Simulation and comparison of transient stability of power system including DFIGs wind farm based on detailed model

Abstract

This article is concerned with the impact of large-scale wind farms utilizing double fed induction generator (DFIG) on the transient stability to a general power system. In the first instance, the synthetical dynamic model of the wind turbine generators (WTGs) is introduced, including pitch angle control model and the generator protective model. And then, the simulation is made to the CIGRE B4-39 standard grid through the comparison between synchronous generator integration and wind farm based DFIG integration with the same power capacity. The simulation is also contained after the load and the topological structure changed. The conclusion shows that the transient stability of the power system including DFIGs wind farm is more robust than conventional synchronous generator connected.
