Abstract
In recent studies, hierarchically distributed non-intrusive agent aided transmission line distance relaying protection scheme has been proposed. This scheme is meant to provide the distance relays with situational awareness and improve their robustness against hidden failures. Distance relaying protection scheme is a part of safety critical cyber physical system (in particular, power system) and it operates with stringent timing requirements to remove the faulted line out of service. Before putting into practice, it is better to formally verify that the agent based relay supervisory scheme meets the specifications and its usage gives intended results and doesn’t carry any negative side effects. Therefore, in this paper agent based relay supervision scheme is formally modelled, validated and its properties are verified using UPPAAL - a timed automata based formal verification tool.
