输电网接线图增量自动成图算法①

沈自虎,吴淑玮,葛艺晓,张守田(南瑞集团(国网电力科学研究院)有限公司南京南瑞信息通信科技有限公司,南京210003)摘要:输电线网接线图自动成图算法是一个非常复杂的全局优化问题.
它涉及到厂站位置的自动布局和输电线路自动规划两个方面.
本文给出了解决该问题的一种具体思路和算法,将该问题划分为3个部分:首先,利用力导向算法对厂站位置进行初始布局,采用模拟退火算法进行迭代计算,通过并发技术实现引力、斥力系数进行选择,得到代价最小的初始厂站初始布局.
其次,利用A*算法对输电线路进行线路规划,构建了一个线路走向的代价模型,通过代价模型规范线路走向,得到美观的线路布局.
最后,对布局结果评价反馈再布局,将常见的几种布局缺陷通过程序的方式进行消缺,减少人工干预.
同时,本文还对历史线路和新增线路做了处理,使得算法可以实现在不改变历史厂站线路布局的情况下,对新增厂站线路进行布局规划.
通过实验显示,该方法得到的图形结果满足线路规划美观,布局合理,交叉少,拐角少等优点.
