Abstract
This paper proposes a coordinated controller for a permanent-magnet synchronous generator wind turbine to enhance its low voltage ride through capability. In the proposed method, both rotor side and grid side converters are cooperatively controlled to regulate the DC link voltage during the grid fault. Moreover, at the fault clearance, the grid side converter produces the previous power value which is the maximum power in normal operation. It prevents excessive power production at the fault clearance in order to reduce the rotor load. From the proposed method, better transient response of the DC link voltage could be obtained with less rotor acceleration. We validated the proposed method using MATLAB/Simulink SimPowerSystems and compared the performances of with and without the coordinated control.
