摘要
为了实现故障指示器经济性配置,本文以降低经济损失为目的改进了已有的配电网故障指示器最优配置目标函数。以一个小型农村10k V配电网络为例,阐述了配电网支路对工作人员寻找故障点平均时间的影响,从而简化了故障指示器配置的方案。在此基础上应用遗传算法对该10k V配电网的目标函数进行求解。Matlab计算结果表明:对于一个网架结构固定的配电网络,合理配置故障指示器有利于降低故障停电带来的经济损失;在故障指示器最优配置基础上增设故障指示器数目有利于降低寻找故障点的平均时间。
In order to realize the economic configuration of fault indicator.This paper improves the objective function of the optimal configuration principle of the existing distribution network fault indicator with the aim of reducing the economic loss. This papertake a small rural l OkV distribution network as an example, explainedthe influence of the branch of the power distribution network on the average time of finding the fault point, so the scheme of fault indicator configuration is simplified. On this basis, taking use of the genetic algorithm to solve the objective functionof the lOkV distribution network.The results show thatthe reasonable configuration of fault indicator is beneficial to reduce the economic losses caused by the failure of the fault. On the basis of the optimalconfiguration of the fault indicator, adding the number of fault indicator is good to reduce the average time to find the fault point.
