摘要
在分析专用配电网短线路过电流保护现存问题的基础上,提出了一种限流电抗器的优化配置方法.通过增大上下级保护间短路电流差,实现过流保护整定时间的优化.基于粒子群优化算法配置限流电抗器,在满足供电系统稳定性的前提下,实现限流电抗器安装位置以及阻抗值的最优配置.最后,在某煤矿供电系统应用该算法进行配置计算,得到可行的限流电抗器配置方案.
Abstract
Based on analyzing the existing problems of the short line overcurrent protection in special distribution networks,this paper proposes an optimal configuration method for current-limiting reactor.By increasing the short circuit current difference between higher and lower protection,the overcurrent protection setting time is optimized.Particle swarm optimization algorithm is employed to configure current-limiting reactor,achieving the optimal configuration between current-limiting reactor installation location and the impedance value on the premise of maintaining the power system stability.Finally,the configuration calculation by the proposed algorithm in a coal mine power supply system helps formulating the feasible current-limiting reactor configuration scheme.
