Abstract
In the Tokaido Shinkansen, rolling stock types have been unified with an inverter controlled type, which was introduced after Series 300. As a result, the input power factor of the main converter of the rolling stock has been controlled to 1. In accordance with this change, the role of reactive compensation of SVC has shifted from the load power of trains to the power consumed by the reactance in an electrical power system. Therefore, considering the aging of power converters, it is time to reassess their layout and the configuration for the future of the Tokaido Shinkansen. We reassessed the equipment configuration, capacity, and layout of power converters as well as verified the impact on the stabilization of power supply when introducing self-commutated power converters.
