Funen Power Station
By Jesper Fristrup and Gert Nielsen, CUBIC-Modulsystem A/S
AUTOMATIC SYD A/S, a CUBIC partner, has in 2009 supplied several Multi
Drawer switchboards for the new Unit
8 at Funen Power Station.
Funen Power Station
The history of Funen Power Station
dates back to the late 1940’ies where
the first company was established in
order to extend the electrical connections to ensure the supply of all Funen
from a new power station.
The power station was built over the
next four years and commenced its
generation of electricity for all of Funen
and district heat for Odense in 1953.
During the following 50 years, the po wer
station performed its task of operating
and expanding both the power station
and the electricity grid.
Today Funen Power Station has two
coal fired plants, a waste fired CPH
(combined heat and power) plant and
most recently a straw fired unit that
commenced production in late 2009.
It is for the new straw heated unit
AUTOMATIC SYD A/S has supplied the
switchboards. Funen Power Station is
today owned by Vattenfall, Europe’s
fifth largest producer of electricity.
Today, the primary task of the power
station is to convert the energy of the
fuel applied into electricity and district
heat. The electricity generated at
the power station is traded at ”Nord
Pool”, Europe’s largest and most
liquid marketplace for physical and
financial power contracts. The trading
of electricity is among other things a
consequence of the liberalisation of
the Danish electricity market in the
late 1990’ies.

The district heat is supplied to some
85,000 households and 7,000 institutions and companies in and around
Odense city.

Unit 8 - Straw fired CPH plant
In March 2007, the mayor of Odense
cut the first sod for a 750 million DKK
investment in a new independent
straw fired CPH plant with both boiler
and turbine. The boiler is designed for
burning various types of biomass.
The new investment clearly marked
Vattenfall’s commitment to a more environment friendly energy production.
The unit is placed in a new constructed
building and can, if needed, operate independently of the other units at the power
plant. The unit can, when fully operational,
handle 170,000 tonnes of straw annually
corresponding to 28 tonnes an hour.
At commissioning the environment is
set to be the winner. The new straw
unit will replace approx. 100,000 tonnes of coal and consequently reduce
the emission of CO2 by about 245,000
tonnes a year.
The electricity capacity at normal load
in unit 8 is 35 MW equal to 20 % of
the consumption in the nearby city
of Odense. The heat capacity of the
unit is 84 MW equal to 25 % of the
consumption in Odense.

Close to the unit, a straw storing facility
has been established with a capacity
of 2,300 straw bales weighing 580 kg
each. The straw arrives on truck from
farmers from Funen.
AUTOMATIC SYD A/S has in total designed, assembled and delivered 9 switchboards for Funen Power Station.

The Switchboards
AUTOMATIC SYD A/S has in total
designed, assembled and delivered 9
switchboards.
The package consists of:
• 2 switchboards for 690VAC/50kA,
each with 1600 A incoming section
and six withdrawable MD units.
• 2 switchboards for 400VAC/50kA,
each with 3200 A incoming section and
approx. 100 withdrawable MD units.
AUTOMATIC SYD A/S
AUTOMATIC SYD A/S is one of the
leading manufacturers of electrical
switchboards, automation and robot
solutions for the industry, OEM and
machine manufacturers and technical
electricians in Denmark and abroad.
AUTOMATIC SYD was established
about 25 years ago and is an order
manufacturing company with around
100 employees.
• The switchboards above the drawers for DOL (direct online) starters are
all equipped with ABB Universal motor
controllers, type UMC22.
• 2 switchboards for 220VDC, each
with 400 A incoming section and UPS
supply.
• 2 switchboards for 400VAC, each
with 125 A incoming section and UPS
supply.
Project manager Bo Jeppesen, Vattenfall, explains that he is very satisfied
with the CUBIC MD-system, as it
enables him to make extensions and
modifications without interrupting the
production.
All of the above switchboards are,
two by two, interconnected via a buscoupler in case of failure or maintenance in one of the incoming supplies.
The last switchboard is for 400VAC/
50kA with a 1000 A incoming section
and intended solely for lighting and
non-essential power in the building.
