SKV40 wood chips — UPS
Background: DONG Energy Thermal Power is building a new district heating production plant (SKV Wood Chips) based on two wood-chip boilers, providing steam for existing steam turbine and/or standalone bypass heat exchanger. The two boilers are envisaged as an add-on to the existing gas fired plant, Skærbækværket. The new biomass fired boilers shall deliver up to 320 MW heat to the district heating system. It is envisaged that the new boiler plant shall have a capacity of maximum 280 MW and the remaining 40 MW will be provided by flue gas condensers.
Uninterruptible Power Supply (UPS) equipment:
The add-on plant shall be equipped with new emergency power system, UPS and batteries. The emergency power system shall be with full redundancy and placed in separate electrical operating rooms.
New main distribution of emergency power system will feed the different contractors sub-distributions, such as boiler and bag house. New emergency power system will be separated to the different contractors sub-distributions, which will be placed in near vicinity to their Works. New emergency power system is planned to be placed in an electrical building at/in the boiler house.
The final design of the new emergency power system is not set. Alternative solutions regarding the interface, up- and downstream, of the new emergency power system are investigated.
Feed of the UPS will be from the new low voltage distribution, 3-phase 50Hz 400/230 VAC. Prospective short current levels for the new main distribution of low voltage switchgear are Ik > 50 kA.
The following values are valid for the distribution of low voltage emergency power system, with earthing system TN-S:
— Emergency power distribution 400/230 VAC.
Electrical operating rooms will be arranged with measures to control the environment and will be fitted with installation floor.
