Keywords: high-speed railway, pantograph-catenary system, 400 km/h and above, current collection quality, parameter optimisation, numerical modelling.

In this survey paper, we comprehensively examine the ongoing research concerning the interaction between pantographs and catenaries, a vital aspect in ensuring uninterrupted electricity supply to trains. Future perspectives for future studies to ensure satisfactory performance at 400 km/h and above are preliminarily explored. Initially, this paper provides an overview of the current design and assessment system. A systematic survey on the numerical modelling of pantograph-catenary interaction is conducted. The applicability of current assessment quantities to speeds of 400 km/h and above is preliminarily investigated with a numerical model. The potential of optimising parameters for improving interaction performance is also explored at this speed level. The paper further reviews and preliminarily analyses the effects of common disturbances, such as geometric deviation on the pantograph-catenary interaction performance at 400 km/h and above. Overall, this paper offers insights into the current state of research on pantograph-catenary interaction for high-speed railways and proposes future directions for improving the system to ensure optimal performance at speeds of 400 km/h and above.
