ABB UNITROL 1020-0006 (3BHE030579R0006) Full Version Automatic Voltage Regulator (AVR)

Product Description

The ABB UNITROL 1020-0006 (3BHE030579R0006) is the FULL-feature model of UNITROL 1020 compact excitation controller, part of ABB UNITROL 1000 series. It is an integrated automatic voltage regulator for synchronous generators and synchronous motors, responsible for generator voltage regulation, reactive power control, limit protection and excitation closed-loop control. This full version contains complete function sets, more configurable logic and communication options compared with the basic UNITROL 1020-0003 variant, widely used for small and medium brushless excitation systems up to 50MVA.

FAQ

Q: What is the difference between UNITROL 1020-0003, 0006 and 0007?
A: 0003 = BASIC entry version; 0006 = FULL complete function set; 0007 = FULL plus PSS power system stabilizer for grid oscillation suppression.

Q: Can UNITROL 1020 work with external power stage?
A: Yes, it can match UNITROL 1000-PM40 power module to extend excitation current up to 40A.

Q: Can it replace old UNITROL 1005 / UNITROL 5000?
A: It can be used as a functional replacement, but CT/PT wiring, auxiliary power and control logic need re-commissioning with CMT1000.
