Research On Energy-efficient Operation Strategy Of Urban Railway Vehicle

Urban rail transport for its superior performance in public transport plays an important role. In recent years, with the rapid development of urban construction, people’s expectations for urban transport are also increasing, thereby setting off a vigorous development of urban rail transport boom. In this context, this paper select the optimal operation of urban rail vehicle energy as the research object has important practical significance.In this paper, research on the following two aspects as follows:(1)Research on energy-efficient operation strategy of urban railway vehicle:This paper is based on the analysis of a series of such as the characteristics of urban rail vehicle traction, the factors influencing the process is running, running energy consumption, energy-efficient operation optimization mathematical description of the problem, energy-efficient operation of the substance, the size of the solution set of the different purpose of running strategy to research energy-efficient operation strategy of urban railway vehicle, designed urban rail transit traction calculation model of energy-efficient operation strategy. This paper Set energy-efficient operation strategy and research energy-efficient running operation parameters such as the electrical braking, maximum speed, uniform fluctuation amplitude, economic speed point, renew braking rate for energy-efficient operation strategy of urban rail vehicles. This is the core of this article.(2) Research on algorithm for energy-efficient operation of urban rail transit traction calculation. In this paper, running diagram algorithms, running energy consumption algorithms and optimal running searching algorithm for urban rail vehicles are corresponding improvements to improve the calculated effect.Through the research, the actual case of urban rail vehicle energy-efficient running traction calculate in this paper, this paper argues that the relatively better operation strategy of urban railway vehicle operation is the one that sequence for "maximum traction, uniform fluctuations, maximum braking".
