Abstract  Harmonic is one of the most important indicators for evaluating power quality. With the rapid development of power electronics technology, more and more non-linear equipment are put into operation, which affects the safe and stable operation of the power system seriously. Therefore it is extremely important to monitor and evaluate the intensity of harmonic interference. This paper first introduces harmonic monitoring, then makes some harmonic evaluation. At last, based on the calculation of harmonic power flow, this paper concludes the problems of multiple harmonic sources in the power grid.
