Existing AGC allocation strategy can be selected in subordinate's generator unit, allocation strategy.
In one embodiment, what each AGC can also be provided according to frequency modulation assisted hatching goes out clear as a result, sending out its subordinate
Electric unit is controlled.Specifically, go out settle accounts specified in fruit go out the clear period start when, will acceptance of the bid generator unit be set as silent
Recognize hopping pattern, the generator unit that will not get the bid is set as defaulting non-hopping pattern.Go out the acceptance of the bid generator unit of clear period for this,
During controlling it, limit deviation between its active power and real-time unscheduled power no more than go out to settle accounts fruit to
The acceptance of the bid capacity of the acceptance of the bid generator unit out.
To which each power dispatching station AGC can be carried out according to the fruit that goes out to settle accounts of unified frequency modulation assisted hatching
Frequency is adjusted, the generator unit of each power dispatching station AGC subordinate can according to its frequency modulation assisted hatching acceptance of the bid
Situation liberally undertakes frequency modulation task.
It in one embodiment, can be according to the mains frequency meter of itself real-time monitoring when AGC is in independent control mode
Region regulatory demand is calculated, and is handed down to its lower generator unit and is controlled.This time domain regulatory demand calculation method and distribution plan
Summary can continue to use existing AGC strategy.
In one embodiment, the control method of UFC includes the following steps S301 to step S307.
S301 parses clear file.
Before each clear period out starts, UFC needs to read the text clear out that frequency modulation assisted hatching is sent in advance
Part, reading at the time of, can be according to the preset periods.When the filename of clear file can be comprising going out clear with unified standard out
The character string of segment information.Out in clear file, usually give out the clear period, total acceptance of the bid capacity of each power dispatching station, with
And total acceptance of the bid capacity accounts for the whole network and always gets the bid the ratio of capacity, each power dispatching station AGC subordinate generator unit whether in
Situation and acceptance of the bid capacity are marked, the Split Factor of each power dispatching station AGC can also be provided.UFC is read from clear file out
After information above, goes out to settle accounts fruit to these and carry out plausibility check, if there is exception, alarm notification correlation operations staff.
S302, confirms whether clear file meets service condition.
After UFC completes out clear document analysis, confirmation interface can be provided, reminds total allocation and transportation administrative staff to carry out with alarm true
Recognize, settle accounts acceptance of the bid situation that the information for needing to confirm in fruit includes generator unit and the total acceptance of the bid situation of power dispatching station out,
Operations staff can judge to settle accounts whether fruit meets service condition according to the operation needs of power grid at that time, if conditions are not met, can
It is fed back to frequency modulation assisted hatching, it is desirable that go out again clear and provide and new go out to settle accounts fruit.
S303 judges whether UFC state is operating status.
The cycle of operation of UFC can be set as it is per second, when UFC monitoring frequency measure there are numberical range etc. exception when,
UFC automatically exits from operating status, adjusts to avoid mistake.When UFC state out of service, pass through the UFC issued to each AGC
Each AGC is informed in state remote signalling, and each AGC will judge in remote signalling accordingly, be transferred to independent frequency modulation control mode.When UFC is in
When operating status, into S304, this cycle of operation is otherwise exited.
S304 obtains power grid real-time frequency, and calculates real-time frequency regulatory demand according to power grid real-time frequency.It is specific to calculate
Method may refer to previous embodiment, and details are not described herein.
S305, judges whether each AGC participates in unified frequency modulation control.
For each AGC, when the unified frequency modulation state sent thereon is controllable state, and on the markers sent and UFC local day
When internal clock deviation is less than setting value, it is believed that the AGC participates in unified frequency modulation control, otherwise it is assumed that the AGC is not involved in unified frequency modulation
Control.
S306 calculates the district control deviation for participating in each AGC of unified frequency modulation control.Circular may refer to
Previous embodiment, details are not described herein.
Calculated district control deviation is handed down to corresponding AGC by S307.The mode of issuing can be, and region is controlled
Deviation is output in SCADA system as an analog quantity, then by dispatch data net, is transmitted to correspondence according to 104 specifications
Power dispatching station AGC.
In one embodiment, AGC includes the following steps S401 to step S410 in each execution period.
S401, judges whether AGC is in coordinated control mode.When AGC is arranged to coordinated control mode, enter step
S402;Otherwise S408 is entered step.
S402 judges whether UFC is operating status.If the UFC state received is operating status, S403 is entered step;
Otherwise it is transferred to and sets independent control mode for AGC automatically, be then return to step S401;
S403 judges AGC whether normal operation.If AGC is in normal operating condition, S404 is entered step;If AGC because
It is more than that the reasons such as limit value then issue announcement into abnormal operational conditions for the crucial measurement exception such as frequency, district control deviation
It is alert, it is out of service.
S404 counts the non-regulated quantity summation of each generator unit of subordinate, above send to UFC.
S405, the district control deviation issued using coordinated control mode parameter and UFC (ACE), zoning is newly-increased to adjust
Frequency demand (ARR).Circular may refer to previous embodiment, and details are not described herein.
S406 judges whether it is clear start time period out.In clear start time period out, S407 is entered step, then
Enter step S409;Otherwise S408 is entered step, S409 is then entered step.
S407 carries out the conversion of PLC mode and bandwidth control.
When current time is clear start time period, to subordinate's generator unit PLC according to the acceptance of the bid settled accounts in fruit out
Situation carries out mode conversion and control bandwidth setting.For generator unit of getting the bid, default frequency modulation mould is set by corresponding PLC
Formula is allowed to go out clear period offer frequency modulation service at this, meanwhile, it is set and adjusts bandwidth as acceptance of the bid capacity.For not middle target hair
Electric unit sets corresponding PLC to not default non-hopping pattern, be allowed to this go out the clear period frequency modulation service is not provided, only with
It is run with planned value.Adjustment band-width tactics herein are, AGC when controlling PLC, make the real-time active power of PLC with
Deviation between plan power output is no more than the adjustment bandwidth being arranged.
S408 increases frequency modulation demand newly using independent control mode parameter zoning control deviation and region.Meter herein
Calculation method can continue to use AGC Existing policies.
S409, judges whether current time enters the control period.If so, entering step S410;Otherwise terminate to execute the period.
S410 increases frequency modulation demand and unit planned value newly according to region, calculates generator unit control instruction, and as needed
