Pantograph Active Control Algorithm Development According to Contact Force Variation

초록

If the train operates at high speed in tunnel section, the pressure wave will happen. The uplift force of current collection system may vary abruptly and the quality of current collection will be deteriorated because of pressure wave. If the rigid trolley bar system is used in tunnel section, the contact loss will happen and it is difficult to improve the commercial speed. Therefore it is very important to interface pantograph and catenary system in order to improve the commercial speed-up in tunnel section. This paper deals with the an active pantograph control algorithm to decrease the contact force variation.
