Abstract For power quality in high-speed electrified railway, this paper proposes a novel power quality comprehensive compensation system to compensate negative sequence current and harmonics. The system is made of railway static power conditioner(RPC), thyristor-controlled reactor and 3rd harmonic filter. In order to compensate the negative sequence current, passive devices can provide fixed-capacity capacitative and inductive current to change phase difference of two power traction currents. According to compensation principle, then RPC is used to transfer the active power, compensate the remaining reactive power and suppress harmonics, so the active capacity and cost are reduced. Taking account of AC characteristics of current signal, a recursive PI controller is adopted in this paper which can eliminate the steady-state error and improve the dynamic performance. A set of reasonable circuit parameters is calculated, and the simulation and experiment results prove that the proposed hybrid topology and control model are feasible and effective.

Key words： High-speed electric railway railway static power conditioner(RPC) negative sequence current compensation active power transfer control model fuzzy recursive control
