电气化铁路动态无功补偿方法研究

Research on Dynamic Reactive Power Compensation Method for Electrified Railway

基于分析某电气化铁路货运专线的实测数据,通过Matlab仿真验证,比较了各种补偿改造方案对电能质量的影响。找出了在牵引变电所两供电臂加固定补偿在轻负荷侧加动态补偿为该货运专线电能质量的最佳补偿效果方案,对合理选择牵引变电所无功补偿容量和提高补偿效果具有一定指导作用。

Based on the analysis of measured data in the special freight line,the designed compensation scheme is simulated by Matlab.And various compensation scheme effect on the power quality is compared.Then we find out the best compensation for the effect of the program in traction substation power quality is the installation of fixed compensation device in supply arm plus the dynamic compensation device in the light load side,which has certain guiding role on the reasonable selection of reactive compensation in traction substation capacity and improves the compensation effect in the special freight line.
