Abstract

Total supply capacity (TSC) is an important evaluation index in distribution network evaluation, and the main measures to improve the TSC of a distribution network are to increase feeders and transformers. This paper improves TSC by optimizing the distribution network structure. Firstly, several typical distribution network power supply modes in China are analysed and their distribution network structures are simplified, including substation structures and feeder connection structures. Secondly, according to different distribution network structures., a certain optimization method is determined. This paper adopts three methods, namely exhaustive method., finite scene optimization method and reasonable judgment comparison method., to determine the specific distribution network connection schemes and the “N-1” transfer schemes. Finally, structures of several examples are optimized, and their TSCs are calculated. Through the comparison analysis, the effectiveness of the distribution network structure optimization methods proposed are verified.

基于总供电能力提高的中压配电网结构优化

总供电能力(TSC)是配电网评价中的一个重要评价指标，提高配电网总供电能力的主要措施是增加馈线和变压器。本文通过优化配电网结构来改进TSC。首先，分析了国内几种典型的配电网供电方式，并对其配电网结构进行了简化，包括变电站结构和馈线连接结构。其次，根据不同的配电网结构。，确定了一定的优化方法。本文采用三种方法，即穷举法。、有限场景优化法和合理判断比较法。，确定配电网的具体接线方案和“N-1”输电方案。最后，对几个算例的结构进行了优化，并对其tsc进行了计算。通过对比分析，验证了所提出的配电网结构优化方法的有效性。
