摘要
A comparative analysis of methods of measuring reactive power for ac networks is carried out. Analytic relations for the systematic error as a function of the current and voltage parameters are obtained. For the method based on a Hilbert converter, the complexities of its practical realization are considered. It is shown that for ac networks, the method based on the discrete Fourier transform of the current and voltage is the most accurate.
