摘要随着电网结构日益复杂，电网合理的分区分层已经成了电力行业的重要研究内容。针对已经进行分区运行的电网，当出现不同电压等级的设备如主变以及线路过载的情况，本文给出了对电网过载负荷进行转供的处理方案。对应具体情况，可以采用负荷转供、电磁环网解合环等以线路投切为核心的动态分区技术来减缓或解决设备过载问题。本文进一步选取了电网的几种重要指标建立了分区电网评价指标体系，对不同的动态分区方案进行综合评价，从而得到了适用的具体方案。通过具体的算例表明，该动态分区方案可以解决电网设备过载问题，保证电网安全稳定运行。84371

Title  Auxiliary decision making of equipment overload based on dynamic partitioning technology                   

Abstract With the increasing complexity of power grid structure, the reasonable partition layer of power grid has become an important research content in the power industry。 In view of the power grid which has already been carried out in the area, when there are different voltage levels of equipment such as the main transformer and the overload of the line, this paper presents the processing scheme of the overload load。 Corresponding to the specific circumstances, using the load transfer, the electromagnetic loop network solutions and so on line as the core of the dynamic partitioning technology to slow down or solve the problem of equipment overload。 In this paper, several important indicators of the power grid are selected to establish the evaluation index system of the regional power grid, and the comprehensive evaluation of different dynamic zoning plan is carried out。 Through the concrete example, it shows that the dynamic partition scheme can solve the overload problem of power system equipment, and ensure the safe and stable operation of power network。

Keywords  load transfer  the dynamic partitioning technique  the dynamic zoning plan
