Harmonics have emerged as a prominent power quality concern in power systems. Accurate estimation of harmonic parameters in the power grid is not only a fundamental requirement for effective harmonic management but also a crucial foundation for power enterprises and users to assess the extent of harmonic impact. Therefore, a harmonic analysis method for power systems based on double frequency-shift filtering is proposed in this paper. The method initially applies frequency-shift filtering to the original grid signal, obtaining the fundamental frequency deviation and forming anew frequency-shift factor. Subsequently, employing the determined fundamental frequency and the updated frequency-shift factor, a secondary frequency-shift filtering is applied to the original grid signal. Finally, the amplitudes and phases of individual harmonics are computed through deduced formulas, utilizing the power grid signal acquired after the secondary frequency-shift filtering. Simulation experiments show the algorithm's attributes, including notable measurement accuracy, exceptional real-time performance, and robust adaptability. Furthermore, validation of the algorithm's accuracy and effectiveness is accomplished by testing it on an actual hardware platform.
