摘　　要：馈线开关监控终端是重要的配电自动化终端设备,数量众多、安装分散,对数量和位置进行优化配置有利于提高配电自动化系统的可靠性、经济性。对此,提出了一种数量规划与位置优化分步进行的FTU配置方法:首先从经济性、可靠性两方面出发,基于非线性整数规划的方法进行FTU的数量优化配置,并借助遗传算法进行求解;其次考虑馈线开关附近的不同负荷类型及数量,兼顾不同类型FTU的功能特性,进行FTU的位置优化配置,从而达成配电自动化系统中FTU配置的最优方案。实际算例验证了方法的可行性。As FTU, an important distribution terminal unit, is installed dispersedly and used in a large amount, optimal configuration of its quantity and position is helpful to the improvement of the reliability and economical efficiency of the distribution automation system. In this background, this paper presents an FTU configuration method whereby quantity planning and positional optimization are made in separate steps. Firstly, considering both economical efficiency and reliability, FTU quantitative optimization configuration is made in a method based on nonlinear integer programming, and a solution is made with the help of genetic algorithm. Secondly, considering types and amount of different loads near the feeder switch as well as functional characteristics of different types of FTU, we make FTU positional optimization to find an optimal FTU configuration scheme in the distribution automation system. Practical calculation cases verify the feasibility of the proposed method.
