摘　　要：基于电力系统电能质量指标评估的现状,通过分析现行三种单一评估方法和三种组合评估方法,提出了一种基于融合相似性特征与差异性特征的电能质量组合评估方法,降低了单一评估方法的泛化误差,实现了对电力系统电能质量实际状态更拟合化的综合评估,为电力系统电能质量评估方法研究提供了一种新思路。Based on the current situation of power quality index evaluation of power system,a combined power quality evaluation method based on fusion similarity characteristics and difference characteristics is proposed by analyzing the current three single evaluation methods and three combination evaluation methods.This method reduces the generalization error of a single evaluation method,realizes a comprehensive evaluation of the actual state of power quality of the power system,and provides a new idea for the research of power quality evaluation method of the power system.
