一种有限互联的双环式电缆配电网结构

A Limited-interconnection Structure of Double-loop Cable Distribution Network

双环式电缆配电网由于是2个完全互不联络的单环式结构组成的,负荷倒换转供时存在对侧电源单一受限的缺点,而主观无序互联负荷倒换转供时又存在运行方案选择混乱、降低工作效率的缺点,因此提出一种有限互联的双环式电缆配电网结构,提供不停电作业友好网架环境,提升电缆线路负载率和供电可靠性,重点介绍该电网结构的实施方式和应用优势。

Currently applied double-loop cable distribution network is composed of two completely isolated single-loop structures.This framework is confounded owing to disadvantages including limited single opposite-side source for supply alternation by load switching,and confused operation scheme and inefficiency for supply alternation with disordered load switching.Therefore a limited-interconnection double-loop cable distribution network structure is reported in this paper along with its implementation method and applicative advantages,aiming at providing a friendly grid environment for uninterrupted operation and improving line load rate and supply reliability of cable lines.
