Sažetak

Despite its many advantages, the conventional direct power control (DPC) of shunt active power filters (SAPF) poses some problems. This paper investigates the design of a new control technical combining DPC control and passivity theory (PT) to ensure quasi-sinusoidal grid currents, under various conditions of the source voltages. The proposed approach (DPC-PT) appeals to the theory of symmetrical components (negative and positive) to solve the problem of disturbed voltages signals during a grid imbalance. The implantation of the DPC-PT methodology was developed under Matlab/Simulink environment. Simulation results showing the operation and performances of the SAPF in steady and transient states have been presented. The found results show the satisfactory dynamic response and the improvement of network behavior in the presence of an imbalance.
