Impact of Wind Energy Conversion System on Fault Clearance Time

The Critical Clearance Time analysis of an electric power system is crucial in designing the protective devices. The Critical Clearing Time analysis of Wind Energy Conversion System on IEEE 14 bus is done in this work using Power System Analysis Toolbox. Using Time Domain Simulation, the rotor angle stability of the power system is investigated under stable and unstable conditions for determining Critical Clearing Time. A three-phase fault is simulated at various buses to analyze the effect of fault location and critical clearing time on the system stability. The perturbations of the rotor angle are also analyzed during fault and verified whether it satisfies the Fault Ride Through standards.
