A derivation of simulation model of offshore wind farm with losses and annual capacity factor considered

摘要

It is important to evaluate the losses and output power of a large scale wind generation system like an offshore wind farm. This paper presents analyses about the output power and loss characteristics of an offshore wind farm composed of permanent magnet synchronous generators (PMSG), power converters, and high voltage direct current (HVDC) transmission cables. Annual output power, system losses, and capacity factor of the wind farm are calculated for some typical regions whose wind speed data are expressed by the probability density distribution function obtained from Local Area Wind Energy Prediction System (LAWEPS) in NEDO homepage in Japan.
