Practical Application of the Railway Static Power Conditioner (RPC) for Conventional Railways

摘要

Meidensha Corporation has been supplying the Railway static Power Conditioner (RPC) and Single phase Feeding power Conditioner (SFC) for Shinkansen lines as a measure for voltage fluctuations, imbalance of three phases, and for the effective use of transformer capacity at the power receiving point. Recently, we supplied the RPC to Aomori-nishi Substation as our first application of RPC to a conventional railroad line in Japan. Considering that Aomori-nishi Substation is designed to feed electric power for the station and load the rail yard where impedance of the load fluctuates from one of the respective windings and that the back power for the receiving circuit is small compared with that of the Shinkansen line, thorough demonstrative tests were conducted to verify the effect on the power supply system as compensation before the start of actual operations.
