Intelligent planning of medium voltage distribution network based on power supply model—— automatic routing of triangle power supply model with triple contact

为了使供电模型理念更好地融入到实际的电网规划工作中,对中压配电网三角形三联络供电模型进行了自动布线研究。首先针对三分段三联络供电模型的结构特点,按照"单辐射-单联络-三分段三联络"的构建顺序建立了自动布线的规划模型,然后应用遗传算法对供电模型进行整体优化,最后通过算例验证得到了全局最优的布线结果。规划方案符合配电网规划的实际特点,证明了该算法的可行性与实用性,对基于供电模型的中压配电网规划具有一定的指导意义。

In order to make a better combination of the power supply model concept and the actual planning work, this paper makes a research on automatic routing of distribution network based on triangle power supply model with triple contact. Firstly in view of the constitution of power supply model with triple segmentation triple contact, according to the sequence of ＂single radiation- single contact- triple segmentation triple contact＂, a planning model of automatic routing is established. Next the power supply model is optimized from the global perspective by using the genetic algorithm. Finally through the sample verification, the global optimum routing results are obtained, and the planning scheme conforms with the actual characteristic of the distribution network planning. Thus the feasibility and practicality of the above mentioned algorithm are proved. It is also helpful to direct the distribution network planning based on the power supply model to some extent.
