A Consideration on the Voltage Stability of Wind Generators

Recently the wind power generation has attracted special interest and many wind power stations are being in service in the world. In the wind power stations, induction machines are mostly used as a generator. Since induction machines can become unstable during a fault in power system, like a step-out of synchronous machines, it is important to analyze the stability of power system including wind generators. This paper presents a consideration on the stability of induction generators from a point of view of voltage stability
