minimum 75 points of the plurality of electrical parameters are scored as the electrical subsystem.
In addition, when the equipment of the desulfurization system is normally shut down, the equipment is counted by 100 minutes. Any one of the electrical parameters within the electrical subsystem scores a score of 0 when that electrical subsystem triggers emergency item 3. When any one of all the electrical parameters in the electrical subsystem triggers the emergency item 5, the electrical parameter score is recorded as 0 score, and the electrical subsystem score is counted according to the weighted average of the electrical parameters.
It should be noted that the electrical subsystem score may be green in 80-100, yellow in 60-79, and red below 60 minutes. Therefore, the embodiment of the invention determines the score of the electrical subsystem based on the electrical parameter score of each electrical parameter belonging to the same electrical subsystem, evaluates the electrical subsystem in real time, gives out the quantitative score and assists the operator to monitor the panel, thereby achieving the purposes of reducing the panel operation intensity of the operator on duty, reducing the panel operation workload, improving the panel efficiency, improving the predictive diagnosis level of the electrical parameters and realizing less person on duty.
In summary, the invention automatically evaluates the electrical parameters of the desulfurization system in real time, displays the electrical parameter scores in the DCS system, and the operation panel personnel can conduct targeted monitoring and operation according to the electrical parameter scores, the electrical module scores or the electrical subsystem scores, thereby solving the problems that the DCS images are required to be continuously browsed and adjusted through operation experience in the past, reducing the workload of the operation panel and improving the panel efficiency.
