Full-cable medium voltage distribution network planning based on incremental shortest path method

电缆化供电是城市中压配电网供电的发展趋势。提出一种实用的基于增量最短路径法的全电缆中压配电网络主干网架规划方法,考虑了电缆通道约束以及城市规划约束,将全网整体优化分解为电源供电分区的电缆线路规划和分区间线路联络规划两部分,利用增量最短路径法规划电源供电分区的电缆供电线路,应用最佳匹配算法完成分区间线路联络。通过一实际算例验证了所提方法可应用于全电缆中压配电网的网络新建规划和扩展规划。

Cabling reconstruction has become the development trend for urban medium voltage distribution network power supply. A practical planning method for the backbone network of full-cable medium voltage distribution network is proposed based on the incremental shortest path method considering the cable channel constraints and urban planning constraints. The overall optimization of the whole network is divided into two parts: the cable line planning of power supply zones and the line connection planning among power supply zones, and the two parts are completed by the incremental shortest path method and the best matching algorithm respectively. An actual example shows that the proposed method can be applied to the network construction and expansion planning of the full-cable medium voltage distribution network.
