中低压配电网典型电压越限分类与界定
|
摘要
介绍某地区负荷增长迅速、供电半径普遍较长、电压越限现象比较突出的情况。对输电网、配电网、用户三个层面的调研,并对电压越限成因进行原理分析,将其影响原因分为三类:上级电网运行与控制方式、网架结构、负荷特性。但中低压配电网电压越限问题十分复杂,成因相互耦合。本文从高电压等级向低电压等级对几种西双版纳地区中低压配电网典型电压越限现象进行界定,找到现象成因的主导因素,对下一步的综合治理方案具有指导意义。
Somewhere have many typical features of power supply, such as the rapid-increasing load, the general-long power supply radius, and prominent issues of voltage limit violation. Through the extensive-research relevant to transmission network, distribution network, and corresponding users in Xishuangbannam, as well as studying the principle of voltage limit violation issues, the corresponding reasons tend to be divided into three categories: power grid operation and control mode, grid structure, and load characteristics. However, the reasons of voltage limit violation issues are quite complicated, and they are mutual coupling with each other. This paper defines the typical phenomenon of voltage limit violation issues from high to low voltage level in the case of Xishuangbanna, dig the corresponding leading factor. All of the above are expected to offer the significant guidance with respect to building the future treatment plan.
