WIND FARM TRANSIENT BEHAVIOR OPTIMIZING BY CAPACITOR BANKS SWITCHING

The main problem of self exciting induction generators are used in wind farms is its requirement a reactive power to generate output voltage. In order to provide the mentioned reactive power, using of fixed capacitors, that they are connected to generator terminals, is one of the usual methods. Since the requirement of induction generators to reactive power is varied by load changes and wind speed therefore using of variable and switch able capacitor banks can be one of the methods to generate reactive power for induction generators and to keep voltage stability. In this paper accrued transient condition by capacitor banks switching in wind farm are simulated by MATLAB and methods are suggested to optimize mentioned conditions.
