介绍了牵引供电负荷补偿的目的及负荷补偿器的技术条件,分析了无功补偿应用现状,结合神华大准铁路实际运行中存在接触网末端电压过低的问题,研究利用瞬时无功补偿来控制功率剧变,其基本思路是通过建立供电系统网络方程,对影响供电系统品质的因素进行比较分析,以期达到对无功的实时动态补偿控制。
The purpose of load compensation of traction power supply and the technical conditions of load compensator are introduced. The status quo of application of reactive power compensation is analyzed. Combined with the problem of too low voltage at the end of catenary in actual operation of Shenhua Dazhun railway, the instantaneous reactive power compensation Power drastic changes, the basic idea is through the establishment of power supply system network equations, the factors that affect the quality of power supply system for comparative analysis, in order to achieve real-time dynamic reactive power compensation control.
