摘要
为满足新一代高速列车试验,保证牵引变电所供电质量,消除负序电流影响,充分发挥电力系统的输电能力,本文对采用牵引变压器与动态平衡补偿装置(TSC+TSR)结合的牵引供电系统展开研究。在介绍当前试验系统存在问题、三相平衡补偿方案设计及工作原理的基础上,研制开发了TSC和TSR结合的动态无功平衡补偿装置,实现了良好的补偿电流,能无级跟踪牵引负荷的变化,保证了在全负荷范围内三相母线电流的完全平衡对称,提高了系统的安全性能,适应于三相和单相牵引变压器系统。
In order to meet the test of the moter trainset, guarantee the power quality of traction substation, eliminate the effect of negative sequence current, and give full play to the transfer capability of electric power system, the traction transformer and dynamic balance-compensation equipment （TSC＋TCR） are cooperated on the traction power system, which is studied in this paper. After the introduction of present problems in test system, the scheme design of three-phase balance-compensation and its working principle, the dynamic balance-compensation equipment based on combination of TSC and TSR are developed. With perfect compensation current waveform, TSC＋TCR compensation mode is suit for single-phase or three-phase traction transformer, in which load current can be compensated steplessly by compensation equipment, and both system reliability and safety are improved.
