Abstract

The invention relates to a train run scheduling method in the field of urban railway transport, in particular to a design method for a railway transport drawing power balanced run chart based on particle swarm algorithm. The method includes main steps of firstly, acquiring data, and inputting railway line data, train run data and scheduling operational data which can be used for realizing analysis and calculation of the drawing power balanced run chart; secondly, initializing particle swarm by the aid of the data; thirdly, realizing ultimate of the particle swarm by the aid of the data; and fourthly, drawing the run chart. The drawing power balanced run chart is drawn according to optimal solution power balanced scheduling operational data. The design method is applied to an urban railway transport train operational scheduling system, peak power of a drawing transformer substation, drawing power consumption of trains and line loss on a drawing power supply system can be evidently reduced, power supply surplus capacity of the drawing power supply system can be increased, service lives of power transmission and distribution lines of the power supply system and equipment are prolonged, and safety of drawing power supply lines and the equipment are improved.

Description

technical field [0001] The invention relates to a train operation scheduling method in the field of urban rail transit, in particular to a method for designing a rail transit traction power balance operation diagram based on a particle swarm algorithm. Background technique [0002] In the operation process of urban rail transit, the power consumption provided by traction substation is the main consumption. The energy consumption of general subway lines is tens or even hundreds of megawatts, of which nearly 50% comes from train traction energy consumption. A large amount of traction energy consumption not only causes a high peak power impact on the traction substation, but also brings a heavy burden to the urban power supply system. The higher peak power of the traction substation will bring the following problems: First, the high peak power takes up a large capacity of the traction substation, and the electric energy capacity of the traction substation becomes smaller, which...

A large amount of traction energy consumption not only causes a high peak power impact on the traction substation, but also brings a heavy burden to the urban power supply system

The higher peak power of the traction substation will bring the following problems: First, the high peak power takes up a large capacity of the traction substation, and the electric energy capacity of the traction substation becomes smaller, which will cause serious damage to the increasing number of vehicles on the operating line. Second, the line loss on the traction power supply system increases significantly; the total energy consumption of the entire traction power supply system increases; third, the lines and equipment on the traction power supply system are prone to aging due to the impact of high peak power, and their safety Significantly lower sex

Although it can effectively utilize energy, it fails to solve the problem of the peak power impact of the traction substation on the safety of the entire traction power supply system and the problem of line expansion.
