Fast Turbine Valving

Abstract

The fact that, as a matter of necessity, power system steam turbines are in all cases equipped with control systems which include provision to close steam inlet valves rapidly on sudden loss of load as a way to suitably limit speed increase, implies that these systems are basically not difficult to modify so as to allow employment of fast valving as a way to maintain system stability despite the occurrence of a line fault or some other system stability endangering event.
