Five. embodiment
Generating set power of the present invention is coordinated the control hardware system, comprise speed regulator, microcomputer excitation regulator, programmable logic controller (PLC), electric quantity collector, comprise the operator workstation in computer and relevant being arranged on thereof, the computer installation of described operator workstation has generating set power to coordinate control computer software flow process.
Embodiment:
The concrete equipment in hydroelectric station comprises: the hydraulic turbine---HLA253-WJ-84; Hydraulic generator---SFW3200-8/1730; Speed regulator---Chongqing speed reaches water power BWT-1800 stepping microcomputer governor; Excitation unit---southwest, the Chongqing hydroelectricity control equipment KGLF of factory microcomputer excitation regulator; Programmable logic controller (PLC)---Siemens S7-2000PLC; Promise PMAC720 intelligent electric power instrument is sent in electric quantity collector---Zhuhai; Operator workstation---grind magnificent industrial computer (CPU P4 2.8G, internal memory 512M, hard disk 120G, Win2000Server, the North Sea, Guangxi milky way science and technology YH-5000 monitoring power station system).
The generating set power control method for coordinating of embodiment: at first monitor the electric quantity collector data that front end processor is gathered, analyze the power instantaneous value, provide the control result, pass through the front end processor transmitting order to lower levels again to programmable logic controller (PLC), then control speed regulator and field regulator outlet action, the control method of its realization is, having proposed synchronous coefficient in the process that generating set active power and reactive power are controlled simultaneously is this notion of reaction power factor scope, by gaining merit in real time and relation in real time idle and synchronous coefficient that the comparing electrical value harvester obtains, judge whether current state is coordinated, if exceeded boundary, respective handling is not done in then meritorious and idle adjusting, otherwise, when meritorious power does not satisfy condition, meritorious adjusting is exported to machine unit speed regulating device, and when reactive power did not satisfy condition, idle adjusting was exported to the unit field regulator.
Accompanying drawing 1 has provided the generating set power of embodiment and coordinated control computer software flow process: it is meritorious that unit control system is provided with generating set, idle and synchronous coefficient parameter, gather active power and reactive power real-time measurement values again, does reactive power satisfy condition? then return collection active power and reactive power real-time measurement values if satisfy condition, then judge meritorious if do not satisfy condition, the relation of reactive power and synchronous coefficient, exceed retaining zone? gather active power and reactive power real-time measurement values if then return, if do not exceed retaining zone, then meritorious adjusting of controller exports to speed regulator; Gather active power and reactive power real-time measurement values, does active power satisfy condition? then return collection active power and reactive power real-time measurement values if satisfy condition, judge the relation of meritorious, reactive power and synchronous coefficient if do not satisfy condition then, exceed retaining zone? gather active power and reactive power real-time measurement values if then return, if do not exceed retaining zone, then the idle adjusting of controller exports to field regulator.
The controlled step of embodiment is as follows:
At first gather electric quantity collector and upload data by the front end processor monitoring of YH-5000 monitoring power station system, next enters power cooperation control system of power generation unit, its control method enters gen-set control system according to accompanying drawing 1,1. the unit Control Parameter is set, mainly includes merit power measurement dot information P, wattless power measurement dot information Q, active power adjustable range and dead band, reactive power adjustable range and dead band, synchronous coefficient kc (reaction power factor scope).2. monitor active power and wattless power measurement value in real time, judge whether real-time active power and reactive power satisfy controlled condition, continue monitoring and judgement if in control range, then return, otherwise enter next step.3. judge the relation of active power, reactive power and synchronous coefficient, see whether be in the synchronization zone internal area, promptly check meritorious and whether reactive power is coordinated,, realize regulating outlet, otherwise do not carry out corresponding operating if the result certainly, then proceeds corresponding operation.Be embodied in: regulate for active power, in being in retaining zone, sending meritorious the adjusting and export order, otherwise do not handle, enter next round control; Then send idle adjusting outlet order for reactive power.Pass through the front end processor transmitting order to lower levels at last again to PLC control speed regulator or field regulator, thereby reach the purpose of regulating hydraulic generator unit power.
Real-time, accuracy and stability thereof in order to ensure power coordination control, the time interval that sends adjusting command to speed regulator or field regulator continuously must be greater than sending the time that order between extremely adjusting is worked, simultaneously, the power adjustments dead zone range is got minimum value in the OK range, and power stability is on weekly duty to enclose swinging back and forth and controlling the frequent movement problem of adjustment process with regard to having avoided like this.
