Analysis of voltage faults in the grid-connected inverter of a wind power generation system using real-time digital simulator

This paper presents the analysis of voltage faults of the grid-connected inverter of a 3MW wind power generation system (WPGS). The analysis using a real time digital simulator (RTDS) is performed and evaluated for voltage faults to enable to withstand voltage dips during transient disturbance. For validation, typical voltage sag conditions and faults are deployed to the system. Simulation and experimental results validate that the analytical model is introduced and implemented under transient grid conditions.
