要約(英語): Since the 1960's, rotary frequency changers (RFCs) have been used as frequency converters applied to AC power supplies of high-speed railways, and they still play a major role today. On the other hand, electronic frequency converters (EFCs), which have advantages compared to RFCs in terms of maintenance cost and energy saving, have been introduced, and we have been working toward increasing the installation ratio of EFCs. As a result of the progress, we have reached a stage where we need to reduce the number of frequency conversion substations (FC-SSs) that require RFCs in order to further increase the installation ratio of EFCs. Under this situation, we studied a new interconnection control technology to realize the interconnection operation with the existing remote power supply systems to replace all RFCs with EFCs at the Nishisagami FC-SS of the Tokaido Shinkansen. In this paper, we present a new control block diagram for the fixed power factor output method voltage control with reference voltage command value adjustment for EFCs, which can prevent overload of a power supply system placed apart while maintaining stable voltage when EFCs are interconnected to distant power supplies.
