改进PR控制在直驱风机变流器中的应用
The Application of Improved PR Controller in Converter System of DD-PMSG
Generally, the converter system of direct-drive permanent magnet wind turbine uses vector control strategy which based on PI controller. The traditional PI controller needs complex coordinate transformation, and adds the cross-coupling terms and compensation terms of feed-forward,all this will affect the robustness and the dynamic response performance of the system. To solve such problems, this paper presents an improved PR controller, and applies it to the direct-drive permanent magnet wind turbine converter system. Through analyzing the principles, and establishes the simulation model in PSCAD, verified the improved PR controller"s advantages, proved the effectiveness of the application of improved PR controller in the converter system of direct-drive permanent magnet wind turbine.
