摘要

This article analyzes the influence of constant speed wind turbine generators on power system oscillation. First, mode distributions have been compared between the constant speed wind turbine generator and the synchronous generator connected to an infinite bus, and the outcome of machine vulnerability to oscillatory instability is identified. The influence of the length of transmission interface between the generator and infinite bus is also studied. Then, the influence of load increase and penetration of a constant speed wind turbine generator on power system oscillation is studied in detail. Finally, the effect of increased penetration of constant speed wind turbine generator power for different configurations, namely single turbine, wind farm, and scattered wind turbine, has been studied. In all of the unstable cases, a static var compensator is used to improve the stability of the system.
