基于自抗扰的STATCOM抑制风电次同步振荡
Damping of Sub-synchronous Oscillation for Wind Turbine Generator Using STATCOM Based on Active Disturbance Rejection Control
摘要
Abstract
The wind turbine may exist sub-synchronous oscillation problems when large-scale wind power is transmitted by a fixed series of lines. The static synchronous compensator(STATCOM)is a full-controlled FACTS device with fast response,it is good at damping as a sub-synchronous oscillation suppressor. However,because STATCOM is a nonlinear system,the traditional PID control is difficult to achieve satisfactory results.To solve this problem and improve the robustness of the system,considering that ADRC has good adaptability and low error, according to complex torque coefficient method,a STATCOM control strategy was designed to suppress the sub-synchronous oscillation of wind farm based on the fact that the STATCOM reactive power compensation capability was maintained.The system of double-fed induction generator transmitted by fixed series lines with STATCOM connected was established on PSCAD/EMTDC,which verify the validity of the control strategy.关键词
