Low Voltage Ride-Through of DFIG Wind Turbine Systems Using Crowbar

Thanh Hai Nguyen, Kyung-Hyun Kim, Dong‐Choon Lee

Open publisher page 2 citations

Abstract

This paper deals with the operation of doubly-fed induction generator(DFIG) for wind turbine systems under the grid fault conditions using crowbar. The crowbar protection is able to prevent the high fault rotor currents which flow into the rotor-side converter and a fast DC voltage increasing. Only one crowbar resistor through diode rectifier connected to the rotor side of DFIG is considered. The paper provides a design for selecting the crowbar resistance, and describes the control strategy for crowbar when the grid fault occurs and is cleared. Simulation results are shown for a 2MW DFIG system using PSCAD.
