FPGA-based real time current sensor failure diagnosis for shunt active power filters

Abstract : The performances of conventional shunt active power filters heavily depend on accurate active filter current sensing. A sudden failure in one of the active filter current sensors decreases the filter performances. Moreover, if the fault is not detected and compensated for quickly, its effect leads to disconnection or hard failure of the active filter. Hence, to reduce the failure rate and to prevent unscheduled shutdown, a real-time fault detection, isolation and compensation scheme could be adopted. This article introduces a new fast and robust current sensor fault detection and compensation method for three-phase shunt active power filters. The proposed current sensor fault detection is achieved with a predictive model associated with a logical decision. The satisfactory performances obtained by experimental ‘FPGA in the loop’ prototyping validate the effectiveness of the proposed method.
