The invention relates to the technical field of locomotives, and discloses a method for improving track signal compatibility of an alternating current transmission locomotive, which is characterized in that an inverter of a traction converter is controlled in a mode of combining random switching frequency control and fixed switching frequency control in a locomotive running full-speed interval. According to the invention, the problem that the compatibility of AC transmission locomotive track signals is difficult to improve in the prior art is solved.

    本发明涉及机车技术领域,公开了一种提升交流传动机车轨道信号兼容性的方法,在机车运行全速度区间,对牵引变流器的逆变器的控制采用随机开关频率控制和固定开关频率控制结合的方式。本发明解决了现有技术存在的难以提升交流传动机车轨道信号兼容性等问题。
