摘要
在平衡变压器负序补偿特性基础上,提出利用无源对称补偿原理来构成同相供电方案.针对不同性质的牵引负荷,借助负序向量图分析方法,直观地分析了不同方案中各端口补偿容量配置,得出以αβ端口对外供电所需要的补偿容量最小的结论.最后以交直交型机车负荷为例进行了仿真,仿真结果验证了理论的正确性.
Some schemes of cophase power supply used to passive symmetric compensation was presented which combined balance transformer negative sequence compensation characteristic. In view of different traction loads, applying negative sequence diagram analysis compensation capacity derived derectly in all port and concluded the αβ port is the best power supply port which need the leaset compensation capacity. In the end, the simulation result on AC-DC-AC electrical locomoter load shows the correctness and validity of the proposed theory.
