News 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 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. Funen Power Station by night.

AUTOMATIC SYD A/S has in total designed, assembled and delivered 9 switchboards for Funen Power Station. 4 News 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.
