Abstract

The invention belongs to the technical field of urban mass transit and particularly relates to an energy-saving method of train operation of the urban mass transit. The energy-saving method comprises the steps of 1, analyzing operation matching rules of adjacent trains and computing the size of utilized regeneration energy; 2, establishing an optimization model of the train operation by taking the utilized regeneration energy as the target; 3, solving the optimization model to obtain an energy-saving time table of the train operation of the urban mass transit. By means of the energy-saving method, energy consumption during train operation is reduced, and security of an overhead line system is improved. Furthermore, the energy-saving method has the advantages of (1) being high in operation speed and applicable to large-scale computer simulation by adopting an integer programming method; (2) considering comprehensive factors, being high in modeling accuracy and strong in applicability of the planned operation time table; (3) being capable of embedded into hardware of a train energy-saving driving auxiliary system in an online mode, easy to implement, low in cost and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, and in particular relates to an energy-saving method for running an urban rail transit train. Background technique [0002] With the rapid development of urban rail transportation, Beijing, Shanghai, Guangzhou and other cities in my country have opened rail transit lines, with an operating mileage of 1,970 kilometers. During the "Twelfth Five-Year Plan" period, there will be more than 1,800 kilometers of new rail transit lines in 19 cities in my country, with a total investment of more than one trillion yuan. As the main line of urban public transportation and the main artery of passenger flow, urban rail transit is the fundamental solution to urban traffic congestion. However, the energy consumption of urban rail transit is also very huge. Taking Beijing as an example, the total annual traction electricity consumption exceeds 300 million kWh. Therefore, under the background of the ...
