摘要

介绍了国内外中压配电网闭环运行方式及其特点;综合考虑可靠性及经济性

建立了配电网从开环运行升级为闭环运行的净收益模型

包括一种简化的中压电缆线路可靠性指标

即系统平均停电持续时间(SAIDI)评估模型;探讨了配电网闭环运行适用范围及实施难度。研究表明

国内现有配电网“闭环设计

开环运行”的供电模式限制了供电可靠性的进一步提升。对于经济发达、负荷密度大、有分布式电源接入以及可靠性要求高的地区

在条件允许的情况下

可考虑采用闭环运行方式(主要为来自同一母线的两馈线自环);该运行方式虽然可能增加供电公司的成本

但能够在提升供电可靠性的同时保证良好的社会经济效益。

Abstract

The closed-loop operation mode and features of medium voltage distribution networks at home and abroad are described. With both reliability and economy considered

a net profit model for upgrading the distribution network from open-loop operation to closed-loop operation is developed

including a simplified evaluation model of system average interruption duration index (SAIDI) for a medium voltage cable feeder. The difficulties and applicable scopes of closed-loop operation are discussed. The study results show: i) further improvement of power supply reliability is impeded because of the existing power supply mode of closed-loop design and open-loop operation for domestic distribution networks; ii) for areas of developed economy

large load density

distributed generation and high reliability requirement

the closed-loop operation mode (mainly one of two feeders from the same bus) can be considered for use conditions permitting. Despite a higher cost for the power supply company owing to the use of the closed-loop operation mode

power supply reliability is improved while good social and economic benefits are ensured at the same time.
