| 摘 要： | 该文运用GIS技术将负荷点的地理坐标转化为屏幕坐标，并在屏幕上显示，根据屏幕上负荷的分布密度情况，通过人机对话方式将规划区域划分成几个小区域(分块区域)。首先对每个分块区域利用最小二乘法确定初始主干线，在此基础上对该区域的负荷点按照最短路径法进行连接，形成初始网架；根据目标函数的要求不断修正主干线及相应的负荷连接，实现了每个分块区域的最优网架；将每个分块区域的优化网架连接，形成该区域的优化网架。该方法将网架优化理论与GIS技术紧密结合，并将复杂问题分解成简单问题。实例规划结果表明，该优化方法智能、快速、有效。

| Abstract: | The geographic coordinates of loads are converted into screen coordinates to show on the screen by GIS technology, according to the power load distribution density condition, the plan area is divided into several small areas(partial areas) by man-machine conversation. First, the initial main trunk line is formed in every partial area making use of least square method. On the basis of that, the power loads of the area are linked according to the shortest path method, thus an initial network frame of every partial area is formed. Then the initial network frames are amended continuously to form the optimal network frames with the least aim functions. Last, an optimal network frame of the whole area is formed by linking the optimal network frames of all partial areas. The method combines optimizing theory with GIS technology closely, and decomposes complex problem into simple problems. The real example planning result indicates that the planning method is intelligent, fast and effective. |
