Harmonic interference is a major hazard in the current power system that affects quality. How to extract harmonics quickly and accurately premise ensure sustainable operation of system, which particularly important field new energy generation. In this paper, harmonic extraction method based on time-varying observer proposed. Firstly, frequency estimation algorithm used estimate grid frequency, ...
