Hybrid simulation to test control strategies in active power filters using generalized power tensor theory

This paper presents a hybrid simulation to test control strategies in active power filters using the generalized power tensor theory. The tensor theory is based on the dyadic or tensor product between voltage and current vectors. This new definition allows the estimate of reference currents for the control of active power filters “APFs” in multiphase systems. The hybrid simulation consists in a combination of computer simulation and laboratory tests. This approach is a cost effective alternative to physically testing the whole system and allows study the dynamic behaviour of complex engineering systems. Besides, it describes implementing an active power filter (APF) hybrid prototype where the source system and load are implemented as a real-time simulation and the active power filter is implemented in physical hardware. It also confirmed the hybrid simulation results by implementing the simulation in MATLAB-Simulink regarding the same system implemented during the active power filter analysis and design stage.
