Power quality assessment in V-V, Clarke and Park domain

This paper presents a computer aided novel technique for electric power quality assessment. This has been done by assessment of unbalance and presence of harmonics in a power system. This is achieved by developing some feature patterns formed by power system data, wherefrom rule set has been generated to analyze unbalance and presence of harmonics in a power system. The study of the unbalance is accomplished in voltage-voltage plane, whereas the study on harmonics is done in Clarke and Park domain using Clarke and Park transformation matrices.
