基于因子分析的电气化铁路电能质量影响综合指标研究

Study on Integrated Impact Indices of Electrified Railway Power Quality Based on Factor Analysis

在大量电气化铁路电能质量监测点的统计数据基础上,运用因子分析将相关性很高的多个单项电能质量指标提取并命名为综合电流因子、综合电压工频因子和综合电压低频因子三个互不相关的综合电能质量指标因子。研究结合某省网公司电气化铁路监测数据计算各监测点的综合因子得分,说明综合指标的合理性和实用性。

On the basis of abundant statistical data from electrified railway power quality monitoring points, three unrelated integrated power quality indicators are extracted from multiple highly relevant individual power quality indices using factor analysis, and they are respectively named as integrated current factor, integrated voltage power frequency factor and integrated voltage low frequency factor. Monitoring data from the electrified railway of a certain provincial grid is used to calculate integrated factor scores for each monitoring point, and to show the reasonability and practicability of the integrated indices.
