ABB UNITROL F Automatic dual channel voltage excitation regulator device AFT

ABB UNITROL F Automatic dual channel voltage excitation regulator device AFT

AVR:apply to grade and below 1000 MW generating units
SES:apply to grade and below 135 MW generating units

- optional standard channel(SFE)or automatic dual-channel configuration(AFT)

SFE for the single automatic channel (PID regulation) with a manual channel (PI regulation.AFT is dual-channal , each with a channel manually by independent UNITROL F excitation module and each module has all the AVR features with independent power bridge, the two track each other mutual hot standby. One online channel, another channel rectifier bridge control pulse is blocked.Switching logic: A fault automatically access channel B(automatic), B-channal(automatic) re-fault, if the A-channel(automatic) fault recovery switch to the A-channel, or switch to B-channal(manual., Exciting with flu-loop system, B channel manually to a sense of failure was cut to transfer. Note: The switch logic with UNITROL 5000

-Operational control mode
constant voltage, constant current, constant reactive, constant power factor

- Sound Monitoring, restrictions and protection
See"ABB UNITROL F automatic voltage regulator device and its application"

- Hand-speaking local controler(UNS0874)
Hand-speaking local control UNITROL®F/5000, connect the control module through Serial RS485
