【Abstract】 Along with both the increase of the non\|linear level and the electronically switched loads in power systems, the power quality is becoming increasingly poor. The main power quality problems in power systems are systematically summarized. The three digital analysis methods based on time domain, frequency domain and wavelet transform are expounded respectively and the application of them in electricity quality study is presented in detail.更多还原
