The invention discloses a rail transit converter control method and system which are applied to a rail transit system, and the rail transit system comprises a plurality of traction substations; each traction substation comprises at least one converter; the method comprises the following steps: at least acquiring position information and running state information of a train through a communication network; the trains are all trains between the (n-1) th traction substation and the (n + 1) th traction substation; the (n-1) th traction substation and the (n + 1) th traction substation are traction substations closest to the left side and the right side of the nth traction substation; the nth traction substation is any traction substation; obtaining a slope influence value corresponding to the nth traction substation according to the position information and the running state information of the train; and adjusting the output characteristic curve of the corresponding converter according to the slope influence value. The output characteristic curve of the converter can be adjusted in real time according to the position information and the running state information of the train, coordinated control is achieved, and power distribution is optimized.

    本申请公开了一种轨道交通变流器控制方法及系统,应用于轨道交通系统,轨道交通系统包括:多个牵引变电所;每个牵引变电所包括至少一个变流器;方法包括:通过通信网络至少获取列车的位置信息和运行状态信息;列车为第n‑1牵引变电所与第n+1牵引变电所之间的所有列车;第n‑1牵引变电所和第n+1牵引变电所为第n牵引变电所左侧和右侧距离最近的牵引变电所;第n牵引变电所为任一牵引变电所;根据列车的位置信息和运行状态信息,获得第n牵引变电所对应的斜率影响值;根据斜率影响值,调整对应的变流器的输出特性曲线。本申请能够根据列车的位置信息和运行状态信息实时调整变流器的输出特性曲线,实现协调控制,优化功率分配。
