With the rapid development of wind power generation, permanent magnet synchronous wind power generation system has become the mainstream model of wind power system. The reliability of a converter system in a wind power system has important impacts on the power conversion process in the entire wind power system. Open-circuit failure of converter’s IGBT as the key failure mode of converter system should be realized real-time detection and localization. This paper studies the open-circuit fault of converter in permanent-magnet direct-drive wind power generation system. The wind power generation system is simulated by Matlab/Simulink simulation. A real-time fault detection algorithm isproposed based on generator operating characteristics and modified Park transformation. The method is suitable for thefault diagnosis of wind power generation with variable wind speed and multiple-noise interference without any additional hardware facilities.
