Impact of Distributed Generation on Short Circuit Level of Power System

Renewable energy is that as it is sustainable and so will never run out . Renewable energy facilities generally require less maintenance than traditional generator. Importance of conventional energy wind form is the best of energy for future. DFIG are nowadays widely used in variable speed wind power plant. The ability of the wind power plant to stay connected to the grid during disturbance is important to avoid a cascading effect due to lack of power. This paper investigate the impact of short circuit fault on the stability of DFIG wind turbine using crowbar resistance. Simulation test using MATLAB-Simulink toolbox is implemented on a 9MW, six 1.5MW turbine of wind form export its power to 120KV grid. The variation of the rotor current , rotor speed active and reactive power on wind form are investigated.
