A Wide-Area Measurement Concept with Low-Cost Terminal Acquisition Units for Power System Quality Analysis

With the development of smart grids, power-quality monitoring becomes the one of the necessary functions. However, the installation of numerous terminal units usually would increase the cost for the wide-area measurement. In order to promote the deployment of distributed measurement, the low cost acquisition units are applied in this paper. By combining the proposed reconstruction technique for power signals, the embryo of wide-area power-quality measurement network is built.
