Wind Turbine Generator System

In order to maintain the stable operation of grid system, the grid company requires wind turbine generator system with low-voltage ride through (LVRT) capability. With this issue, the article builds a double-fed wind turbine generator system model, Crowbar circuit strategy model to protect rotor-side inverter and fault pitch control strategy model to inhibition rotor speed during grid fault. Then all the models and strategies are verified by the simulation of grid low voltage. The simulation results show that these models can complete LVRT.
