Description
Summary:The integration of large scale wind farms bring serious influence to the stability of power system. In this paper, a simulation model of doubly-fed induction generator (DFIG) based wind turbine with capacity of 1.5 MW is constructed using the module of parameter identification in simulation software DIgSILENT. Then, to decrease the modeling error came from the difference between the wind energy utilization factor table in the DIgSILENT model and that of the actual wind generator, a new modified wind energy utilization factor table is developed. Finally, the DFIG-based wind turbine model, with corresponding identified parameters, is used to the practical wind generator by its actual operation data. The simulation result show that the active power output by the constructed simulation model has the similar tendency with the practical wind power data, i.e. the proposed method and the constructed model are effective.
