In this paper, we present the design of a fuzzy logic supervisor for the control of active and reactive power which is generated by fixed speed wind energy conversion systems (WECS). First, the modelling of a three-phase induction generator driven by a horizontal axis wind turbine is described. An adjustable capacitor bank is plugged at the connection point with a Static Var Compensator (SVC), which is controlled to regulate the rms voltage. The obtained model is reduced by taking into consideration the dynamics of the system. A fuzzy logic-based supervisor is proposed in order to minimize variations of the generated active power and the stator voltage. The regulation of the rms voltage is performed while imposing a reactive power reference. The pitch angle of the turbine blades is set to obtain the maximum wind power. The obtained performances of the proposed supervisor are then presented.
