Power distribution optimized scheduling method of motor train neighborhood sub-system

Abstract

The invention provides a power distribution optimized scheduling method of a motor train neighborhood sub-system, and the method comprises the following steps that (1) a single compartment of a motor train unit serves as a local sub-system, and local sub-system models of the motor train unit are respectively built according to different stress on the head compartment, a tail compartment and compartments between the head and the tail of the motor train unit; (2) a motor train neighborhood sub-system model is built according to the local sub-system model of the motor train unit; (3) constraint conditions during the operation process of the motor train unit are established according to the resultant force on each compartment; (4) an optimized and controlled target function is determined according to the mutual acting force among the compartments in the motor train neighborhood sub-system model, a prediction time domain and a control time domain; and (5) the target function is solved under the constraint conditions to obtain the optimized scheduling of power distribution during the operation process of the motor train unit. According to the power distribution optimized scheduling method of the motor train neighborhood sub-system, the power distribution prediction control of the high-speed motor train unit can be realized, so that the control freedom of each compartment is higher, the response is quicker, and the power distribution efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a distributed optimization control method for an EMU, in particular to a power distributed optimal dispatching method for an EMU neighborhood subsystem. Background technique [0002] In recent years, China's economic strength and comprehensive national strength have been significantly enhanced, and China's railway system has also undergone substantial upgrades and expansions. On April 18, 2007, my country's railways carried out the sixth major speed increase. In this speed increase, my country launched the CRH series high-speed EMUs CRH1, CRH2 and CRH5 for the first time. The operating speed of these EMUs reaches 250km / h. According to the medium and long-term development plan of my country's railways, by 2020, the scale of China's railway network will reach more than 120,000 kilometers, and 16,000 kilometers of "four vertical and five horizontal" high-speed railway networks will be built. In the future, ...
