摘要：

智能化是配电网发展的基础,也是配电网发展的主要方向之一,而分布式电源与多元化负荷的接入势必会对配电网可靠性产生影响。重点分析分布式电源与多元化负荷对配电网供电可靠性所带来的影响,归纳和研究针对配电自动化介入对其可靠性提升的策略及方法。在配电自动化介入后,搭建不同模式下可靠性的计算模型,并基于层次分析法和FMEA故障模式后果分析法对可靠性计算结果进行成效评估。针对含分布式电源与多元化负荷的配电网可靠性计算方法,进一步阐述需要考虑的问题及为推广应用所需考虑的标准化方向。

关键词: 分布式电源, 多元化负荷, 配电网可靠性, 配电自动化

Abstract:

Intelligentization is the foundation of the development of the distribution network and one of the main directions of the development of the distribution network.The access of distributed power sources and diversified load are bound to have an impact on the reliability of the distribution network.The impact of distributed power sources and diversified loads on the reliability of distribution network power supply was mainly analyzed.The strategies and methods to improve rebiability of distribution automation intervention were summarized and studied.After the intervention of distribution automation,the calculation model of reliability in different modes was built and the effectiveness of the reliability calculation results was evaluated based on the analytic hierarchy process and the FMEA failure mode consequence analysis method.Finally,it elaborated on the further issues that need to be considered in the reliability calculation method of the distribution network with distributed power sources and diversified loads,and the direction of standardization for popularization and application.

Key words: distributed generation, diversified loads, distribution network reliability, distribution network automation
