Abstract

The modular multilevel converter (MMC) is one of the most attractive converter topologies for high or medium voltage power system. In this paper, a back-to-back modular multilevel converter is proposed for Scott railway traction system. The MMC works as a Railway Power Conditioner (RPC) which realizes active power flow control that balances the Scott Transformer's feeder currents, and achieves compensation of load harmonic currents as well. The circuit configuration and corresponding control strategy is discussed. A back-to-back MMC simulation model is built in the PSCAD/EMTDC software environment. The effectiveness of the RPC system is verified by simulation results.
