计及通道因素的城市中压配电网络规划

深入分析了城市配电网电缆通道的特点,在此基础上,提出一种新的配电网规划模型,将通道的投资费用和维护运行费用纳入目标函数,设计并完善了GIS空间数据库结构,采用最短路径法产生初始规划网架,并采用适于复杂系统全局优化搜索的遗传算法进行优化,最终形成候选规划方案。实际算例分析表明,在网络规划中考虑通道成本,使得网络规划结果更具实用性和经济性,对实际的配电网规划也更具指导意义。

Planning of urban mid-voltage distribution network considering cable trench

Based on analyzing the specialties of urban distribution cable trench,this paper presents a new model of distribution network planning,which considers the investment and operation costs of cable trench into objective function. After designing and improving GIS spatial database structure,this paper adopts Shortest Path Method to produce preliminary network,and then uses Genetic Algorithm to optimize the preliminary network. The candidate plans are formed ultimately. The analysis of practical case shows that the network planning considering the cost of cable trench guarantees the practicality and economy of results,and it also has certain guidance for practical network planning.
