The quantitative analysis of electric meter measurement error with harmonic sources

With the development of power electronic technology, it has become the main harmonic sources in the grid. This paper is based on the theory of induction meter and electronic energy meter. First the mathematical expressions of respective meter under harmonic are induced, and next the influence factor of the electric meter measuring error is analyzed. The theory of induction electric meter and electronic energy meter is respectively utilized for simulation analysis. Finally, combined with theoretical calculation and simulation analysis, the conclusion on the impact of harmonics on electric meter measurement is drawn.
