Abstract：To improve power quality and overcome excessive neutral sections in traditional two-phase traction supply system, single-phase traction supply system adopting railway static power conditioner (RPC) is a feasible solution. However, relatively high power capacity limits its large scale industrial application. To enhance the cost-efficiency and reliability of the compensation system, a LC-coupled RPC (LC-RPC) is proposed in this paper. Based on the operating properties of LC-RPC, a minimum operating voltage design for LC-coupling branch is proposed, which is suitable for the fluctuating railway load. And then, a detailed capacity comparison between LC-RPC and RPC is discussed as well. The results indicate that the LC-RPC is better to decrease capability than RPC. Finally, based on the measured data of a traction substation, the effectiveness of LC-RPC and its ability of capacity decreasing have been verified.
