Popis: [Introduction] The paper aims to obtain the optimal layout of offshore wind farm and gain the maximum profit in the project life-cycle, it is high necessary to analyze its impact factors. [Method] The own developed application was used to compare the wake models between Jensen and Larsen, different superposition algorithm among wind turbines and the interannual variability of wind direction, this disquisition had combined the practical offshore wind farm case to analyse and provide the optimal layout. [Result] The results we obtained demonstrate that the interannual variability of wind direction is the most key factor to layout, followed by the different wake model, with superposition algorithm least. [Conclusion] This work provides some guidance for further project on choosing the optimal layout, thus the billions of dollars in losses caused by interannual variability of wind direction can be avoided in life-cycle of 25 years.
