Abstract :
In wind power station, induction machine are using as induction generator. Transient stability analysis of induction generator used in wind power station, joint to infinite bus, before and after balanced and unbalanced short circuit faults is one main issue in power system security and operation. That is necessary to know transient behavior of induction generator, when joint to network, in usual faults. In this paper we present active power, torque and speed of induction generator at balanced and unbalanced short circuit faults with dynamic equation of induction machine, with single equation of induction machine we present transient active power, torque, speed. Analysis of induction generators used in wind power system before and after three phase fault, two phase fault, single phase fault and two phase to earth fault conditions, the natural approximation to derive analytical formulas for transient conditions is proposed, and the transient behavior of induction generator is analyzed by the single equations. This paper includes three parts: modeling, simulation and analysis result.
