STATCOM and Capacitor Banks in a Fixed-speed Wind Farm

Abstract

Wind Farms are the viable solution for delivering clean energy in near future. There are many difficulties in ensuring higher quality power into the grid, as demanded by the more and more stringent grid codes. The solution of these problems could be solved by Flexible Alternate Current Transmission Systems (FACTS) devices in the system and particularly the Statatic synchronous condenser (STATCOM). Which uses the principle reactive power (injection or absorption).One of the main causes of disconnection of wind network is the variation of voltage (drop voltage or over voltage) at the bus bar connection. The use of STATCOM, allows regulating the voltage and maintaining the grid connected wind even under certain severe conditions of disturbance.In this paper, we propose a study of the importance use of STATCOM when it installed in a wind farm and we will try to see the effect of injecting reactive power in order to maintain the voltage at the nominal value. This opportunity offers the possibility of connecting the wind farm to the grid. The choice of this study is justified by simulation in MATLAB.
