AC Cable solutions for Offshore Wind Energy.
Copenhagen Offshore Wind International Conference 2005. Copenhagen, Denmark (26.-28.10.2005)
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
Different aspects of submarine AC cable systems for Offshore Wind Power will be presented. Advantages and disadvantages with 1-Core and 3-Core solutions will be discussed. For 1-Core solutions the possible rated power is significantly higher than for 3- Core solutions. One must however consider unbalance due to the un-transposed configuration and also make sure that galvanic corrosion will not be a significant aspect. A 3-Core solution will minimize the impact of these phenomena. The cable design will also decide its electrical parameters. Wind farms must comply to grid codes defining for instance operating voltage range and power factor in the Point of Connection to the onshore transmission grid. The working regions for the complete cable system in active and reactive power must therefore be investigated in order to optimize cable design, transformer data and required steady state shunt compensation. The paper will illustrate one possible way of describing the cable operating range for active and reactive power transfer. Reliability and exposure of the cable system is another aspect which is important to consider. Energizing of a cable can cause switching transients and resonances. On such example causing resonance is transformer magnetizing currents. The paper will show a few examples of energizing parallel cables and transformers.
