摘要：
To evaluate the loading capacity of the power supply system of dual- source trolleybuses in the planning and operation of public transit system, this paper analyzes the constraints that affect the power capability of the two power supply systems from the two aspects: the catenary power supply and the on-board energy storage power supply. Power capacity calculation models of the power supply system with typical topologies are established. Meanwhile, the power demand model of dual- source trolleybuses considering multi- vehicle driving conditions is established based on the statistic data and least- squares parameter identification. The calculation method of loading capacity for catenary power system which takes the acceptable number of vehicles as an index is proposed. The calculation model for the loading capacity of the on-board energy storage power supply system is established, and its related calculation method with the off-line ratio as the core index is proposed as well. Finally, the case studies are performed based on the operation data of dual-source trolleybuses in Beijing. The comparison between the calculation and the simulation results verifies the accuracy of the model. The calculation method can provide references to the operation and planning of dual-source trolleybuses. Copyright © 2018 by Science Press.
