속도 향상을 위한 고속전철 TGV-K 집전시스템의 성능에 관한 연구

A Study on Performance of TGV-K Current Collection System for the Speed-up

Described in this paper are the dynamic model and the dynamic performance of catenary-pantograph system for TGV-K(maximum operating speed of 300km/hr). Dynamic simulations showed that the system satisfies the performance criteria such as contact loss ratio, contact force and lift-off of the contact wire. It is also shown by the simulations that the dynamic behavior and contact performance of the system at the operating speed of 350km/hr are found unacceptable. Design parameters of the catenary-pantograph system should be optimized for the speed-up of the TGV-K.
