Problems solved by technology
[0004] During the braking process of the current tram vehicles, a large amount of mechanical energy is consumed by the braking resistor, and only a small part is absorbed by the energy storage. Not only the energy utilization rate is low, but also a large amount of heat is discharged to the surrounding environment, which affects the ambient temperature.

Embodiment Construction
[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.
[0054] In this example, see figure 1 As shown, the present invention proposes a comprehensive optimization method for the whole interval operation of a catenary-free tram, comprising steps:
[0055] According to the comprehensive optimization of the operating parameters of the non-catenary tram, the running speed curve of the vehicle in this section is obtained, and the offline whole section is optimized;
[0056] When the actual speed of the vehicle deviates from the optimized reference speed under special circumstances, the vehicle adjusts the vehicle speed through the online speed regulation strategy and the optimal distribution strategy of electro-mechanical braking force.
[0057] As the optimization scheme of the above-mentioned embodiment, the offline full interva...

The invention discloses a comprehensive optimization method for full-range operation energy consumption of an overhead-contact-system-free tramcar. The comprehensive optimization method obtains the operating speed curve of the vehicle in the range according to comprehensive optimization of the operating parameters of the overhead-contact-system-free tramcar, and performs offline full-range optimization, and the vehicle measures and adjusts the vehicle speed according to on-line speed adjusting strategy and optimal distribution of electrical and mechanical braking power if the actual speed of the vehicle deviates from the optimized reference speed when the vehicle encounters a special situation. The comprehensive optimization method for full-range operation energy consumption of an overhead-contact-system-free tramcar obtains the operating speed curve of the vehicle in the range through comprehensive optimization, and the overhead-contact-system-free tramcar can arrive at the quasi-point and has the highest energy utilization efficiency when running according to the speed curve; and when the actual speed of the vehicle deviates from the optimized reference speed when the vehicle encounters a special situation, the vehicle adjusts the vehicle speed through the online speed adjusting algorithm and an electric and air brake optimal distribution algorithm to ensure that the vehiclearrives on time.
Description
technical field [0001] The invention belongs to the technical field of rail batteries, in particular to a method for comprehensively optimizing the operation of a catenary-free tram in all sections. Background technique [0002] Today, urban transportation has attracted more and more attention due to its pollution, noise and health characteristics. For example, buses in Europe account for about 50-60% of the total transportation, but 95% of them use gasoline as fuel. It has a very large impact on the environment. As a synonym for high efficiency, environmental protection, and energy saving, trams have been invested and constructed by more and more cities. They have the advantages of large transportation volume, fast speed, and safety. [0003] Due to the short distance between stations and many stations of rail vehicles, there are frequent starting and braking processes during the operation of the vehicles. Improving the energy utilization rate during the operation of the ve...
