C-code Implementation of a Shunt Active Power Filter Based on Finite Set Model Predictive Control

This paper proposes the design of an instantaneous power theory based 3-phase 2-level Shunt Active Power Filter (SAPF) for compensating current harmonics and reactive power using C-codes. The application of Finite Set Model Predictive Control (FS-MPC) for generating the compensating currents is also investigated in this paper. Additionally, the design of a High Pass Filter to extract oscillating component of active power and a controller to balance the dc link voltage is presented. The entire active power filter has been designed using C-codes which allows it to be directly implemented in a real time system. Furthermore, a MATLAB/SIMULINK model has been designed to inspect the operation of the developed active filter.
