Abstract :
This paper deals with design and implementation issues of a DSP-based single-phase shunt active power filter under distorted voltage source. A modified control strategy based on instantaneous reactive power theory (p-q theory) is proposed in this paper. Theoretical formulations for both original and modified p-q theories are presented. Simulations of the system in MATLABSimulink environment are conducted to validate the effectiveness and capabilities of the proposed control strategy. The designed shunt active filter with its current controller has been tested under a highly distorted voltage at the PCC with a 1-kV/40-V experimental prototype based on DSP TMS320LF2407A. Hardware results verify the feasibility and effectiveness of designed active filter and its capability in meeting the IEEE 519-1992 recommended harmonic standard limits.
