Impacts Of Wind Turbines On The Optimal Coordination Of Overcurrent Relays

Summary/Abstract: In coordination procedure generators outages consideration as well as lines outages are important. Asynchronous generators, which are intensively used in wind turbines, cannot usually sustain their fault currents contribution during the coordination period. It is possible that they are disconnected from the network before the fault is cleared. Therefore, wind turbines with asynchronous generator consideration are more important than others. These features produce additional constraints in optimal coordination schemes. This paper investigates the effects of wind turbines in optimal coordination of Overcurrent (OC) relays and defines the additional terms in optimal constraints due to the disconnection of wind turbines. The proposed method was applied in a power system, the results of the applied method are shown and the wind turbines effects are clarified in the paper.
