An artificial neural network (ANN)-based method for the design of virtual power meter, which is able to evaluate the power quantities for the single-phase system, is introduced in this paper. The solution procedure contains two stages. In the first stage, the spectral analysis of voltage and current signals are performed separately with the ANN-based method in the real-time manner. Then, the power quantities and evaluation indices are calculated in the second stage. Finally, a PC-based virtual instrument implemented with Lab VIEW is developed to verify the usefulness of proposed mechanism.
