为了实现对矿山备用电厂同步电机运行状态的检测,给出了一种能够判断同步电机运行状态的方法.根据电机不同运行状态下产生声音信号的不同,利用 MATLAB强大的编程功能对同步电机音频信号进行滤波,并利用小波分析确定信号的参数特征,最后通过比对所得参数确定同步电机所处的运行状态.实验表明,MATLAB分析得到的常态和次暂态运行的同步电机声音参数差异较大,所提出的方法能够较好地判断同步电机所处的运行状态,便于实现对同步电机更好的控制,具有潜在实用价值.
Deep Mining of Characteristic Variables of Abnormal Sound of Faulty Generators Using Wavelet Window
In order to detect operational status of synchronous motors in mines'auxiliary power plants,a method to deter-mine operational status of synchronous motors was proposed and studied.According to the different sound signals genera-ted by the motor under different status,the MATLAB powerful programming function was used to filter the sound sig-nals.Then the parameter characteristics of sound signals were obtained using wavelet analysis,and finally the motor oper-ation status was determined by comparing the obtained parameters.It was concluded from the experiment that the use of MATLAB analysis could obtain synchronous motor sound parameters with large difference between normal status and sub-normal status.The proposed method thereby can facilitate accurate determination of motor operational status and real-ization of better control of synchronous motors,exhibiting potential practical applicability.
