Online Fault Diagnosis Simulation of Stator Winding of Marine Synchronous Generator Based on Wavelet Analysis

  • MATLAB/Simulink was applied to simulate the shorted fault between two circles of stator winding of marine synchronous generator.Then the wavelet function in minor MATLAB wavelet toolbox was adopted to analyze the sig nal of malfunction and recognize the fault characteristics.Simulation results show that it is practical for the use of wavelet to conduct online monitoring and diagnosis to the fault of stator winding of marine synchro nous generator,hence,providing theoretical basis for the design of apparatus for online faults monitoring and diagnosis of stator winding of marine synchronous generator.
