Research On Optimized Control Energy-Saving Scheme Of Freight Train

With a mass population,demand of energy is also increasing. Therefore, in the current development and utilization of new energy sources and improving energy efficiency can not be achieved under the breakthrough in the short term, the energy-Saving is particularly important. In all of the current national economic departments, the railway transport sector is one of the largest energy-consuming sectors. According to incomplete statistics, in the whole rail transport energy consumption, the energy consumed by the locomotive can account for about 65%-75% of the total rail transport energy consumption,and among its high load,transport distance, running lines and complex characteristics of the entire locomotive energy consumption also account for a large proportion. Therefore, the problem of energy-Saving freight train development for our country have a very deep meaning.In this paper, a unified model for freight trains DF4 B type, and the train in research in a variety of operating conditions during the force, combined with the relevant traction calculation and energy calculation methods, the use of intelligent heuristic algorithm to calculate the energy-Saving freight trains operated control strategy and its optimization. The main contents are as follows: The first section summarizes the current research in the manipulation of energy-Saving aspects of the train, and raise questions about with the shortcomings of the existing research in terms of freight trains save energy manipulation,leading to the main content of this paper on the basis of : The freight train operation control to optimize energy efficiency and concluded; The second part introduces some definitions and theories related to genetic algorithms, and analyzes the feasibility of using genetic algorithms to solve the freight train saving energy manipulation problem, provide theoretical support for the following; The third part by studying factors affecting freight train during operation and traction calculation of energy consumption and energy consumption calculation method stress situation, given the process of freight train running; The fourth part is the core content of this article, based on a freight train running process factors affecting energy consumption and energy-Saving trains operated on the principle of optimization analysis, by determining the the locomotive throttle position, the parking brake calculations to determine the ramp balancing speed determine the adjustment ramp, adjust the ramp control to determine the set of energy-saving steps such as the establishment of a freight train operation control strategy and optimization models; The fifth part is also an important part of this paper, the part by designing an adaptive genetic algorithm to build a model of the fourth part optimization, and through an example proves the validity of the model.In the course of this paper, the use of VC ++ and MATLAB software for the fifth part of the calculation examples given freight train optimal energy-Saving strategies to manipulate within a specific range, and the results were compared with the original, this algorithm the feasibility of proof.
