摘要
Abstract
The control strategies for generator -side converter and grid -side converter for the permanent magnet direct-driven wind power generation system are analyzed. The active power of grid-side converter is introduced to generator in order to limit the electromagnetic power of the generator and decrease the DC-link over-voltage. The grid-side converter exports reactive power rapidly to increase the grid-side voltage. Simulations are carried out using MATLAB/Simulink 7.10 and the simulation results verify the effectiveness and feasibility of the proposed control strategies.关键词
