摘要
分析了探测线圈检测电机转子绕组匝间短路故障的机理,应用小波变换算法对所得信号进行特征提取。采用MATLAB与VC++混合编程,将MATLAB的M文件直接嵌入VC环境,完全脱离MATLAB运行。以VC++图形界面作为前台,实现信号采集、系统框架的搭建和界面的绘制;利用COM Builder技术实现MATLAB与VC++之间的通信;以MATLAB为后台,进行数据分析和计算,实现电机转子绕组匝间短路故障判断。结果表明系统有良好的实际应用效果。
We analyzed the mechanism of detecting the inter-turn short-circuit in rotor winding fault with detecting coil,and extracts the signal feature with wavelet transform algorithm.Hybrid programming of MATLAB and VC＋＋ is used,embedding ding M document of MATLAB into the VC and making them run normally without MATLAB.The signal collecting,system frame constructing and interface drawing can be carried out by adopting VC＋＋ graphical interface as the front-stage,while using COM builder technology to implement communication between MATLAB and VC＋＋.With MATLAB as the back-stage,the inter-turn short-circuit in rotor windings fault can be judged through the data analysis and calculation.The results show that the system has a good effect in practical application.
