Communication and SCADA installations for processing signals from the wind farm, the 33 kV installation and the farm regulator Distribution boards to distribute 230 V AC and 220 V DC for the 33 kV installation and SCADA/communication equipment Splice boxes for terminating optical fibres from the wind turbines The interface between Energinet.dk and the Concessionaire is the 33 kV side of the 220/33 kV primary transformer, see figures 3 and 4. The Concessionaire owns up to and including the cable termination on the 33 kV side of the 220/33 kV primary transformers, including the 33 kV bays for the 220/33 kV primary transformers. 33 kV installations Connection to transformers Specifications for the 33 kV cable terminations on the transformers will be provided by Energinet.dk. Each 33 kV winding on the three 220/33 kV primary transformers will be fitted with eight outlets per phase, where one outlet is for an excess-voltage conductor, and one is to be connected to an own-consumption transformer. Thus it is possible to have up to six parallel 33 kV cables from the primary transformer to the busbars on the 33 kV connection installation (three from each of the two parallel-connected bus couplers). The Concessionaire himself must protect his own installations from overvoltage surge. 3.2 Maximum output on 33 kV windings 3.2.1 Distribution on the primary transformers The requirements for distribution of the turbine production are dictated by the load options of the three primary transformers. There is one 200 MW transformer on the KFA platform and two 200 MW transformers on the KFB. The transformers have the same structure and they each have a 33 kV winding and a 220 kV winding. In the fully built scenario, with a total turbine production of 600 MW, the output from the turbines is to be distributed with 200 MW ± 8 MW between the three transformers, when all three primary transformers are in operation. 3.2.2. Maximum number of connected wind turbines The facilities for transmission of power to shore (platform and export cables) are designed for a maximum rated power of 600 MW (from a 600 MW wind farm). No more than 600 MW must be
