Wind Farm Grid Voltage Stability Researching Based on Cascade STATCOM

Though most wind turbine use induction generator, when wind induction generator with power generation, it will produce a series of power quality problems such as voltage fluctuations. This paper discusses the mathematical model of the wind induction generator and cascade STATCOM, raised through the parallel cascade STATCOM to solve the wind farm grid voltage stability problems. Simulation results show that this method can effectively and quickly solve the problem of wind farm grid voltage stability, has a very important significance of the reliable operation of wind turbines, improving grid efficiency, making full use of wind energy resources, improving economic efficiency.
