Single-phase STATCOM for feeding system of Tokaido Shinkansen

In the Tokaido Shinkansen, SVCs (static var compensators) have been installed at the single-phase feeder side in select substations to reduce the descent in the feeding voltage. A single-phase STATCOM (static synchronous compensator), called an RPC (railway static power conditioner), consists of a back-to-back converter whose AC terminals are connected to the two power systems of a Scott transformer. When the two terminals of the RPC are connected to a single power system, the RPC can operate as an SVC. RPCs can both control the feeder voltage and equalize the unbalanced power flow between the two single-phase power systems. In this paper, we present the simulator test and field test results of the RPCs installed in select substations of the Tokaido Shinkansen.
