A New Control Strategy to Improve Voltage Stability of the Power System Containing Large-scale Wind Power Plants

摘要：

In this paper,the control strategy to improve voltage stability of power system was studied after large scale wind power plants integrated.And the strategies to improve the transient voltage stability of wind power plants were introduced firstly.Based on the analysis of characteristics that voltage stability of the fix speed wind generator,a new control strategy that can improve the voltage stability of the power system containing large-scale wind power plants was proposed by employing permanent magnet synchronous generators(PMSG) together with static compensator(STATCOM).The stability of transient voltage can be improved by using full power wind turbine close to generators to provide reactive power.STATCOM control model,fixed-speed wind turbine model and the model of permanent magnet were established,the voltage stability of wind power plants can be improved using full power permanent magnet synchronous generator with together STATCOM to provide reactive power compensation to constant speed wind during disturbance.The simulation carried out on the test system verify the proposed control strategy can effectively enhance the transient voltage stability of the power plants containing large scale wind generators.
