Research on Application of Automatic Voltage Control Technology at the Substation of the Power Grid
Automatic voltage control(AVC)ensures voltage qualification rate of power grid nodes and provides effective support for power grid stability.Combined with the control principle of substation AVC,the author analyzed the control strategy of AVC system,and designed the safety constraint function.Finally,the author proposed the debugging technical requirements for the substation AVC dynamic and joint debugging,which has guiding significance for the design of safety restraint function and the debugging technology of substation AVC in pumped storage power station.
