摘要
The effects that wind power brought on power system protective configuration is analyzed, and the protective allocation of all electrical components when doubly-fed wind turbines connected to power grid is elaborated. Based on analysis of network connection in China, the basic mode of grid framework change during faults has been analyzed and concrete criteria for corresponding fault modes are put forward to implement fast sensing and diagnosis of faults. Taking the characteristics of protective action for wind generators into account, the action mode of protective relaying is constructed. Finally, the effectiveness of the proposed method is verified by an actual fault case in China.
