| 摘要: |
| 针对传统供电可靠性定义中未对停电后的负荷恢复过程(LRP)进行有效计及的问题，提出考虑LRP的配电网用电可靠性评估指标与方法。对配电网用电可靠性进行定义，对LRP责任区分进行阐明，并在此基础上从供电持续性、LRP影响、全局性和对比性4个维度建立配电网用电可靠性评估指标体系，其中重点从结果、过程及影响范围特征上对LRP影响进行描述，并提出全局性指标和对比性指标以满足实际工程中的单指标评估。对于供电持续性及LRP影响，考虑指标间相关性提出网络层次分析法、改进相关性权重法和改进逼近理想点排序法相结合的综合评估模型，以对用电可靠性进行综合评估。实例分析表明，所提指标与方法能对用户受到的停电影响进行精细化描述。 |

| Abstract: |
| Aiming at the problem that the LRP(Load Recovery Process) is not taken into account effectively in the traditional definition of power supply reliability, the reliability assessment indexes and methods of distribution network for power consumer considering LRP are proposed. The definition of distribution network reliability for power consumer is given, and the LRP responsibility distinction is clarified. On this basis, the comprehensive assessment index system of distribution network reliability for power consumer is established from the four dimensions of power supply continuity, LRP impact, global performance and comparability. The LRP impact is described from the results, process and impact range characteristics, and the global and comparative indexes are proposed to meet the requirements of single index evaluation in practical enginee-ring. Considering the influence of power supply continuity and LRP, considering the correlation between indexes, a comprehensive assessment model combining analytic network process, improved criteria importance through intercriteria correlation and improved technique for order preference by similarity to an ideal solution is proposed to comprehensively assess the reliability for power consumer. The case analysis shows that the proposed indexes and methods can describe the impact of power outage on users in detail. |
