Increased availability thanks to new

SPPA-E3000 Drive Modernization
involved the replacement of the frequency
converters for the mill air fans at the Reuter
West combined heat and power plant. This led
to a significant increase in plant availability.
The Result
■ Increased availability
thanks to modernized
frequency converter
■ Lower auxiliary power
consumption due to
optimized closed-loop
control and recovery
■ Improved maintenance as a
result of stocking of spare
parts and timely servicing
■ Reduced capital investment
thanks to continued usage
of various principal
components (motor,
transformer, etc.)
■ Quick return on investment
The Plant
The coal-fired Reuter West combined heat and
power plant (CHP) is operated by Vattenfall
Europe Wärme AG. Commissioned in 1987 and
1989, the two identical units generate a total
output of 600 MW, making the plant the most
powerful in the Berlin area. Every day, some
3,300 tons of coal are consumed and more than
500,000 households are supplied with power
and heat.
The Task
The existing frequency converters for the
3 MW mill air fans had been in operation for
more than 20 years, and their recent frequent
outages had begun restricting the power plant's
availability. In addition, there were no spare
parts or technical service available for the
obsolete components, which meant that
reliable maintenance was no longer possible.
A new frequency converter was needed to
restore the original availability of the Reuter
West CHP.
Our Solution
SPPA-E3000 Drive Modernization allowed the
availability of the Reuter West plant to be not
only restored, but actually improved.
The scope of supply included the delivery of
a new frequency converter, dismantling of
old components as well as the set up and
commissioning of new components. The
converter transformers and high-voltage drives
were renovated and were able to be retained.
The new SINAMICS GL150 frequency converters
offer the continuing advantage of optimized
closed-loop control and energy recovery,
which means energy costs can be reduced –
a welcome side-effect.
Our comprehensive package of services met the
power plant's individual requirements in full,
which meant that Vattenfall Europe Wärme AG
could increase the availability of its plant quickly
and cost-effectively.
"Excellent collaboration
between the Vattenfall project
team and Siemens meant that
the project could be delivered
quickly and economically. The
frequency converters were
replaced very quickly and with
minimal commissioning effort.
The equipment supplied meets
our requirements perfectly and
plant availability has increased
considerably."
