The rotation frequency relay (RFR) is one of the most critical elements of automatic control system of the hydrogenerators. Accurate fixing of braking, subsynchronous and acceleration angular speeds contribute to operational reliability of many units of mechanical and electrical parts of the hydrogenerator and vise versa. Both experimental and theoretical investigations were performed on hydrogenerators. It was concluded that the rotation frequency relay, where an integrated voltage of the regulator generator is used as reference voltage and the elements of comparison are executed on the operating amplifiers, has a fairly high accuracy and stability of settings, and practically does not require regulation for manufacture and operation.
