Abstract
Using the power quality real-time monitoring data of a certain provincial grid and the parameters of the grid and traction load, individual power quality indicators at each monitoring point are statistically calculated. Based on factor analysis and statistical data, three integrated power quality factors are constructed and defined, namely integrated current factor, integrated voltage power frequency factor and integrated voltage low frequency factor. With these factors, the power quality comprehensive score and fuzzy C-means clustering for each monitoring point is calculated, and the power quality status of those monitoring points in the study period is classified as five categories of"excellent", "good", "fair", "poor" and "worse". Consistent reference results are obtained on the same platform, and dynamic evaluation of electrified railway monitoring points is achieved. The research provides not only the basis for future unified management of power quality, but also a reference for future planning and governance of power quality.关键词
