玉柳全电缆电力贯通线无功补偿配置及优化分析
The compensation allocation and optimization analysis of high-voltage transmission line of Yuliu power cable

以兰新客运专线玉柳段为例,建立全电缆贯通线的潮流模型,提出利用遗传算法对无功容量配置进行优化,并利用Matlab对该线路分别采用现有补偿容量配置和优化后补偿容量配置在不同负荷率下进行仿真,并对比2种补偿容量配置的补偿效果。研究结果表明:优化后的无功容量配置方案,不仅降低了配置容量,而且改善了首端功率因数及线路各节点电压。
Yuliu section of Lanzhou-Xinjiang passenger-dedicated Line was taken as an example. The load model of the high-voltage power line along the railway was established by using the genetic algorithm to optimize the reactive power capacity allocation. The Matlab program was used in the line in combination with the existing compensation capacity allocation and optimized configuration for simulations under different load rate, and the effects on two type of allocation were compared. The results indicate that the optimized reactive power capacity allocation scheme not only reduces the configuration capacity, but also improves the power factor of the head end and the voltage quality of each node of the line
