Abstract :
HVDC transmission becomes more important for wind farms located over hundred kilometres from the shore. For offshore wind farms decoupled by HVDC transmission, frequency is a degree of freedom. State of the art for offshore wind farms is a 50Hz AC distribution grid. In this paper the effects of a higher line frequency on the main parts of an offshore wind farm are investigated. The main advantages and drawbacks are revealed and compared to a wind farm topology using a DC distribution grid. A loss calculation for a whole wind farm was done to highlight the opportunities and restrictions. Figure 1 shows an offshore wind farm with HVDC transmission.
