Application and Analysis of Reactive Power Compensation Mode for Wind Power Generation System

The asynchronous generator is mostly applied in the wind generation system.The performance of the reactive power compensator is of vital importance when the wind asynchronous generator is being put in grid.This article expounds some questions about the wind generator such as rational reactive power compensation,matching of the capacitors,selection of switching apparatus and decreasing of the inrush current when capacitors are being switched in.It is of great significance for reliable and efficient operation of the generator and is important for adequately utilization of wind power resource and increasing of the economic efficiency.
