Fault ride through study of doubly fed induction generator wind turbine in real-time simulation environment

In this paper, the fault ride through (FRT) of the doubly fed induction generator (DFIG) wind turbine is studied. The study is done by using a simulation environment in which the network is simulated using Real-Time Digital Simulator (RTDS) and the wind turbine is simulated using dSPACE in real time. The effect of transient flux on the operation of the wind turbine during a network voltage dip is analyzed. The simulation results show that the network voltage support can be maximized if the transient flux is compensated. In addition, it is proposed that different crowbar resistances should be used during the voltage drop and the voltage recovery in order to avoid network short-term voltage stability problems.
