Feedforward Compensation of Railway Static Power Conditioners in a V/v Traction Power Supply System

Railway static power conditioners (RPC) usually improve the quality of traction supply systems only according to active load, which leads inaccurate compensation. There are two factors that restrict performance RPC, one is reactive and other system error. In order eliminate compensation error, a optimization method proposed. First, calculate value for load. Second, introduce amplitudes phases primary currents V/v transformer as references error caused by loss then use fuzzy control optimize The proposed in this paper actually feedforward control. addition, balances three-phase enables RPC be used railway with low locomotive factors. effectiveness has been confirmed simulation results.
