摘要：电网投资对线损率的影响缺少量化分析，传统的台区降损评价未充分考虑变压器损耗和台区间的
损耗转移，文章基于同期线损
+
理论线损的方式，捆绑计算台区线损和变压器损耗，评价增设台区前后
的综合线损率变化情况，量化技术降损成效，为降损潜力分析、线损率预测提供参考。

Abstract:The
impact
of
power
grid
investment
on
line
loss
rate
lacks
quantitative
analysis.
Traditional
evaluation
of
loss
reduction
in
transformer
areas
does
not
fully
consider
the
transformer
losses
and
loss
transfer
between
transformer
areas.
This
paper,
based
on
the
method
of
synchronous
line
loss
and
theoretical
line
loss,
calculates
the
line
loss
and
transformer
loss
of
transformer
areas
in
a
bundled
manner,
evaluates
the
changes
in
the
comprehensive
line
loss
rate
before
and
after
the
addition
of
transformer
areas,
quantifies
the
effectiveness
of
technical
loss
reduction,
and
provides
a
reference
for
loss
reduction
potential
analysis
and
line
loss
rate
prediction.
