摘要
Abstract
The fault in the power unit of generator excited system seriously affects the stable operation of the generator. Therefore, it was very important to find out and remove the fault accurately as soon as possible. The faults in the power unit were undergone simulation analysis with MATLAB/Simulink software. According to the result of the simulation analysis, a fault diagnosis method of the three-phase input current waveform and the changing of peek-to-peek value was proposed. On the foundation of the analysis, a fault diagnosis system of generator excitation power unit based on the software platform Labwindows/CVI of virtual instrument was developed. It was proved by experiment that the fault diagnosis system could precisely judge which thirstier goes wrong and get accurate diagnosis result.
