“…The proposed stability analysis has proved useful in the systemic design of controllers for AC voltage control for electronic frequency converters [1] with a constant power-factor output installed at the Numazu frequency conversion substation, for power compensators that balance electric power on the feeding side (RPC: Railway static Power Conditioner) installed at the Ritto power substation, and for other power compensation equipment. This equipment has been operating smoothly since February 2009.…”

The recent introduction of very fast and frequent train service on the Tokaido Shinkansen makes it difficult to stabilize the feeding voltage solely by compensating reactive power. Therefore, active power compensation has been introduced for further stabilization of the voltage, and a converter control strategy called the “fixed power factor method” was applied in commercial operation that started in February 2009. Feeding voltage stabilizing control by active power compensation is substantially more complicated than conventional reactive power compensation. This paper describes a novel stability judging method for the Shinkansen feeding system with multiple power converters; this method can be used to determine appropriate active/reactive compensation strategies that can be used by the operator of the new Shinkansen power supply system. © 2012 Wiley Periodicals, Inc.

“…Therefore, rotary frequency changers (RFCs) were installed to make 60 Hz AC for traction power supply system. Recently, a static frequency converter, which is called EFC (electronic frequency converter), has become feasible, and EFCs have been partially installed at four FCs (frequency conversion substations), namely at Oi FC, Tsunashima FC, Nishisagami FC, and Numazu FC for energy saving and less maintenance. Table shows specifications of EFC at Oi FC .…”
