Document Type and Number:
WIPO Patent Application WO/2024/092907
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a power control method and apparatus. The method comprises: acquiring the real-time speed and the operation resistance of a train at a first moment; according to the real-time speed and the operation resistance, determining required output power required by the train to maintain the real-time speed; on the basis of the required output power and the maximum output power of the train at the first moment, determining the number of power units of the train that can be turned off, wherein the power units may be power axles, bogies, or power cars; and controlling operation of the train according to the number of the power units that can be turned off. Due to the fact that the number of the power units that can be turned off is determined according to the real-time working condition of the train, the number of the power units that can be turned off is based on the real-time working condition, and after corresponding power units are turned off according to the number of the power units that can be turned off, the remaining power units can exert higher efficiency, so that by means of intelligent distribution of the power of a traction transmission system, the efficiency of a train power system is maximized, thereby achieving the effect of reducing energy consumption.
