摘　　要：为提升有功功率占比量,控制无功功率数值水平,实现对铁路无人配电所内传输电信号的高效利用,提出了铁路无人配电所无功补偿参数变异粒子群优化算法。根据无功补偿型拓扑结构的连接形式,求解瞬时配电功率指标,并以此为基础,计算电信号偏移量,完成铁路无人配电所的无功补偿参数寻优。按照粒子群优化权限标准,确定差分变异系数的取值范围,联合相关指标参数,调整关键配电参数,完成对无功补偿参数变异粒子群的优化处理。对比实验结果表明,在优化算法作用下,有功功率占比超过了90%,而无功功率占比却始终小于5%,符合高效利用铁路无人配电所内传输电信号的实际应用需求。In order to improve the proportion of active power,control the level of reactive power value,and realize the efficient use of the transmitted electrical signals in the railway unmanned distribution substation,a mutation particle swarm optimization algorithm for reactive power compensation parameters of the railway unmanned distribution substation is proposed.According to the connection form of reactive power compensation topology,the instantaneous distribution power index is solved,and on this basis,the electric signal offset is calculated to complete the optimization of reactive power compensation parameters of the unmanned railway distribution substation.According to the standard of particle swarm optimization authority,determine the value range of differential variation coefficient,and combine relevant index parameters to adjust key distribution parameters to complete the optimization of reactive power compensation parameter variation particle swarm.The comparative experimental results show that under the action of the optimization algorithm,the proportion of active power is more than 90%,while the proportion of reactive power is always less than 5%,which is in line with the practical application requirements of efficient use of the transmission of electric signals in the unmanned railway distribution station.
