R450 Automatic Voltage Regulator AVR of Three-Phase Alternators/Diesel Generator Sets AVR

R450 AVR is powered by two auxiliary windings which are independent of the voltage equal circuit. The power supply voltage is rectified and filtered before being used by the AVR monitoring transistor. With PMG excitation, a permanent magnet generator (PMG) added to the alternator supplies the AVR with voltage.

On Application of load, the rotation speed of the generator set decreases, when it passes below the preset frequency threshold the LAM causes the voltage to drop by approximately13% or 25%, and consequently, the quantity of active load applied is reduced by approximately 25% to 45% until the speed reaches its rated value again. Hence the LAM can be used either to reduce the speed variation (frequency) and its duration for a given applied load or to increase the applied load probable for one-peed variation (turbocharged engine).
