Transient analysis of DFIG wind turbines in multi-machine networks

This paper presents the transient analysis of doubly fed induction generator (DFIG) wind turbines in multiple machine networks. Computer simulations were carried out using IPSA software. The performance of DFIG wind turbines and controllers was presented using three different network configurations including a large wind farm connected to a multimachine system. Simulation results illustrated the consequences of modeling the main system by an infinite bus model or by an equivalent loaded synchronous generator. It was observed that in this case the control system design and tuning plays a fundamental role in the dynamic characteristics of the wind farm and its interaction with the power network
