摘　　要：在分析输电线路中TCSC与SVC的设计所存在的相互矛盾的基础上,针对牵引供电系统中动态并联补偿装置与串联补偿装置的协调控制问题进行研究.在节能的前提下,得出了各补偿装置补偿容量的优化控制策略,并提出了一种动态并联补偿装置的定性定量控制技术.该控制系统有效地提高了补偿的速度和精度,并具有良好的跟踪负载变化的性能,对我国电气化铁路的改造具有重要意义.Based on the analysis on the contradiction between the designing of thyristor controlled series capacitor（TCSC） and static var compensator（SVC） in same circuitry,how to coordinate control dynamic parallel capacitor compensation and series capacitor compensation in power supply system of train＇s traction is studied.For saving energy,an optimal control strategy about capabilitys of compensations and a qualitative-quantify control way for dynamic parallel capacitor compensation are advanced.The system can improve effectively the rate and precision of compensating,and has a fine perfermance to change the compensation when load changes,so it has great significance for making over our electrization railway.
