配电网快速复电系统关键技术研究

Research on the Key Techniques of Quick Service Restoration in the Distribution Network

随着社会的不断发展进步,人们对供电可靠性提出越来越高的要求,配网自动化作为提高供电可靠性的一种重要技术手段已被广泛应用。目前地区电网的配网自动化系统仍在建设完善当中,通信通道不可靠、终端在线率低造成故障信息不足,以及电网拓扑结构更新不及时等,导致无法准确进行故障定位和故障恢复,已严重影响了地区电网实现快速复电。提出了一种能有效解决上述问题的快速复电系统解决方案,对该方案的几个关键技术分别进行了阐述,并利用IEEE33节点配电系统进行了验证。

With the development of society progress,the public demands a higher level of the power supply reliability,so the distribution system automation has been widely applied. During the construction of the distribution automation system,the goal of quick service restoration has been seriously influenced by the insufficient fault information due to the unreliable of communication channel,the lowonline rate of distribution automation terminals,and the distribution topology error caused by updating timely,so fault section location and service restoration can not properly work. This paper proposes a solution of quick service restoration system which can solve the above problems and expounds its key techniques respectively. Case studies of IEEE33 bus system demonstrate the proposed solution.
