基于空间GIS和Tabu搜索技术的城市中压配电网络规划

该文结合中压配电网空间数据结构的特点,设计了适合于配电网络规划的GIS空间数据库和规划模型.在此基础上考虑到线路沿街道布局的特点,采用了变长度的符号编码策略来表示线路的结构,并用最短路径法形成初始网架.作者采用具有禁忌搜索思想的TS算法对初始网架进行了优化.通过对实际算例的分析,发现以空间GIS为平台将网络规划问题和地理环境紧密联系起来,并以TS算法指导搜索过程,是配电网络规划工作中一个切实可行的方法.

URBAN MEDIUM-VOLTAGE DISTRIBUTION NETWORK PLANNING BASED ON SPATIAL GIS AND TABU SEARCH

Considering the features of spatial data structure in medium-voltage distribution network, the GIS spatial database and planning model suitable to distribution network planning are designed. On this basis and according to the property that the distribution lines are arranged along the streets, the line structure can be represented by length-varying chromosome encoding strategy and the preliminary radial network is formed by the shortest path method. The preliminary network is optimized by Tabu search algorithm. By means of the analysis on actual calculation examples, a practical method for distribution network planning is discovered in which the spatial GIS is used for platform, the distribution network planning is tightly correlated with geographical environment and the search process is guided by TS algorithm.
