深圳电网负荷分类及构成分析

Analysis on Shenzhen Grid Load Classification and Composition

摘要: 深圳作为我国的经济特区、全国性经济中心城市和国际化城市，正在进行产业结构优化调整，电网负荷特性也在随之变化。结合深圳电网实际情况，对全网各10 kV馈线的负荷分类情况、分类负荷大小进行了调查和统计。并结合2012年夏大方式下电网拓扑结构，运用容量加权平均方法，最终确定网内各220 kV变电站110 kV侧的负荷构成特性。最后通过归纳分析，确定深圳电网分类负荷的基本特性。

Abstract: To meet the high location of special economic zone, national economic center city and international city, Shenzhen is carrying out its industrial structure optimization adjustment. In this case, power load characteristics of Shenzhen grid are changing accordingly. In this paper, load classification and classified load value of 10 kV feeders of the current Shenzhen grid are investigated and organized. Volume-weighted average method is used to calculate load composition of the grid in top loading operation mode topological structure. By summing up the calculation results, classified load essential properties of the Shenzhen grid are given.
