摘　　要：应用MATLAB/Simulink仿真软件,对船舶同步发电机定子绕组两种匝间短路故障进行了建模仿真,然后运用MATLAB小波工具箱里的小波函数对仿真的故障信号进行了分析,实现了故障特征提取,表明小波方法对船舶同步发电机定子绕组故障实现在线监测并诊断是可行的,为设计船舶同步发电机定子绕组故障在线监测诊断仪提供了理论依据。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 signal 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 synchronous generator,hence,providing theoretical basis for the design of apparatus for online faults monitoring and diagnosis of stator winding of marine synchronous generator.
