Optimal configuration method for power distribution automatic terminal type

Abstract

The invention discloses an optimal configuration method for a power distribution automatic terminal type. A target function of a two-remote and three-remote power distribution automatic terminal optimal configuration model is established, and the target function includes cost generated by adopting a life-cycle period method and comprehensive social benefits generated by reducing of the outage cost; the average power supply availability of a system serves as the reliability constraint condition of the two-remote and three-remote power distribution automatic terminal optimal configuration model, an analytical method is used for conducting reliability assessment, the constraint condition is used for converting a target function through a penalty function method, and a fitness function is formed; the particle swarm optimization is adopted for conducting the optimal solution, adaptive values of particles are calculated, the adaptive value of each particle is compared with the current entity extreme value and the global extreme value, and the optimal entity value and the optimal global value are determined and updated; whether the maximum number of iterations is reached or not is inspected. The optimal configuration method can solve the problem of the number and the position configuration of two-remote and three-remote power distribution automatic terminals.
