| Abstract: | The article describes the application of Lab Windows/CVI in electric energy quality measurement. It then discusses the influence of electric energy on power system and the computational method of harmonic parameters, which includes evaluating amplitude value and phase of lowest frequency and harmonic by fast Fourier transform, and calculating signal phase difference by method of correlation. It also presents the systems design of virtual electric energy analysis instrument, including the design of electric circuits for hardware and software. |
