A Two-Stage Solution Procedure for Digital Power Metering According to IEEE Standard 1459-2010 in Single-Phase System

摘要

This paper describes an artificial neural network (ANN)-based method for the design of a digital power meter, which is able to evaluate the power quantities suggested in IEEE Standard 1459-2010 for a single-phase system. The solution procedure contains two stages. In the first stage, the spectral analysis of voltage and current signals is performed separately with the ANN-based method in a real-time manner. Then, the power quantities and evaluation indices are calculated in the second stage according to the requirements in IEEE Standard 1459-2010. Finally, a personal-computer-based instrument implemented with LabVIEW is developed to verify the usefulness of the proposed mechanism.
