Fault analysis of wind turbine generator in an isolated network

The paper deals with an HPNSWD (High Penetration No Storage Wind-Diesel) System which consists of a Wind turbine generating electrical energy when wind is available and is accompanied by a Diesel Generator which supplies energy whenever wind is unavailable. In order to implement such a system, outmost care must be taken to design auxiliary circuits and measures to improve the disturbances introduced by the addition of a wind turbine to the system. Disturbances such as change in frequency, Main Load Power, Reactive power, etc. must be checked for stability; otherwise the whole grid may fail.
