摘要：

This paper introduces a new approach to the design of digital algorithms for electric power measurements. Digital algorithms for electric power measurements are represented as 2D digital FIR filters applied on voltage and current samples. Based on this approach, a new technique for algorithm design is developed. As the main advantage, the technique provides a convenient way to design new algorithms for measuring the electric power components according to various definitions in both sinusoidal and non-sinusoidal conditions. Several new algorithms are derived by using the proposed design technique. The existing algorithms for power measurements are also derived by using the new approach. The algorithm performance is tested using actual signal recordings.
