One of the most common solutions to deal with the power quality issues of electrical railway systems is employing Railway Power Conditioner (RPC). In the conventional mode of operation, the RPC power rating deployed in every Traction Power Substation (TPS) is significantly large. This paper mainly focuses on the power rating reduction of RPC through presenting a novel combinatorial compensation method. The inductive and capacitive switching algorithm retrieved from Steinmetz circuit lead to additional auxiliary balance in sequential TPS which declines the RPC function in elimination of the Negative Sequence Current (NSC). The proposed method can reduce the voltage over Sectioning Posts (SP), DC-link operation voltage, back-to-back (B2B) converters rating and installation costs. The accuracy and effectiveness of the proposed strategy are confirmed via simulation results obtained by MATLAB/SIMULINK program.
