Abstract
To solve the problems of anthropic factors and complex evaluation model, the idea of clustering is applied to power quality comprehensive evaluation. Power quality is estimated synthetically by the fuzzy cluster analysis. In clustering process, the indexes of power quality comprehensive evaluation are regarded as the characteristic values, and the data points with known power quality level are included in sample data set. According to the principle of "like attracts like" and choosing the optimal threshold, the power quality levels of the sample data points are found, and then the comprehensive evaluation of power quality is realized. Practical effect in two examples proves that the proposed method is effective. In this evaluation, the model is simple and has better expansibility without any personal factor interference. Besides that, it is better to be used for the power quality comprehensive evaluation of regional grid together, which has a good application prospect.关键词
