Review and prospect of the development of harmonic energy metering technology

mainly introduces the development and application of harmonic power metering technology in China since the 21st century. With the increasing demand for harmonic power metering in the power grid, the introduction of the world’s first harmonic power definition standard, IEEE 1459- - -2000, has promoted the development of harmonic power metering technology. The text also mentions the elements of the application and development of harmonic energy metering technology, including the expansion of the scope of harmonic pollution in the power grid, the confusion of harmonic energy metering instrument adopted by different users, and the new type of harmonic energy metering technology introduced in the world. In addition, this paper also introduces the domestic independent development of harmonic energy measurement technology,  such  as  0.2S  level  three-phase  electricity  meter,  0.2S  three-phase  harmonic  active  energy  metering  series products, three phase wave active energy metering products, and using the Hilbert digital filter and low frequency filter calculation harmonic reactive power metering chip development of cutting-edge practical technology. In general, this paper summarizes the development process, application status and future development direction of harmonic power measurement technology in China, as well as the related technology and product achievements.
