Automatic Detection Method of Electric Quality Multi-disturbance Signals of New Energy Generations
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 in-troduced 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.
