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
