| Abstract: | The paper presents the results of investigations into several methods of calculating the active power value from current and
voltage signal samples. The accuracy attainable for nonsinusoidal signals whose frequency differs from the nominal one was
determined. A new active power calculation method ensuring accurate results for sampling over two signal periods is proposed.
The method uses a very simple computing algorithm. |
