Implementation of a Security-Dependability Adaptive Voting Scheme

Today¿s electric power system is operated under increasingly stressed conditions. As electrical demand increases, the existing grid is operated closer to its stable operating limits while maintaining high reliability of electric power delivery to its customers. Protective schemes are designed to account for pressures towards unstable operation, but there is always a tradeoff between security and dependability of this protection. Adaptive relaying schemes that can change or modify their operation based on prevailing system conditions are an example of a protective scheme increasing reliability of the power system. The purpose of this work is to validate and analyze implementation of a Security-Dependability Adaptive Voting Scheme that utilizes synchronized phasor measurements and decision trees.
