The invention discloses an adjusting method and system suitable for a traction power supply network, the adjusting system is applied to a train traction converter system, the adjusting system obtains the current network voltage of a traction network in real time through a network voltage monitoring module, and whether a high-frequency resonance phenomenon occurs currently is judged through a central control module according to the current network voltage of the traction network; and under the condition that the high-frequency resonance phenomenon exists at present, a control signal is sent to each rectification module and/or transmission control module to eliminate the high-frequency resonance phenomenon. According to the adjusting system, high-frequency resonance can be avoided, or control is carried out in time when high-frequency resonance occurs, accident expansion is avoided, and the adaptability of the train running in different power supply intervals is enhanced.
本申请公开了一种适应牵引供电网的调节方法及系统,该调节系统应用于列车牵引变流系统,该调节系统通过网压监测模块实时获取牵引网当前网压,通过中央控制模块根据所述牵引网当前网压判断当前是否出现高频谐振现象,在当前存在高频谐振现象情况下,向各个所述整流模块和/或传动控制模块发送控制信号以消除高频谐振现象。该调节系统能够避免发生高频谐振、或者已经发生了高频谐振但及时进行控制,避免事故扩大,增强列车在不同供电区间运行的适应性。
