英文摘要	The low voltage ride through capability of wind turbines is an important indicator to measure the ability of wind power systems to be connected to the grid. With traditional control strategy, the low voltage ride-through capability with direct drive permanent magnet synchronous wind power generation system has limited. This paper improves the LVRT capability of DPMG by adding a chopper protection circuit with energy storage device to the DC side of wind power system. In this paper, the control method of Chopper protection circuit with energy storage device, the selection of energy storage components and the control principle of bidirectional converter are analyzed. The improved circuit is simulated by MATLAB/simulink. The result proves that when the grid voltage drops, the existence of the chopper protection circuit with energy storage components can maintain the input and output power balance of the system in a short time, stabilize the DC side voltage, and improve the low voltage ride through capability of the wind turbine.
