These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
In the related technology, the gas turbine and the combined cycle unit thereof are rapidly developed due to the advantages of high efficiency, low emission, flexible start and stop, good peak regulation performance and the like, the gas turbine is mainly used as the peak regulation unit in the current power grid structure, the start and the stop are very frequent day by day and night, the hot start is most frequent, the hot start accounts for more than 90% of the total start mode, and how to reduce the hot start gas consumption of the gas turbine becomes an important research subject at present. For the F-level heavy-duty gas turbine, after the unit is started and connected to the grid in a thermal state mode, an operator directly inputs a preselected load mode according to an operation order and raises the load to be about 25MW, and after the load of the gas turbine is stabilized, the load is increased or decreased according to the exhaust temperature of the gas turbine. And because the inherent characteristics of the combustion engine, the output of the combustion engine is directly influenced by the atmospheric environment temperature, the combustion engine load needs to be manually and repeatedly adjusted when the combustion engine load corresponding to the temperature of the exhaust gas is increased to 566 ℃ under different environment temperatures is different, the exhaust temperature is kept to be not more than 566 ℃, and the warming-up is carried out when the exhaust temperature is stabilized in a higher temperature range, during the manual adjustment of the combustion engine load, if the exhaust temperature is more than 566 ℃, the combustion engine RB (RUNBACK, auxiliary machine fault load reduction) function is triggered, the unit automatically exits the preselected load mode and rapidly reduces the load, at this time, an operator needs to reenter the preselected load mode and place the preselected load mode into a proper target set value, and readjust the combustion engine load to keep the exhaust temperature not more than 566 ℃. On the other hand, in the high-pressure air inlet waiting stage of the steam engine warming, the higher the engine load is, the higher the engine exhaust temperature is, the higher the high-pressure main steam temperature can meet the air inlet condition at the fastest speed, and the shorter the waiting time for air inlet is. Therefore, how to realize the load full-process automatic control of the unit in the warm-up stage and improve the load of the combustion engine within the system requirement range as much as possible so as to improve the exhaust temperature of the combustion engine and enable the high-pressure main steam temperature to meet the steam admission condition at the fastest speed is important for shortening the starting time of the unit and reducing the gas consumption of the unit during starting.
In response to the shortcomings and drawbacks of the prior art, and as illustrated in FIG. 1, the exemplary embodiment provides a method of controlling a load of a gas turbine, comprising:
s11, collecting the current ambient temperature of the atmospheric environment of the gas turbine;
and S12, configuring initial load control parameters according to the environment temperature so as to control the gas turbine to operate according to the initial load control parameters.
According to the gas turbine load control method provided by the exemplary embodiment, the atmospheric environment temperature of the gas turbine when the gas turbine is started is collected, the optimal initial load control parameter of the gas turbine is configured according to the environment temperature, the load of the gas turbine is increased, so that the exhaust temperature of a unit is quickly increased to be nearby 566 ℃, the exhaust temperature is kept stable all the time, the unit is warmed up at 565-566 ℃, and the start time of the unit is shortened; thereby reducing the gas consumption of the unit during starting.
In step S11, the current ambient temperature of the atmosphere in which the gas turbine is located is collected.
In this exemplary embodiment, the method described above may be performed by a background control system of the gas turbine. A temperature measuring device for collecting ambient temperature can be provided for the gas turbine unit, and the temperature measuring device is connected with the control system and transmits data. For example, before the unit is started, the control system controls the temperature measuring device to collect the ambient temperature, and the temperature measuring device feeds back the collected ambient temperature data to the control system.
In step S12, an initial load control parameter is configured according to the ambient temperature to control the operation of the gas turbine according to the initial load control parameter.
In this exemplary embodiment, after obtaining the current ambient temperature, the control system may execute a preselected load control mode on the gas turbine, execute an initial load configuration logic in the preselected load control mode, configure initial load control parameters of the plant according to preset rules, and execute the initial load control parameters in the preselected load control mode. Wherein the initial load control parameters may include: an initial load parameter, an initial load rate parameter.
Specifically, the calculation formula of the initial load parameter may include:
where F1 (x) is the initial load value and ATID is the ambient temperature.
Because the output of the combustion engine is directly influenced by the atmospheric environment temperature, the load values of the combustion engine corresponding to the condition that the exhaust temperature of the combustion engine is increased to be nearby 566 ℃ under different environment temperatures are different, and the optimal initial load set value is obtained according to the load parameters when the exhaust temperature of the combustion engine of the unit is increased to be nearby 566 ℃ after the unit is started under different environment temperatures. Let the initial load parameter WM _ SP2= F1 (x).
Preferably, in some exemplary embodiments, F1 (x) = [ -5 ℃,55MW;5 ℃,50MW; 46MW at 10 ℃;15 ℃,40.5MW;20 ℃,34.5MW;25 ℃,31; 28.5MW at 30 ℃;35 ℃ C., 25MW ].
Further, in some exemplary embodiments, the configuration of the initial load parameters may also be configured in consideration of one or more of a unit model of the gas turbine, a planned load rate, and a planned unit exhaust warm-up period.
At the same time, an initial load rate parameter in the preselected load control mode may also be defined. For example, the initial load rate may be set to 14, 10, etc.
Referring to fig. 2, the method may further include:
step S21, when the exhaust temperature of the gas turbine is higher than a preset exhaust temperature threshold value and a fault load reduction RB function is triggered, collecting the actual load when the RB function is reset;
and S22, correcting the initial load control parameter according to the actual load to obtain a corrected load control parameter, and controlling the combustion engine load of the gas turbine by using the corrected load control parameter.
Specifically, a temperature measuring device for the exhaust temperature of the gas turbine and a measuring device for the power of the gas turbine unit can be configured for the gas turbine unit, so that the exhaust temperature and the load of the gas turbine unit can be acquired in real time when the gas turbine unit runs.
And (3) as the combustion engine runs with an initial load, the exhaust temperature of the combustion engine slowly rises, when the initial load is higher, the exhaust temperature of the combustion engine exceeds 566 ℃, the combustion engine RB is triggered, the combustion engine exits the preselected load control mode, the load set value correction logic is executed, and the load is quickly reduced. When the exhaust temperature of the combustion engine is lower than 566 ℃ along with the reduction of the load of the combustion engine, the combustion engine RB can be automatically reset, and at the moment, an appropriate load set value needs to be reset, and a load pre-selection function is started.
Executing load set value correction logic after the combustion engine RB is triggered by the overtemperature of the exhaust temperature of the combustion engine; the actual load of the engine when the engine exhaust temperature drops to 566 deg.C and engine RB is reset is recorded as MW _ RB and an appropriate load modifier is added based on this load as the new engine load set point. Specifically, the calculation formula of the load correction may include:
MW_SP1[i]＝MW_RB[i]+K2
wherein i represents the ith combustion engine exhaust temperature overtemperature trigger combustion engine RB; MW _ RB [ i ] represents the actual load of the combustion engine when the exhaust temperature of the combustion engine is reduced to 566 ℃ and the combustion engine RB is reset after the combustion engine RB is triggered by the overtemperature of the exhaust temperature of the combustion engine for the ith time; MW _ SP1[ i ] represents the corrected load set value of the combustion engine after the ith combustion engine exhaust temperature is overtemperature to trigger the combustion engine RB; k2=1WM.
In the exemplary embodiment, in order to ensure that the load of the combustion engine is switched undisturbed by the load set value in the process of exiting and putting the combustion engine into the preselected load control mode, load real-time tracking logic can be configured. When the gas turbine is in a preselected load mode, MW _ SP0 tracks the load set value feedback, otherwise, tracks the current actual load of the gas turbine.
I.e., L83PS = tune, MW _ SP0= L90PSEL;
MW _ SP0= DWATT when L83PS = FALSE
Wherein L83PS represents a preselected load control mode; l90PSEL represents the load set value feedback.
In this example embodiment, referring to fig. 3, the method may further include:
step S31, collecting current real-time load parameters of the gas turbine;
and step S32, when the real-time power difference value between the current real-time load parameter and the initial load parameter is larger than a preset power threshold value, correcting the initial load rate parameter according to the real-time power difference value.
Specifically, in order to avoid an excessive deviation of the load set value from the actual value during the load increase, a load rate limiting function may be provided. Specifically, when the deviation value delta WM between the load set value and the actual value is less than 5MW, the default initial load rate is selected as the load rate. Wherein the formula may include:
Rate_SP＝Rate_SP0＝K1＝14
△WM＝L90PSEL-DWATT
wherein, rate _ SP represents the unit load Rate; DWATT represents the actual load of the unit; l90PSEL represents the unit load set point feedback.
For example, when the deviation Δ WM between the load set value and the actual value exceeds 5MW, the load rate limiting function is triggered, and the load rate selects the output value of the rate limiting function. The formula may include:
Rate_SP＝Rate_SP1＝F2(x)
f2 (x) = Med [14, 14-0.7 × Δ WM,0] (where Med [ ] is a function taking an intermediate value)
Preferably, in some exemplary embodiments, F2 (x) = [5, 14;10,8.5;15,4;20,0]. For example, when the deviation Δ WM of the load set value from the actual value is 5, the load rate is set to 14.
In this exemplary embodiment, when the real-time power difference between the current real-time load parameter and the initial load parameter is greater than a preset power threshold, the method further includes: a rate limiting control mode is executed for the gas turbine.
In this example embodiment, referring to fig. 3, the method may further include:
s31, collecting the current real-time load parameters of the gas turbine and the corresponding current exhaust temperature;
and S32, when the current real-time load parameter meets a parameter monitoring interval corresponding to the initial load control parameter and the current exhaust temperature is lower than a preset exhaust temperature threshold value, correcting the initial load control parameter to increase the load of the gas turbine.
Specifically, after the unit is started in a hot state and the load is brought to an initial load parameter, the exhaust temperature of the gas turbine is stably maintained to be 565-566 ℃ through fine adjustment of the load until the high-pressure steam inlet condition is met. The load correction logic only takes effect before the high-pressure air inlet condition is met after the unit is connected to the grid, namely WM1= WM1_ SP; otherwise WM1= K6=0.
The load correction WM1_ SP is obtained by subjecting WM1_ SP0 to rate limitation and amplitude limitation. Wherein, the load reduction lower limit L = K5= -3; when the load of the unit is increased to be close to a target value (namely F1 (x) -DWATT is more than 1), triggering a high limit function, wherein the load increasing high limit H = K3=5; otherwise, H = K4=0. After the gas turbine is ensured to be brought to the vicinity of the initial load and the exhaust temperature of the gas turbine is still lower than a set value, the load correction high limit value is triggered to carry out automatic loading.
WM1_SP0＝F3(X)*△T
△T＝TTXM_SP-TTXM
TTXM_SP＝565.5
Wherein: WM1_ SP0 represents a unit load correction value after load amplitude limitation and rate limitation; WM1_ SP represents a unit load correction value which is not subjected to load amplitude limitation and rate limitation; TTXM _ SP represents an engine exhaust temperature set value; TTXM represents an actual exhaust gas temperature of the combustion engine; f3 (X) represents a section of an inertia function
Wherein when the actual temperature TTXM is higher than the set exhaust temperature TTXM _ SP, i.e., Δ T < 0, T =5, k =0.3; otherwise, T =5,k =0.25. Namely, the function of ensuring that the load reduction amount is larger and the load is reduced rapidly when the actual exhaust temperature of the combustion engine is higher than the exhaust temperature set value, and the load increase amount is smaller and the load is increased slowly when the actual exhaust temperature of the combustion engine is lower than the exhaust temperature set value.
In this exemplary embodiment, referring to fig. 4, the method may further include:
s41, collecting the current exhaust temperature corresponding to the gas turbine;
and S42, when the current exhaust temperature is lower than a preset exhaust temperature threshold and meets a parameter monitoring interval corresponding to the exhaust temperature threshold, correcting the initial load rate parameter.
Specifically, the load Rate WM1Rate _ SP is obtained by amplitude limiting the Rate limiting function F4 (x). For example, the upper limit value H =14 and the lower limit value L =0 may be configured.
That is, WM1Rate _ SP = Med [14, F4 (x), 0]; wherein: med [ ] is a function taking the median value.
F4(x)＝5+0.75*|△T|
That is, the closer the actual exhaust temperature of the internal combustion engine is to the exhaust temperature set value, the smaller the load rate, and conversely, the larger the load rate.
Through F3 (X) and F4 (X) functions, the functions of slowly increasing the load when the exhaust temperature of the combustion engine is lower than a set value and quickly reducing the load after the exhaust temperature is over-temperature are achieved.
According to the load control method of the gas turbine, the unit automatically controls the load in the whole process before high-pressure steam inlet, the load of the gas turbine is increased within the system requirement range as far as possible, the exhaust temperature of the gas turbine is rapidly increased to 566 ℃, the temperature of high-pressure main steam meets the steam inlet condition at the fastest speed, the starting time of the unit is shortened, the starting gas consumption of the unit during hot starting is reduced, and the running economy of the unit is further improved.
Further, referring to FIG. 5, the exemplary embodiment also provides a gas turbine load control system 50, comprising: an ambient temperature acquisition module 501 and a combustion engine load configuration module 5. Wherein,
the ambient temperature acquisition module 501 may be configured to acquire a current ambient temperature of an atmospheric environment in which the gas turbine is located.
The engine load configuration module 502 may be configured to configure an initial load control parameter based on the ambient temperature to control the operation of the gas turbine based on the initial load control parameter.
