    Rotor Angle Stability

    A fault on the system causes rotor angle swings between connected generators, which is dependent on power mismatch, inertia and the time of fault clearance. In such cases the relative rotor angle differences between these sets are analysed or calculated using softwares. Associated with the...

    Load Shedding Scheme

    Under frequency relays, suggested by "gordonl" have found to be less effective, as it has first to wait for frequency to fall to its setting level and then has its own time delay plus intentional delay to allow the relay to ride through a power swings. The end result is it allows the...
