Abstract: Due to the application of the electronic devices in power system, especially the application of the high voltage DC transmission technology in power system, the harmonic analysis theory and method for power system became very important. Based on the comparison of relevant methods, the principle of the modulation theory and its application in harmonic analysis and calculation were expounded emphatically. The advantages and disadvantages of the modulation theory were summarized; and at last, its development direction was prospected.
