This paper summarizes implementation of an Adaptive Voting Scheme (AVS), which uses Wide Area Measurements (WAMs) from Phasor Measurement Units (PMUs) to make a classification of the operating state of the power system using decision trees to prevent critical transmission line misoperations. Using commercially available products on the market, this scheme was proved effective and efficient for implementation in a power system setting. Laboratory testing involved functionality testing of a Phasor Data Concentrator (PDC) for both PMU collection as well as a user-defined decision tree function. A hardware- and software-based PDC solution were determined to be effective means of determining the operating state of the system. Different relaying configurations including a Master-Slave and Programmable Automation Controller (PAC) set were tested and proved efficient for performing voting logic and breaker tripping.
