In this work, it is analyzed the dynamic behaviour of two methodologies to improve large-disturbance stability performance of fixed-speed wind turbines based on induction generators directly connected to distribution networks. The first is the reactive power compensation, where two technologies are investigated: SVC (Static Var Compensator) and DSTATCOM (Distribution Static Synchronous Compensator). The second one is the blade pitch angle control. The dynamic performance of these generators during short-circuits in the network due to different control signal of the electronic and mechanical devices are investigated. The electronic devices have showed better performances when controlled by terminal voltage signals, while the mechanical devices with rotor velocity or the combined signal.Downloads
