Open publisher page 13 citations

Abstract

In order to protect the converter of doubly fed induction generator(DFIG) and realize low voltage ride through(LVRT) during grid faults, the crowbar is usually used , since the resistor value of the crowbar effects DFIG's rotor current, reactive power output and electrical torque, it 's design is very crucial for LVRT.A novel optimal design of DFIG crowbar resistor for fault ride-through is proposed in this paper, simulations have been carried out to validate the proposed optimal design, the results demonstrate its effectiveness.
