This paper proposes a terminal crowbar protection technique for Doubly Fed Induction Generators (DFIG) to protect the rotor converter and enhance network stability during grid disturbances. Simulation test using MATLAB-Simulink toolbox is implemented on a 9 MW wind farm exports its power to 120 KV grid. The simulation is performed using different values of crowbar resistances. The variations of...

Recently, there has been a fast development and deployment of wind energy to meet the increasing electrical power demand and to limit the use of fossil fuels. More and more wind farms are planned far from shore because of good wind condition and less visual impact. This is so called offshore wind farm (OWF). In such a situation, high voltage direct current (HVDC) transmission is a favorable opt...

This paper presents a comparative assessment of four low voltage fault ride through (LVFRT) techniques that alleviate the effects power imbalance during AC network faults for source converter (VSC)-based wind energy conversion systems (WECSs). The appraised include software-based coordinated control (CC) technique, commercially available dumping resistor (DR) and two storage techniques, namely,...
