The Influence of Rotor Arrester on Low Voltage Ride through Behavior of Doubly-Fed Induction Generator

Abstract

Low voltage ride through (LVRT) behavior is one of the key indices of wind turbine grid-integration evaluation. The key electric components of wind turbine, such as converter, control system had been researched. While other components of wind turbine, such as the rotor arrester, are also non-ignorable. Firstly, overvoltage of rotor during the LVRT is analyzed and one failure test has been presented because of rotor arrester performance. Finally, the rotor arrester has impact not only on the LVRT ability of wind turbine, but also damage to other hardware by on-site testing.
