Summary

The impact of electrical transients of asynchronous wind generators on the synchronous generators is often ignored to keep the analysis of multimachine systems simple. A steady drift of slip from the nominal value, while of no consequence from power flow viewpoint, will exhibit erroneous transient profile. This article presents a multimachine power system model using a unified rotor angle concept for the asynchronous machine. A frequency controller has been installed on the induction generator to eliminate the steady state slip error. Simulation results show that the induction generator angle dependent transform used along with the frequency controller yield good dynamic behavior of the multimachine system eliminating the slip dependent transients.
