Specific implementation mode
Micro-capacitance sensor off-load method, apparatus, system and storage medium provided in an embodiment of the present invention, are mainly used in micro-capacitance sensor In power supply system, by the real time monitoring to load, power supply, switch and energy-storage travelling wave tube etc., obtains micro-capacitance sensor and urgent feelings occur Condition and when frequency being caused to drop to the frequency values of setting active power vacancy, pass through the excision by load according to priority orders Or the power back-off using energy-storage travelling wave tube is restored micro-capacitance sensor frequency value and is arrived to reach the balance of active power shortage in micro-capacitance sensor Rated value maintains micro-capacitance sensor frequency in a rational fluctuation range, to realize the stable operation of micro-capacitance sensor.Research hair It is existing：
(1), low-frequency load shedding function is integrated in line protective devices, when the line protective devices detect micro- electricity When the frequency for the circuit protected described in net is less than setting valve, and after meeting certain delay requirement, the line protective devices Control cuts off the circuit of the protection to achieve the purpose that cut off load.But since the line protective devices are distributed collection At it is each the action between each line protective devices need to can be made to be independent from each other in circuit to be protected, be can not phase Mutually coordinate；And the control logic of the line protective devices is very simple, only considers the Control of decreasing load of a wheel, can not be accurate Ground cuts off load.Therefore low-frequency load shedding function is integrated in line protective devices it is not high to cut off the accuracy of load, And harmony is excessively poor, it is difficult to effectively solve the stability problem of micro-capacitance sensor frequency.
(2), centralized low frequency load shedding equipment is configured.Whole feeder lines are divided into base by the method by load importance Epicycle and special wheel, when micro-capacitance sensor frequency declines, according to drop to different frequency setting values come by take turns substantially with it is special Wheel cuts off load respectively.But due to this method investment when on-site cable be laid with workload it is very big, cause the method at This is very high, and due to the centrality of centralized low frequency load shedding equipment function, can make the reliability requirement of described device It is very high, if described device itself goes wrong, then can make a big impact to Control of decreasing load.Therefore, configuration centralization is low Frequency load-shedding equipment is of high cost and device itself such as goes wrong will cause prodigious influence come the method for cutting off load, therefore The method also is difficult to effectively solve the stability problem of micro-capacitance sensor frequency.
In addition, belonging to opened loop control for the implementation process of above two micro-capacitance sensor off-load method, distribution is had ignored The influence of load real time information in mains side does not account for the different brackets of the concrete condition and failure when operation, past It is cut toward that can cross, causes unnecessary economic loss；And low frequency load shedding equipment must wait for that frequency is reduced to setting valve in the above method It is following just to act, the best mute time may be missed.
A kind of micro-capacitance sensor off-load method, apparatus of offer of the embodiment of the present invention, system and storage medium, high-precision can cut Except load, excision load can be begun to when frequency begins to decline the frequency values of setting, avoid frequency further under Drop, can fast and accurately cut off load, to reach the balance of the active power of micro-capacitance sensor, to make the extensive of micro-capacitance sensor frequency Rated value is arrived again, ensures the stable operation of micro-capacitance sensor.The realization, the function and the advantages of the object of the present invention will in conjunction with the embodiments, It is described further with reference to attached drawing.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to It is of the invention in limiting.
As shown in Figure 1, one embodiment of the invention proposes a kind of micro-capacitance sensor off-load method, it is applied to piconet controller, it should Method includes the following steps.
Step 101, the mains frequency of the micro-capacitance sensor is monitored.
Specifically, piconet controller monitors the mains frequency of the micro-capacitance sensor in real time.
Here, the piconet controller can be distributed in the master control room of substation in equal room areas.Usually, power grid Frequency stabilization maintains 50HZ or so, i.e. the rated value of power grid is generally 50HZ.When micro-capacitance sensor off-grid operation, such as occur non- When planned off-network or power failure tripping, micro-capacitance sensor frequency may drastically decline, and utilize piconet controller It monitors the mains frequency of the micro-capacitance sensor in real time, can make the frequency situation of change of piconet controller real-time awareness micro-capacitance sensor, Be conducive to micro-capacitance sensor frequency once occur fluctuating range it is unreasonable when, corresponding measure can be acquired immediately with reach maintain frequency it is steady The purpose being scheduled near rated value.
Step 103, the operation of power networks parameter that intelligent monitoring terminal is sent is received.
Specifically, the operation of power networks parameter that piconet controller real-time reception intelligent monitoring terminal is sent.
Further, the operation of power networks parameter for receiving intelligent monitoring terminal and sending, including：Receive intelligent monitoring terminal The power supply active power and distributed generation resource of transmission can issue additional power；Wherein, the power supply active power includes：Micro-capacitance sensor is by simultaneously When net switchs to off-network, the active power absorbed from bulk power grid when grid-connected, alternatively, one or more power supply trippings in micro-capacitance sensor When, the active power that is provided by one or more of power supplys before tripping；It is micro- electricity that the distributed generation resource, which can issue additional power, Net own power source can put into the active power in micro-capacitance sensor, including：In micro-capacitance sensor energy-storage travelling wave tube store energy and provide Active power.
Further, it is described receive intelligent monitoring terminal send power supply operating parameter, further include：Receive intelligent terminal hair The active power of the load sent and the reference numeral of load；Wherein, the determination of the reference numeral of the load, including：According to not Ad eundem is grouped load, to the first priority orders of group load setting, to the second priority of load setting in group load Sequentially；The load is numbered according to the first priority orders and the second priority orders.
Specifically, in one embodiment, the load in micro-capacitance sensor is divided into m groups according to load level, indicates to participate in subtracting with s Load group load group priority orders (i.e. the first priority orders), s for since 1 a series of natural numbers (s=1, 2 ... ..., m), this group of load priority of the smaller expressions of s is lower；Load number has n in every group, indicates that the group for participating in off-load is negative with q A priority orders (i.e. the second priority orders) of load in lotus, q be since 1 a series of natural numbers (q=1, 2 ... ..., n), the load priority is lower in q this group of load of smaller expression；By the load in micro-capacitance sensor according to the first priority Sequence and the second priority orders are numbered.Wherein, the load in micro-capacitance sensor is excellent according to the first priority orders and second First grade sequence is numbered, can be as shown in table 1 below：
Table 1 is based on the reference numeral of the load of " section thinking "
As shown in table 1, wherein (P11, P12, P13... ... P1q) indicate that one group of lowest priority in the first priority is born Lotus, (Ps1, Ps2, Ps3... ... Psq) indicate the first priority in highest priority one group of load；Wherein, (P11, P21... ... Ps1) indicate that the load of lowest priority in the second priority in load, (P are organized in place1q, P2q... ... Psq) indicate that load is organized at place In in the second priority highest priority load；Wherein, P11Indicate lowest priority and the second priority in the first priority The load of middle lowest priority, PsqIndicate the negative of highest priority in highest priority in the first priority and the second priority Lotus.
It should be noted that here, the load of the micro-capacitance sensor is grouped according to load level, can according to load confession Electric reliability and power supply are divided into different group loads, for heavier in political, economically caused loss or influence degree etc. The first priority that the group load wanted defines is higher.For example, in one embodiment, can load in micro-capacitance sensor be divided into level-one group and born Lotus, secondary groups load, three-level group load three groups of loads；Wherein, completely non-critical load is level-one group load, not too important Load be secondary groups load, very important load is three-level group load.In this way, according to the hierarchal grouping of load importance, The importance degree of each load in micro-capacitance sensor can be distinguished, can make when the decline of micro-capacitance sensor occurrence frequency, active power occur When vacancy, completely non-critical load can be first cut off, then cuts off the little load etc. of importance, it is more rational to realize The sequence of cutting load reduces the damage of its people brought because cut off load economically, political, in life etc. to the greatest extent Evil.
It should be noted that piconet controller receives pair of the active power and load for the load that intelligent monitoring terminal is sent It should number, the active power of each load can be recorded in real time according to the carrying out practically situation of distributed electrical source load, also, By making reference numeral to each load, piconet controller can be enable quickly and accurately to count the total active power of group load And in described group of load single load active power value, follow-up intelligent monitoring terminal can be enable to be instructed according to cutting load accurate True finds mutually the group load in requisition for excision or single load.
Step 105, when the mains frequency drops to the frequency values of setting, had according to the operation of power networks parameter acquiring Work(power shortage.
Specifically, when piconet controller monitoring mains frequency drops to the frequency values of setting, piconet controller is according to connecing The operation of power networks parameter that intelligent monitoring terminal is sent is received, active power shortage is obtained.
Further, when piconet controller monitoring mains frequency drop to the frequency values of setting when, piconet controller according to The power supply active power and distribution for receiving intelligent monitoring terminal transmission can issue additional power, according to the power supply active power and divide Cloth can issue additional power and obtain active power shortage.
Specifically, in one embodiment, for grid type micro-capacitance sensor, frequency is mainly supported by bulk power grid, if bulk power grid It breaks down and makes micro-capacitance sensor off-grid operation, such as when unplanned property off-network, have little time to control dominant eigenvalues, if before off-network Micro-capacitance sensor absorbs active power from bulk power grid, and it will cause micro-capacitance sensor active power shortages, if there are many active power shortage, and Load shedding may be such that frequency degradation even collapses not in time.Here, it is opened when piconet controller monitors micro-capacitance sensor frequency When beginning drops to the frequency values of setting, piconet controller is according to the power supply active power and distribution for receiving intelligent monitoring terminal transmission Formula can issue additional power and obtain active power shortage；Wherein, the power supply active power is the micro-capacitance sensor that intelligent monitoring terminal obtains The active-power P absorbed on interconnection before off-networkL, the distributed generation resource can issue additional power and be considered for intelligent monitoring terminal The active-power P that the distributed generation resource that can be put into after off-network can be issued additionalDG；Here, the active power shortage can be power supply Active-power PLPower P can be issued additional with distributionDGDifference, i.e. PLQ=PL- PDG。
In another embodiment, for the micro-capacitance sensor of off-network type, when occurring the case where power failure tripping in micro-capacitance sensor, Frequency may also can rapid decrease.Here, when piconet controller monitors the frequency values that micro-capacitance sensor frequency begins to decline setting When, piconet controller according to receive intelligent monitoring terminal send power supply active power and distribution can issue additional power obtain it is active Power shortage；Wherein, the power supply active power be intelligent monitoring terminal obtain micro-capacitance sensor before power supply tripping power supply send out Active-power PG, it is that can be put into after intelligent monitoring terminal considers power supply tripping that the distributed generation resource, which can issue additional power, The active-power P that distributed generation resource can be issued additionalDG；Here, the active power shortage can be power supply active-power PGWith distribution Formula power supply can issue additional power PDGDifference, i.e. PLQ=PG- PDG。

Wherein, PsIndicate total active power of s group loads, PsqIndicate the active power of q-th of load in s groups, PLQIt indicates to need The active power shortage of excision, PthresholdIndicate the threshold value of setting, wherein the threshold value PthresholdIt may be configured as：Respectively The active power for organizing peak load in the set of the active power of minimum load in load, for example, priority in the first priority Active power for minimum load in 1 group load is P1min, minimum load in priority is 2 in the first priority group load Active power be P2min..., the active power of minimum load is P in the group load that priority is s in the first prioritysmin, Then the threshold value can be set as Pthreshold=max (P1min, P2min... ..., Psmin).This method includes the following steps：
Step 21~the step 24 is corresponded with step 11 described in Fig. 3 corresponding embodiments~step 14；
Step S25 sends excision P to intelligent monitoring terminalsqInstruction does not send excision instruction；
Specifically, piconet controller determines the active-power P for needing to cut off by judgingLQIt is less than the first priority The total active-power P for the group load that middle priority orders are ssWhen, then piconet controller judges the wattful power for needing to cut off Rate PLQWhether it is greater than or equal in the group load that priority orders are s in the first priority that priority orders are in the second priority The active-power P of the load of qsq, first priority orders are cut off as in s groups if it is, being sent to intelligent monitoring terminal Second priority orders are the cutting load instruction of the load of q, if it is not, then cutting load instruction need not be sent.
Step S26 redefines the active power shortage P for needing to cut offLQ；
Specifically, piconet controller redefines the active power shortage PL for needing to cut offQ。
Step S27, | PLQ|≤Pthreshold；
Specifically, piconet controller judge described in also need to excision remaining active power shortage whether be less than or equal to set Fixed threshold value Pthreshold, if so, S29 is thened follow the steps, if not, thening follow the steps S28.
Step S28, q=q+1；
Specifically, micro-capacitance sensor control determines that the remaining active power shortage for also needing to excision is greater than described set by judging Fixed threshold value PthresholdWhen, then sequentially it is the preferential of the second priority q in s groups by q=q+1, i.e., in described first priority Grade sequence plus 1.
Step 29, it sends energy-storage travelling wave tube to intelligent monitoring terminal and compensates PLQControl instruction.
Specifically, when piconet controller is by judging that it is described that the determining remaining active power shortage for also needing to excision is less than The threshold value P of settingthresholdWhen, piconet controller sends energy-storage travelling wave tube to intelligent monitoring terminal and compensates remaining active power Vacancy PLQControl instruction so that intelligent monitoring terminal control energy-storage travelling wave tube compensates the remaining active power shortage PLQ。
It should be noted that the method can be to need direct excision group load according to the judgement of active power shortage, Or single load is cut off in a manner of approaching the threshold value of the setting by singulation load, so that intelligent monitoring terminal can be pressed The mode that group load and single load are combined carries out load excision, and energy-storage travelling wave tube can also be utilized to balance remaining wattful power Rate vacancy, enables micro-capacitance sensor frequency to be quickly restored to rated value.
Fig. 5 is the flow instance figure of micro-capacitance sensor off-load method in one embodiment of the invention, wherein with micro-capacitance sensor according to power grid After operating parameter obtains active power shortage, how according in the way of cutting group load and single load is combined needs are determined The load of excision and how determining illustrates for the transmission of control instruction.Wherein, micro-capacitance sensor internal loading is according to load etc. Grade is divided into m groups, and priority orders in the first priority are indicated with s, s be since 1 a series of natural numbers (s=1,2 ... ..., M), this group of load priority of the smaller expressions of s is lower；Load number has n in every group, indicates that priority is suitable in the second priority with q Sequence, q are a series of natural numbers (q=1,2 ... ..., n) since 1, and load priority is lower in q this group of load of smaller expression. Wherein, PsIndicate total active power of s group loads, PsqIndicate the active power of q-th of load in s groups, PLQIt indicates to need The active power shortage of excision, PthresholdIndicate the threshold value of setting.This method includes the following steps：
Step 31~the step 37 is corresponded with step 11 described in Fig. 3 corresponding embodiments~step 17；
Step S38：|PLQ-Psq|≤Pthreshold；
Specifically, when piconet controller determines the active power shortage P for needing to cut off by judgingLQIt is less than first The active-power P for the load that priority orders are q in the second priority in the group load that priority orders are s in prioritysqWhen, Then piconet controller judges the active power shortage PL for needing to cut offQIt is s with priority orders in first priority Group load in priority orders are q in the second priority load active-power PsqDifference absolute value whether be less than or Equal to threshold value Pthreshold, that is, judge | PLQ-Psq| whether it is less than or equal to Pthreshold；If so, thening follow the steps S39, such as Fruit is no, thens follow the steps S310.
Here, it should be noted that when | PLQ-Psq|≤PthresholdWhen, the active power shortage P for needing to cut offLQ With the single load P organized in load for needing to be removedsqThe two difference is smaller, therefore just considers to sacrifice the Psq, cut off the Psq Corresponding load；When | PLQ-Psq| ＞ PthresholdWhen, the active power shortage P for needing to cut offLQWith the group for needing to be removed Single load P in loadsqThe two difference is bigger, even if cutting off the P at this timesqCorresponding load, remaining wattful power Rate is also greater than threshold value, therefore the P of active power shortage is directly carried out using energy-storage travelling wave tubeLQBalance.
Step S39：Excision P is sent to intelligent monitoring terminalsqInstruction, redefines PLQ；
Specifically, when piconet controller determines the active power shortage P for needing to cut off by judgingLQWith described first The active-power P for the load that priority orders are q in the second priority in the group load that priority orders are s in prioritysq's The absolute value of difference is less than or equal to threshold value PthresholdWhen, the piconet controller is to described in intelligent monitoring terminal transmission First priority orders are the cutting load instruction for the load that the second priority orders are q in s groups, and redefine and also need to cut off Active-power PLQ。
Step S310：Energy-storage travelling wave tube, which is sent, to intelligent monitoring terminal compensates PLQControl instruction.
Specifically, when piconet controller determines the active power shortage P for needing to cut off by judgingLQWith described first The active-power P for the load that priority orders are q in the second priority in the group load that priority orders are s in prioritysq's The absolute value of difference is greater than threshold value PthresholdWhen, piconet controller sends energy-storage travelling wave tube to intelligent monitoring terminal and compensates institute State remaining active power shortage PLQControl instruction so that intelligent monitoring terminal control energy-storage travelling wave tube compensation it is described remaining Active power shortage PLQ。
It should be noted that the method can be to need direct excision group load also according to the judgement of active power shortage Be by single load, so that intelligent monitoring terminal can carry out load excision in such a way that group load and single load are combined, and And energy-storage travelling wave tube can also be utilized to balance remaining active power shortage, so that micro-capacitance sensor frequency is quickly restored to rated value.
