Abstract

Wind energy from renewable energy sources, the share of electric power system is increasing faster than other sources. This requires the analysis of the effect of the wind power plants have on the power system in connection with the network. The wind produces energy-dashed and variable power, which can cause some disruptive effects. In this study, a short circuit analysis was performed using the DIgSILENT PowerFactory program. Minimum short circuit analysis calculations have been performed for 15 wind turbines and 19 bus-bar wind power plants. The error current has been reduced to a minimum by changing the transformer connection and ground resistance for the most commonly encountered phase-to-ground short circuit analysis. This application has been developed against more complex and costly methods. This prevents the generators from switching to island mode after a phase-to-ground short circuit current is affected by the fault.
