Abstract

The invention discloses an economical power matching and distributing method for an electric train. The method comprises the steps of S1, obtaining train information, line information and a target running curve of a to-be-calculated area; S2, according to the train information, the line information and the target running curve, calculating a demand power percentage curve when the train runs basedon the target running curve; S3, forming a minimum power unit number and train running position curve according to the total number of minimum power units of the train and the demand power percentagecurve, and distributing the working states of all the power units according to the minimum power unit number and train running position curve to obtain instruction sequences for inputting or removingthe power units; S4, calculating the power units, put into work at all positions of the target running curve, among the power units, and calculating an actual level instruction sequence of each powerunit; S5, outputting the instruction sequences for inputting or removing the power units and the actual level instruction 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...
