摘要(Abstract)：

针对现行供电可靠性指标体系无法准确反映用户实际用电可靠性的问题,根据用电可靠性概念建立了评价指标体系,并设计一种基于改进熵权法的配电网用电可靠性综合评估方法。首先,根据用电可靠性概念和评估需求,从用户侧指标和对比指标2个维度建立用电可靠性指标体系。7个用户侧指标从供电持续性及电能可用度2个方面反映用户实际用电可靠性水平,2个对比指标旨在反映中低压用户之间线路的可靠性水平;然后综合考虑可靠性评价要求及指标特性建立一种综合评估方法,通过改进熵权法初步获得指标权重,依据突出不合格指标的"越值惩罚"原则确定最终权重矩阵,加权求和得到评估对象的综合评价值。最后,通过实例分析验证该指标体系及综合评价方法的有效性。
