Abstract

This paper presents a practical method for estimation of fault ride-through capability of wind power farms composed by squirrel-cage rotor induction generators. The proposed method is based on the steady-state equivalent circuit of the induction generator and on the concepts of stable and unstable electrical-mechanical equilibrium points, which are calculated in the electrical and mechanical torque versus rotor speed space. The method has been validated by comparing the results obtained by the analytical method with those determined by dynamic simulation results.
