摘要
当前,整个社会对高质量电能的追求与电能质量问题日趋严峻的矛盾越来越突出,准确全面地进行电能质量分析,进而采取合理措施实现电能质量的改善和治理已十分必要。综述电能质量信号的特征提取、消噪、扰动的参数估计和扰动分类等四个电能质量分析领域的研究现状,总结了各种分析方法的优缺点和适用范围。所得结论对于进一步开展电能质量分析的研究具有参考价值。
At present, the contradiction between the pursuit of high electric power quality in the whole community and the problems of power quality becomes more and more prominent. It is necessary to carry on power quality analysis accruately and thoroughly, and take reasonable measures to improve and manage power quality. This paper summarizes the research status of four power quality analysis fields, which are feature extraction of the power quality signals, denoising, parameter estimate of power quality disturbance and disturbance classification, and sums up the advantages and disadvantages of various analysis methods and the scope of application. The conclusions have reference value for the further development of power quality analysis.
