UNITROL® Control Upgrade
Extend your system's life time with minimal cost
As an option to extensive spare part
investments and maintenance programs,
ABB‘s Control Upgrades are time- and
cost-effective ways to improve the
performance and extend the life cycle
of operational equipment. As the leader
in the excitation technology ABB offers
competence and experience needed for
a successful upgrade of your system.
Legacy control platforms and related issues
An excitation system’s control platform comprises complex
hardware and software both of which are subjected to rapid
development that constrains the life cycle of the system.
The Control Upgrade is applicable on the following UNITROL
system types:
− − UNITROL 5000
− − UNITROL M
− − UNITROL C
− − UNITROL D
− − UNITROL P

Control Upgrade procedure
The content of the original control cabinet will be removed and
replaced by the new controller and its related devices. ABB
has designed a standardized control upgrade plate, which is
pre-assembled, wired and tested in the factory. The plate is installed and connected to the terminals wih the existing control
cabinet (see drawing).
In the converter cabinets the firing electronics are replaced
with the latest technology. The thyristors, busbars, snubbers
and fans are retained.
The new UNITROL standard software is adapted to support
previous converter types, thereby reduce engineering time. To
ensure full functionality ABB has tested the new firing electronics in combination with previous converter types such as
UNL10300 and UNL11300. As long as the equipment remains
in good condition, field circuit breakers, transformers, cooling
and bus ducts are unchanged.
Benefits
− − Long-term spare parts availability at lower price for the
control part
− − Long-term availability of engineering and support competences
− − Extremely fast, state-of-the-art control platform with optical
communication between boards and standardized software
development environment
− − New interfaces for enhanced functionality (control terminals
or control and converter cabinet)
− − Possibility to integrate excitation system in modern power
plant control systems
