Abstract

This paper establishes a simulation model for a doubly fed induction generator (DFIG) connected with a power grid by using the vector control scheme. The model consists of a wind turbine, a doubly fed generator, power converters and a vector control strategy. The simulation model is built by using PSCAD/EMTDC. We also investigate the operating characteristics of a grid with the DFIG by considering respective wind speed fluctuation and short-circuit fault in the grid. Experiment results verify the correctness of the simulation model and the relative stability in the operating process of the simulated grid. This work provides a useful simulation platform for further studying the transient stability of the DFIG connected with power grid and more effective control strategies
