The invention discloses a train power supply system power control method and system and a power centralized electric vehicle set, which calculate the temperature difference between the water inlet temperature and the water outlet temperature of a train power supply cabinet, and adjust the power of a train power supply system according to the difference between the temperature difference and a standard temperature. According to the method for adjusting the train power supply output power based on the water inlet and outlet temperature difference, intelligent adjustment of the train power supplycabinet output power can be achieved, and the problem that the temperature rise is too high due to train power supply cabinet overload when a trailer has an overload working condition or a power train set power supply cabinet single-module fault is solved.

    本发明公开了一种列车供电系统功率控制方法、系统及动力集中电动车组,计算列车供电柜进水口温度与出水口温温度的温差,根据该温差与标准温度之间的差值大小,调节列车供电系统功率。本发明基于进出水口温差调节列车供电输出功率的方法可实现列车供电柜输出功率的智能调节,解决了拖车出现过载工况或动力车列供柜单模块故障时,列车供电柜过载导致温升过高的问题。
