Wind Power Impact on Transient Fault Behaviour in Electrical Power Grid Using Doubly Fed Induction Generator

摘要

he amount of electrical energy produced by wind turbines is constantly increasing. Nowadays detailed analyses considering the impact of wind energy integration on the transmission system are required. The goal of this study is to investigate the dynamic response of a wind turbine with Doubly Fed Induction Generator (DFIG) connected to the power system during grid disturbance. The current and future wind power situations are modeled as two cases and a transient fault is simulated. In order to analyze the impact of wind energy integration in electrical power grid, a power system model has been developed, integrated with wind turbine using doubly fed induction generator and transient analyses are performed. Here, an attempt has been made to compare the impact, in terms of voltages, currents, and total harmonic distortion etc., of adding wind turbines into electrical power grid.
