Description

In the static set of power distribution network REACTIVE POWER/VOLTAGE with the DYNAMIC DISTRIBUTION coordinated control system
Technical field
The present invention relates to a kind of power distribution network relevant control technology, especially relate in a kind of static set of power distribution network REACTIVE POWER/VOLTAGE and the DYNAMIC DISTRIBUTION coordinated control system.
Background technology
In the power distribution network running, the reasonable control of REACTIVE POWER/VOLTAGE and adjustment are vital for reducing grid loss, improving the quality of power supply.For power distribution network, the means of reactive power/voltage control and adjustment are relative less, take capacitor group, load tap changer as main, owing to be subjected to the restriction of cost of investment, and dynamic reactive compensation device, less such as configurations such as SVC.
Coordinate the content that control comprises two aspects with DYNAMIC DISTRIBUTION in the power distribution network REACTIVE POWER/VOLTAGE static set: the on the spot distribution control of the concentrated optimal control of static passive compensation device (capacitor group) and dynamic reactive compensation device (such as SVC etc., comprise load tap changer).For the power distribution network that does not have dynamic reactive compensation device (such as SVC) etc., the control that distributes is on the spot mainly carried out for load tap changer.In addition, when concentrated optimal control went wrong, distribution control mode can be used as the reserve of concentrating optimal control, also static passive compensation device is controlled on the spot; Vice versa.That is to say that it is mutually for subsequent use concentrating with the control that distributes.
Find that through the retrieval to the prior art document mode of existing power distribution network REACTIVE POWER/VOLTAGE CONTROL and adjustment is divided into two kinds.A kind of is the mode of controlling on the spot, with regard to VQC control, generally is to form control strategy according to nine territory figure, tap and the local capacitor group of transformer is controlled, in order to keep the in-situ balancing of reactive power.Because there is certain defective in nine territory figure control strategies, nine territory figure had been proposed successively again afterwards to improve, or even the control mode of 17 territory figure, such as document " synchronizing calculation method of transforming plant voltage reactive control range " (Automation of Electric Systems, 2003,27 (8): 70-74.), " transforming plant voltage reactive control strategy and implementation " (Automation of Electric Systems, 2001,25 (15): 47-50.), " the new discussion of VQC control principle--by " nine districts figure " to " five districts figure " " (Automation of Electric Systems, 2004,28 (19): 92-95.), " research of electric substation's voltage and Reactive Power Automatic Regulating Criteria " (China Power, 1995,28 (7): 12-15).In general, the capacity of capacitor group can not be by large-scale smooth adjustment, so cause under a lot of operational modes, reactive power is impossible in-situ balancing, therefore also just has horizontal and vertical support issue idle between the different substation.From this angle, the limitation of control displays on the spot, because be not that angle from the overall situation considers a problem, the effect of optimization is relatively relatively poor.In addition, because there is certain limitation in the action frequency of electric equipment, the capacitor group often can not be by switching frequently, and for the larger situation of localised load fluctuation, certainly will cause VQC (voltage power-less control) control system to start frequently and operate, this also is one of major defect of Partial controll.Another kind is central controlled mode, be AVC (automatism voltage control) control, in scheduling or main website side unification capacitor group and load tap changer are controlled, such as document " research and the realization of Jiangsu Power Grid AVC main station system " (Automation of Electric Systems, 2004,29 (22): 83～87.), " Anhui Power Grid automatism voltage control (AVC) system and realization " (Automation of Electric Systems, 2004,28 (8): 20～22.), but because Distribution Network Equipment parameter, measurement data, and the error of the computational efficiency aspect of optimized algorithm existence itself, formed decision scheme often is difficult to carry out.
