摘要：
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. © 2020 Automation of Electric Power Systems Press.
