Abstract
In this paper a concept of instantaneous imaginary power (IRP) theory has been proposed for the load compensation of three phase balanced system. In this theory the total power is separated into two components, namely imaginary and real instantaneous power. The instantaneous imaginary power has been considered as zero and dc component of the real power is therefore selected as compensation power reference for compensation of harmonics and reactive power. In the design of active power filter (APF) three current, two ac voltage and one DC link voltage sensors have been used. By using this approach the overall system design becomes easier to accomplish and the implementation cost has been reduced. The model is prepared in MATLAB/SIMULINK and the system with the proposed theory has been tested for non-linear loads. The harmonic analysis of supply side quantities comply with the IEEE 519-1992 recommendations of harmonic standard limits, which validate the implementation of proposed shunt active power theory.
