成果简介	NOVELTY - The frequency relay has a rectangular pulse generator (2), an information processing circuit, a key (9) and a responsive element. A half-wave rectifier is connected to the input of the operational amplifier (1). The output of peak detector (5) is connected through the first input of the comparison element (6) to the control input of the variable resistance in the amplifier feedback. A setting device is connected to the second input of the comparison element, and is made in the form of a potentiometer. A pulse generator (10) is connected to the output of the operational amplifier. The output of operational amplifier is connected to the first input of the key. A clock pulse generator is connected to the second input of the key. The output of the key is connected to the pulse counter of the microcontroller (11). USE - Frequency relay used to control frequency of voltage in network. ADVANTAGE - The accuracy of network frequency control is improved. The output of the key is connected to the pulse counter of the microcontroller, which ensures increased accuracy of network frequency control. The amplitude instability does not affect the conversion error. DESCRIPTION OF DRAWING(S) - The drawing shows a circuit diagram of a frequency relay. 1Operational amplifier 2Rectangular pulse generator 5Peak detector 6Comparison element 9Ket 10Pulse generator 11Microcontroller
