Performance Analysis of Grid connected Wind Energy Conversion System with a DFIG during Fault Condition

Integration of wind turbine based on doubly fed induction generator (DFIG) into the electrical grid has become an important part of electrical generation in many countries and its importance is continuing to increase. A few of them are various speed generations, the decoupled control of active and reactive power and high power capacity. The current and future wind power situation is modeled as two cases and short circuit faults in the system are simulated. The simulations yield information on (i) how the faults impact on the wind turbines and (ii) how the response of the wind turbines influences the post-fault behavior of the power system. Here, we attempted to compare the impact, in terms of voltages, active and reactive power, of adding wind turbines into electrical power grid. Therefore, the analysis of wind power dynamics with the DFIG wind turbines has become a very important research issue, especially during transient faults.
