Abstract

In terms of electric energy measurement principle, combined with relative mathematic theory, this paper analyzes the harmonic power´s impact on linear and harmonic source load and unreasonable mode now. Based on this, using DSP technique, combing with the discrete Fourier transform, we set up a new calculation algorithm of electric power measurement fairly and with no fault to harmonic source load, and prove its reasonability and validity in practice.
