Analysis on Wind Power Plant Voltage Quality and Design of STATCOM Control

Due to the randomness and volatility of wind power, the problems of voltage fluctuation, harmonic and so on will have a serious impact on the power quality of power grid. (Which produces a voltage fluctuations, harmonics and other power quality problems will severely affected power grid.) The wind turbine (generator system) simulation model is established based on the Gansu Hexi grid-scale wind power projects, power quality characteristics of wind turbine grid is analyzed and the impact on the grid is proposed. STATCOM is proposed for power quality control to wind farm, and technical solutions is designed, the results of simulation analysis demonstrate the effect of STATCOM control. It provided a reference to the future management of power quality.
