[摘 要] 随着城市化进程的加快,城区负荷密度持续上升,在这种情况下为了提高对各个用户的供电服务水平,就必须改良配网供电方式,其中配网规划是一项艰巨的任务。采用网格化的配网规划模式,实行网格内针对性的供电,这样不仅能提高供电质量,还能为不同类型的用户提供适合的服务。文章重点分析了配网网格化规划的思路、流程和原则,以及具体的网格化配网规划策略。

Research on Planning Strategy of Grid Distribution Network Based on the Continuous Increase of Load Density
Ou Jun-yuan
[Abstract]Due to the acceleration of urbanization, the urban load density continues to rise. In this case, in order to improve the level of power supply service to various users, it is necessary to improve the power supply mode of the distribution network. Among them, the distribution network planning is a difficult task. The grid-based distribution network planning mode is adopted to implement targeted power supply within the grid, which can not only improve the quality of power supply, but also provide suitable services for different types of users. This article focuses on the analysis of the ideas and principles of grid-based distribution network planning and specific grid-based distribution network planning strategies.

以往的配网规划都是参照特定技术规范进行的,其中出现了管理无序、混乱的问题,而且和城市的规划与建设不相协调、不相融。随着配网系统建设规模的持续扩大,负荷密度持续上升,配网系统需要采取网格化的规划方案,缩小管理范围,从而达到区域内供电管理,实现精细化管理的目标。
1 配网网格化规划的思路、流程和原则
1.1 配网网格化规划的思路
配网网格化规划主要是采用网格化的负荷密度预测方法,也就是把需要规划的区域根据区域内地块特征、性质、负荷特点等来细致划分,细化为若干负荷区块,根据负荷性质来提取负荷点位,实施统一聚合处理,生成区块整体负荷,根据区块负荷的现实情况来形成配网建设工程的具体规划方法。空间布局:具体来说,是以被规划区域的空间用地规划作为依据,科学地预测负荷密度,划分供电功能分区,形成网架结构方案。……
