摘要
为提升新能源电能质量多扰动信号检测的精确度,并降低检测结果与扰动实际开始和结束时间之间的误差,开展新能源电能质量多扰动信号自动检测方法研究。先引入数学形态学理论,对新能源电能质量信号进行消噪和滤波处理,后以此为基础,结合网格分形理论,实现对多扰动信号的时间定位与自动检测。实例结果表明,新的检测方法展现出了极高的检测精度,能准确地定位信号扰动的发生时间,应用效果较好。
To improve the detection accuracy and reduce the error between the detection results and the actual start and end times of disturbances with respect to electric quality multi-disturbance signals of new energy generations,this work made a preliminary attempt to establish an automatic detection method.First the mathematical morphology theory was introduced to denoise and filter electric quality signals.Based on this,combined with grid fractal theory,time location and automatic detection of multi-disturbance signals were achieved.The proposed method was indicated,by a case test,highly accurate in locating the occurrence time of signal disturbance,and thereby potentially promising.
