Abstract :
The purpose of the equipment described is to separate the power system when an out-of-step between two groups of generators within it is predicted. The out-of-step prediction method is based on the generator´s angular-velocity data measured by electromagnetic sensors and gears that are fastened directly to the rotors. The equipment was tested by the large-scale power system simulator APSA (Advanced Power System Analyzer) and was also field tested. The results are presented.<>
