The authors suggest the concepts of protection relay systems for operation within a Smart Grid and describe the results of a prototype development. This paper introduces each of the system characteristics that should be considered for protection operation within Smart Grid, and the evaluation methods that were applied under both normal and faulted conditions. The results of a field trial in the 66kV...
This paper utilizes a significantly improved phase domain synchronous machine model [3] to test a multi-function relay model created for a real time digital simulator. One of the features of the machine model is its capability of simulating stator internal faults. Third harmonic voltage on the neutral and terminals of the machine and its variation with load and stator-ground faults is accurately represented...
Protective systems are essential for the safe operation of electrical power systems. The correct operation of a protection relay needs to be verified during its lifecycle, through production, to on-site commissioning and periodic maintenance. This paper presents an application designed to simulate the substation and power system protection of CEMIG GT in Brazil by means of a virtual reality environment...
