摘　　要：以大庆油田第七采油厂低压配电网为研究背景,对该厂多处进行电能质量检测。针对存在的谐波状况,选用具有良好的伸缩、平移特性的小波多分辨率分析方法,对谐波电流进行Matlab仿真分析,通过谐波重构和误差计算,证明该方法对谐波检测具有很好的效果。Regarding low voltage distribution network of The Seventh Oil- producing Factory,Daqing Oil Field as the research background, the power quality of multi -points in this factory is detected. In view of the harmonic situation, the wavelet and multi-resolusion theory with favorable retractility and translation characteristic is selected, using Matlab to analyze the harmonic current, according to the harmonic reconstruction and the error account, the method of harmonic detection is proved to have very good performance.
