A Flexible GPS-Based System for Synchronized Phasor Measurement in Electric Distribution Networks

Large-scale distributed measurement systems are the object of several applications and research. The goal of this paper is to develop, by employing Global Positioning System (GPS) receivers, measurement techniques that are suited to the continuous monitoring of the electrical quantities in distribution networks in terms of synchronized phasors. The proposed measurement procedures, differently from commercially available phasor measurement units, are based on general-purpose acquisition hardware and processing software, thus guaranteeing the possibility of being easily reconfigured and reprogrammed according to the specific requirements of different possible fields of application and to their future developments
