Abstract

The invention discloses a method for matching and distributing economical power of an electric train, including S1, obtaining train information, line information and target running curve in the area to be calculated; S2, calculating according to the train information, line information and target running curve And obtain the required power percentage curve when the train is running based on the target operation curve; S3, according to the minimum power unit total number of the train and the required power percentage curve, form the minimum power unit number and the train operating position curve, and according to the minimum power unit number According to the train running position curve, the working state of each power unit is allocated, and the command sequence of power unit input or removal is obtained; S4. Calculate the power unit that is put into work at each point of the target operation curve, and calculate and obtain the power unit of each power unit. Actual level command sequence; S5, outputting the command sequence of switching on or off the power unit, and the actual level command sequence of each power unit.

Description

technical field [0001] The invention belongs to the technical field of train operation control, and in particular relates to an economical power matching and distribution method for electric trains. Background technique [0002] my country's railways have gradually entered the period of operation and maintenance from a period of great development. How to effectively improve energy utilization has become one of the main goals of China Railway Corporation and various railway bureaus. Effective energy saving and emission reduction can not only reduce the operating cost of the railway system, but also effectively support the national environmental protection requirements, thereby effectively improving the economic benefits and social image of the enterprise. [0003] Traditional research mostly starts from the perspective of line operation and train energy-saving operation, such as studying train operation diagrams and optimizing timetables in order to reduce train delays and in...
