Abstract
This paper presents an investigation on transient stability of power systems for a wind driven generator. The model considers the swing equations of two generators including a wind turbine generator in a power system while a fault happens at one of the transmission lines. Most stability studies model a wind turbine driven generator by a machine with small inertia that leads to instability of the machine during any fault. In this paper we considered that the machine is connected to a heavy flywheel to increase the stability during fault condition. The result of numerical simulation of the generators are presented and discussed.
