Analysis and Simulation Study of Excitation Faults for Synchronous Motor

Excitation faults are main reason to cause asynchronous accident and influence operational quality for synchronous motor. In order to resolve the problem that fault experiments do damage to the motor and excitation equipment, the static and dynamic state character simulation model of excitation circuit and synchronous motor based on MATLAB/SIMULINK was researched. With simulation experiment for synchronous motor, the simulation waveform was offered in the excitation normal and fault condition. The results indicated that the simulation waveform is in accordance with the actual operating condition of synchronous motor and the simulation model is accurate and effective. In addition, by using the simulation model, just change very little line or some parameters, other different faults of synchronous motor can be simulated. Accordingly, some damaging tests for synchronous motor and excitation device are avoided, the test cost is economized and the test efficiency is improved greatly.
