Abstract

Abstract: As a kind of economical and clean renewable energy, wind power generation is more and more widely used. Wind power plants are far away from the load center and the output power is highly random. Therefore, the control of reactive power, voltage and network loss at public connection points are more difficult. The automatic voltage control system uses the real-time operating data of the power grid to select the best reactive voltage control scheme from the perspective of the entire system. It takes the voltage safety and quality as the conditional limit, takes the economy of the system as the goal, and optimizes the voltage in real-time control. This article gives a control strategy for the problem of inability to smooth transition and repeated oscillations in the signal processing of the abnormal state of the AVC system. The upper and lower limit planes of voltage and reactive power are divided into 27 areas, and each area corresponds to different control strategies. This method can be used to achieve smooth transition of control strategy, real-time voltage optimization control.
