配网故障指示器最优配置研究

为了实现故障指示器的经济性配置,提出一个关于故障指示器最优配置的目标函数。从经济性的角度出发,研究最佳的故障指示器安装位置和安装数目,期望在缩短故障定位时间的基础上,最大程度地降低设备安装和运行成本,达到经济上的最优化。应用免疫算法对该目标函数进行求解,并对一个小型网络进行故障指示器配置分析,进行算法仿真。仿真结果表明,从经济性的角度分析故障指示器的配置问题是可行的,故障指示器应该安装在合适的地方才能实现最大效益的利用。

Optimal configuration of fault indicator in distribution network

To realize the economic configuration of fault indicator, this paper proposes an objective function on its optimal configuration. Its number and installation location both affect the fault interruption time. On the basis of shortening fault location time, the cost of equipment installation and opeation will be lowered at utmost. This paper takes use of the immune algorithm to solve the objective function and analyzes the fault indicator configuration of a small-scale network and makes algorithm simulation. Simulation results show that it is feasible for analyzing fault indicator configuration from the aspect of economy, and fault indicator should be installed at the suitable locations so as to achieve the maximal benefit.
