Reactive power return batch control system

Abstract

The invention discloses a reactive power return batch control system which comprises a prefecture and county regulation and control main station, a transformer substation and a data scheduling server,and is characterized in that the prefecture and county regulation and control main station comprises a reactive power return control unit, a scheduling control unit and a monitoring execution unit; the reactive power return control unit is used for matching from a preset plan library according to the current reactive power parameters to obtain a corresponding preset plan A, wherein the preset plan A comprises a control strategy for the plurality of station controlled devices; the scheduling control unit is used for adjusting the control strategy in the preset plan A according to the actual condition of the capacitor or the no-load line to obtain an actual plan B; and the monitoring execution unit is used for generating a control signal matched with the actual plan B and sending the control signal to the transformer substation through the data scheduling server so as to be executed by the transformer substation. The invention aims to provide the reactive power return batch control system, and when the system is reactive, the capacitors or no-load lines of a plant station are selected to be cut off, so that the function of quickly controlling the reactive power of the system is achieved.

Description

technical field [0001] The invention relates to a system used in the technical field of electric power, in particular to a reactive power feedback batch control system. Background technique [0002] During the light load period of the power grid, a large amount of reactive power feedback will be generated. If a large amount of reactive power is fed back, it may cause insulation damage to the high-voltage system and cause system grid accidents. The traditional way of adjusting reactive power is that the supervisor cuts off the capacitors of different plants and stations according to the situation of reactive power return in the power grid area. This method will consume a lot of energy for the supervisors to find the capacitors that have been put into use in different plants and stations, and measure and remove the reactive power capacity. Simultaneous removal of capacitors requires double verification by the operator and the monitor, and rapid removal of reactive power canno...
