Validated short circuit modeling of Type 3 Wind Turbine Generator with crowbar protection

Abstract

With fast increasing penetration of wind generation around the world, it is important to document accurate short circuit models of different types of wind turbine generators (WTGs) and wind farms. This paper documents and analyzes the short circuit response of Type 3 WTG with crowbar protection. The model is first simulated and validated using field data from a wind farm having Type 3 WTGs. PSCAD is used for simulation. The validated model is used to study the short circuit behavior of the WTG. Based on the study, Thevenin model of the wind farm is derived.
