TY  - JOUR
AB  - For cost-effective connection of large-scalelong-distance wind energy, low frequency alternating current(LFAC) transmission scheme (16.7 Hz or 20 Hz) has beenproposed as an alternative to the conventional high voltagealternating current (HVAC) transmission scheme (50 Hz or 60 Hz)and recently popular high voltage direct current (HVDC)transmission scheme (0 Hz). The technical feasibility of LFACsystem has been demonstrated but the basis for identifying thedistance ranges for which LFAC would be preferable to HVACand HVDC has not been established and the dependence of thisrange on factors such as power transfer rating, voltage rating andcable/line type has not been investigated. This paper presents anin-depth analysis for the overall cost of LFAC system and thenprovides an extensive comparison with HVAC and HVDC, toexplore the distance ranges over which LFAC is cost-effectiveover both HVAC and HVDC in connections of offshore andremote onshore wind energy. The results demonstrate that LFACsystem does possess ranges in the intermediate distance for whichit is more cost-effective than both HVAC and HVDC, and itsoverall cost advantage is generally larger in the overhead line(OHL) connection of remote onshore wind energy than the cableconnection of offshore wind energy.
