"Stiff Grid" and Parallel Operation AC Generator Excitation Regulator
SVRFP - Kinetics Industries
The Kinetics model SVRFP Exciter/Regulator rectifier is designed and rated in capacity and operating parameters for the application of exciting the fields on an AC generator in parallel with other AC generators and the power system is a "stiff system" in relation to loading. A "stiff system" is a generating system that is of sufficient capacity or the generator is "small" in relation to the system grid, that the AC system voltage under impulse/step loading condition does not require forcing of the generator field to maintain the power grid voltage. Systems are designed with a standard unit service factor to operate within the +10% to -20% nominal voltage rating at 100% current rating.
