In this paper investigations on a fixed speed wind farm with squirrel cage induction generators (SCIG) directly connected to the grid in combination with a STATCOM based Indirect Torque Control (ITC) under unbalanced grid voltage fault are given by means of theory and simulations and also different kinds of control methods are discussed. Under unbalanced grid voltage dips causes additional generator torque oscillations. The simulation results clarify the effect of voltage compensation by a STATCOM on the operation of a SCIG wind farm which inference the improvement of voltage stability and reduction of torque oscillation.
