摘要: |
为了解决配电网馈线自动化中不同网络结构、不同供电可靠性需求下配电终端的优化配置问题,对配网供电可靠性与馈线自动化终端配置的敏感性进行了分析。采用故障模式与后果分析法,提出了基于配网可靠性发展目标的配电终端优化配置方法。在综合考虑技术性、经济性、可拓展性的基础上,分析了无配电终端、全“二遥”终端配置和“二遥”、“三遥”终端混合配置三种模式下,配电网典型结构的线路故障停电时间和配电网平均供电可用率;得到了配电网平均供电可用率和配电终端优化配置的通用计算方法。算例验证了研究方法的合理性和实用性。 |

Abstract: |
To optimize the allocation of remote terminal unit of distribution automation system, which meets the requirement of different network structures and different power supply reliability, the sensitivity between power supply reliability and the number of feeder terminal units (FTUs) is analyzed. The method of middle voltage distribution network FTUs optimal configuration are proposed based on the consequences of failure mode and effect analysis. On the basis of considering technical, economic and scalability factors, line failure outage time and average service available index (ASAI) are analyzed in three cases: line without configuration of terminal unit, line with configuration of monitoring terminal unit only and line with mixed configuration of monitoring terminal unit and controlling terminal unit. The generic expression of ASAI is deduced, as well as the number of FTUs. Example demonstrates the rationality and practicality of research methods. |
