UNITROL 6000 Medium is the fully customizable solution for any customer’s needs for any type of generator.

Tailor-made system

UNITROL 6000 Medium uses proven prefabricated functional

modules. With single/double channel configuration (additional

backup channel on request) and a wide selection of thyristor

bridge modules, the system can be configured to meet all field

data and availability requirements.

Main features

• Selectable redundancy for control, power module, cooling,

I/O, communication and auxiliary power

• Improved HMI

• 64-bit floating point CPU

• No restrictions regarding data scaling and range

• Fast and precise measurements and control scheme

• Compliant with international and local standards

• Complete range of functionality to cover any grid codes

Key benefits

Stable and reliable control of your machine

• Highly integrated and robust AVR for harsh industrial

environments. Stable and accurate regulation even with

highly disturbed voltages

• Fully configurable I/Os and measurement inputs and user

specific configurable fieldbus interface enable easy plant integration

Easy operation, monitoring and maintenance of the system

• Intuitive and user-friendly commissioning tool

Full support for grid codes

• Certified AVR according to German grid code including

verified simulation models, capable of analyzing dynamic

net faults (FRT)

• Built-in Power System Stabilizer (option), simulation models

and grid code studies available

Efficient product life cycle management

• Extended lifetime of your assets with minimum costs

Professional technical help always within your reach

• ABB has a service support network unmatched by the competition

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

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)

Small and medium Excitation and Automatic Voltage

Regulation system (AVR)

The UNITROL® 6000 Medium excitation systems are engineered

to meet individual operational and environmental conditions as

well as international and local standards.

MEGADRIVE-LCI drives and static starters

For more than 35 years ABB’s MEGADRIVE-LCI drives and static

starters have proven their maximum reliability and availability in

a wide range of industries and applications. The MEGADRIVE

LCI is the preferred choice when it comes to reliable and

efficient operation of gas-fire power plants.

Flexible automatic synchronizers

For over 50 years, SYNCHROTACT® has protected power plant

generators and substations from the potentially destructive

effects of current surges caused by paralleling in non

synchronized conditions. SYNCHROTACT 6 is the sixth

generation of this well-proven and popular technology. Over

22.000 SYNCHROTACT units have been sold since its

introduction, more than any other synchronizer on the market.

Around the generator solutions

The excitation system and synchronizer have a powerful impact on the

dynamic performance and the availability of the generator. They guarantee

the quality of the generator voltage and reactive power and therefore the

quality of the delivered energy from the power plant.

Compact automatic voltage regulator systems

The UNITROL® 1000 product family covers a wide range of

applications for voltage regulation tasks of a synchronous/

generator or motor up to 80 MVA. It sets a new benchmark

for the global industry with respect to functionality, reliability

and connectivity.
