中压配电网网架接线模式研究与应用
|
摘要
一流城市需要一流配电网。介绍了国际上典型一流城市中压配电网结构模式,总结归纳了中压配电网网架结构在提高供电可靠性、减少停电时间上的作用。对比分析了现状中压电缆网大分支网架结构的改造方式,总结提炼并形成适用于福州地区建设世界一流城市配电网的中压电缆网网架结构,提出双环网、单环网的典型接线模式,包括主干线路和分支线路的接线形式,并进行了可靠性计算和论证,用以指导福州地区世界一流城市电网建设。
World-class cities need world-class urban distribution networks. This paper introduces the structure mode of medium voltage distribution network in typical first-class cities in the world,and summarizes the role of the grid structure of medium voltage distribution network in improving power supply reliability and reducing power outage time. The transformation mode of the current large branch network structure of the medium voltage cable is compared and analyzed in this paper,and the medium voltage cable frame structure which is suitable for the construction of the world-class urban distribution network in Fuzhou area is summarized and formed. The typical connection modes of the double ring network and single ring network are put forward,including the connection forms of the main lines and the branch lines,and reliability calculation and demonstration are carried out to guide the construction of the world-class city power grid in Fuzhou.
