ABB UNITROL® 1000 automatic voltage regulators Compact and powerful

UNITROL 1000 provides compact and

reliable solutions. Various built-in control

software functions, robust mechanical

and electrical design enable a wide range of applications.

Systems include protection breaker and exciter field breaker.

They are fully tested in the ABB factory and AVR setting can be ordered preset.

Main features

• Compact and robust AVR for excitation current up to 20 A

• Separate communication and control processors

• Wide range of built-in control software functions

• Ethernet-based fieldbus interface

• Wide range of power input voltage, for AC and DC input

• Flexible and freely configurable measurements and inputs/outputs (I/Os)

Power system stabilizer (PSS)

PSS can be an option to provide standard IEEE 421.5-2005

2A / 2B / 2C function. The PSS provision is nowadays included

in most grid codes. The PSS is used for effective damping of

power oscillations caused by the physical power grid.

Software and tool for the UNITROL 1000 product portfolio:

All UNITROL 1000 products are based on the same target

software source code, therefore equal performance can be

seen with UNITROL 1010/20 as well as with UNITROL 1005.

The same simulation models can be used for the entire

UNITROL 1000 product family, making UNITROL 1000

products suitable for very demanding grid code applications.

ABB provides several levels of service for:

• Single channel systems

• Dual channel systems

• Mounting on a plate or in a cubicle
