摘要：

随着城市开发建设进程的加快以及多元化负荷及电源接入，对城网的建设要求也随之增加，城市

核心区双环网建设以来，电网可靠性有了显著提升。文章通过对主干网架、分支网架、用户接入3种典

型模式下双环网建设的探索，明确城区未来配电网发展方向和布局，为智慧配电网建设做好基础工作。

Abstract:

With

the

acceleration

of

urban

development

and

construction

process

，as

well

as

the

integration

of

diversified

loads

and

power

sources,

the

construction

requirements

of

urban

network

have

also

increased.

Since

the

construction

of

double-loop

network

in

urban

core

area,

the

reliability

of

power

grid

has

been

significantly

improved.

This

paper

explores

the

construction

of

double-loop

network

under

three

typical

modes:

trunk

network,

branch

network

and

user

access.

The

development

direction

and

layout

of

urban

distribution

network

in

the

future

are

defined,

so

as

to

do

a

good

job

for

the

construction

of

smart

distribution

network.

随着现代电力系统的不断发展，供电可靠性越表1城市核心区双环网建设原则

来越受到关注。双环网作为一种常见的网架结构，指标参数

具有较高的可靠性和稳定性，被广泛应用于城市网络网架结构双环网

核心区的中压网架中。结合城区双环网电网现状，方面运行方式开环运行

以提升供电可靠率为目标，采用“以网架优化
