Abstract: The electrical power generation is augmented by the deployment of renewable energy sources apart from the conventional synchronous generators (SGs). Wind energy, one of the extensively extracted renewable resource is mainly derived using induction generators (IGs). The IGs have different electrical performance characteristics depending on its type and hence their behaviour under faulty conditions are quite different as compared to synchronous generators. Researchers have proposed the peak current contribution of IGs during various faults at point of common coupling (PCC) with single machine infinite bus (SMIB). This paper presents performance evaluation of different types of IGs operating with SGs in a multi-machine power system by considering a high penetration of wind energy. The reactance diagram of multi-machine power system is deliberated. A three L-G fault is simulated at weak bus of the system and results are presented and analysed for various wind turbine generators.
