WebThe AVR input voltage is given to the excitation generator, Typically the value between 5 Amps to 50 amps depending upon the alternator capacity. For 24 MW alternator, the AVR output voltage is 65 V VDC, 6.95 Amps. But in the excitation transformer produces around 240 VAC, 280 Amps the same Input voltage with full load condition. http://genspare.com/upfile/202403/2024030860135633.pdf
WebThe voltage from PMG passes to the AVR and then moves to the exciter coil. Here, the amount of voltage is either fixed or it depends on the speed of rotation of the generator. While the self-excited generator generates its own electricity with the exciter coil to send to the rotor, PMG-excited generators use PMG to produce voltage supply.
WebOct 15, 2016 · The generator control system has been modified a lot over the years, and is now used a modern PLC for sequencing, a SPM-A for synchronising, and a 2301D for governing. The SPM-A doesn't voltage match and there is no sync-check relay, which is part of the problem.
