| 摘 要： | 高可靠性主动配电网的基本特征是高可靠性，以及具备灵活的网架重构能力和源-网-荷协调互动能力。然而，传统闭环设计开环运行的配电网，及其基于配电自动化和电流级差保护的保护控制方法已无法满足这一要求。为此，提出了涵盖配电网拓扑结构、广域保护测控体系和配电终端选型要求等方面在内的高可靠性主动配电网供电模式及其工程实现方案，通过闭环运行的网架结构、不停电故障隔离，以及高度可扩展性的配电终端，实现主动配电网的高可靠性和高灵活性。基于实际工程的案例分析表明，所提的方案具有充分的工程的有效性和可实施性，为高可靠性区域配电网的规划建设提供了方法支持。

| Abstract: | High reliability active distribution network is based on strong network frame, and has ability of flexible network reconstruction and ability of coordinating and interacting among power source, grid and load. However, traditional distribution network are operated in open loop and designed in closed loop, and its protection method which are based on distribution automation and current differential protection can no longer meet the requirements for high reliability active distribution network. In this article, a high reliability distribution network model and its construction implementation plan is put forward, which includes distribution topology, Wide Area Measurement and Control System and requirements for distribution network automation terminal device type and so on. This model and plan offer a planning and construction support method for high reliability distribution network. |
