配电网负荷转带方法的研究

Study on service restoration method in distribution networks

提出一种在电力线路故障后，为受故障影响停电的非故障区段负荷恢复供电的方法。供电网络用供电树表明，从线路的故障点开始，以网络的拓扑分析为基础，用遍历供电树的方法，可寻找所有可能的恢复供电方案。通过计算损耗和过负荷，对所有可能的恢复供电方案进行比较，最后确定优化的负荷转带方案。最后，用一实例验证了文中的方法。

This paper proposes a method to determine the service restoration strategies for affected load due to fault on a feeder line. The aim is to determine the switchers that will be put into operation after a fault. An algorithm based on network topology is proposed, and all possible service restoration strategies are found by traversing power supplying trees. The final three strategies are selected by calculating and comparing voltage loss and over-load of all the strategies. An example is also given to testify the method.
