配电网运行区域的划类分析

Analysis of Distribution Network Movement Region Delimitation

配电网运行时的电能损耗在整个电网的网损中占有很大比重,因此,搞好配电网负荷管理和技术改造,可以降低网损、减少成本、提高经济效益。从配电网的网损与网损率的解析计算入手,分析了配电网运行中电能损耗的特殊规律,提出了经济运行负荷Pec与最小网损率ΔAmin%两个概念,导出了计算公式,给出了划分配电网经济运行区域[P]ec解析方法,阐述了各类运行区域的特点及管理要点,对配电网的降损节电,提高经济运行水平和搞好配电网的技术改造具有一定的指导意义和现实意义。

The electrical energy loss of the distribution network movement holds the very great proportion in the entire electrical network. So, doing well the distribution network load management and the technological transformations, can reduce the net damaging and cost and enhance the economic efficiency. This paper analyzes the special rule of he electrical energy loss in the distribution network movement from the distribution network net and the netdamaging rate analysis computation, proposes the two concepts of economical movement load P _ ec and the smallest netdamaging rate Δ A min%, derives the formula, gives the method of deriving distribution network economy movement region P _ ec , explains the characteristic and the management main point of each kind of movement region, It has the important guiding sense and the practical significance to raise the economical movement level and technological transformations of electrical network.
