摘要

近年来，故障指示器凭借其接入灵活性和经济性被广泛应用于配电网故障定位中。然而全覆盖式地故障指示器安装配置方案投资成本高，规划方案不精益。文中提出一种基于故障信息变量的配电网可靠性评估模型；进一步给出一种基于混合整数线性规划的可靠性约束的配电网故障指示器优化布点方法，将可靠性指标作为约束放入优化模型中，在满足可靠性要求的前提下降低故障指示器的投资维护成本。基于IEEE 53节点系统的算例仿真结果表明，所提方法兼顾了故障指示器布点的可靠性与经济性，可以精确获得不同可靠性要求下的布点方案。

Abstract

In recent years

fault indicator is widely used for fault location of distribution network because of its access flexibility and economy. However

the full-coverage installation configuration scheme of fault indicators has high investment cost

and the planning scheme is not lean. In this paper

a distribution network reliability assessment model based on fault information variables is proposed

and an optimal placement method of fault indicators in distribution network based on reliability constraints and mixed-integer linear programming is proposed. The reliability indices are put into the optimization model as a constraint to reduce the investment and maintenance cost of fault indicators on the premise of meeting the reliability requirements. The simulation based on IEEE 53-bus system shows that the reliability and economy of fault indicator placement are taken into account in the proposed method

and the placement schemes under different reliability requirements can be accurately obtained.
