Abstract
Aiming at the problem of limited power battery capacity of pure electric Load-Haul-Dump (LHD), a method of charging and supplying sufficient power through pantograph-catenary current collection system is proposed, which avoids the problem of poor flexibility and mobility of towed cable electric LHD. In this paper, we introduce the research and application status of pantograph and catenary, describe the latest methods and techniques for studying the dynamics of pantograph-catenary system, elaborate and analyze various methods and technologies, and outline the important indicators for analyzing and evaluating the stability of current collection between pantograph-catenary system. Simultaneously, various control strategies for pantograph-catenary system are introduced. Finally, the application of the pantograph-catenary system in high-speed railway and urban electric bus is discussed to illustrate the advantages of pantograph-catenary system charging and energy supply, and it is applied to pure electric LHD charging and energy supply to ensure power adequacy.
