A new permanent magnet synchronous wind-power generation grid-connected system
摘要
Abstract
This paper puts forward a new permanent magnet synchronous wind-power generation grid-connected system based on solid state transformer. The high frequency transformer is added into the power electronics converters to realize an electrical isolation between the rectifier and the inverter. The output voltage of the inverter can be 10 kV and the grid-connected current is reduced. The super capacitor storage device is added to the DC bus, so that the wind generation system has strong ability of low voltage ride through. The model of the above mentioned system is constructed and its key control segments are analyzed and designed. The simulation results show that in this system, the grid-connected impact current is small and the capability of LVRT is strong. Therefore, it is a kind of valid method for the wind generation system to connect to the grid.关键词
