Abstract
One of the most important topics of offshore
Wind Power Plant (WPP) installation is the wake effect of the wind turbines on
each other. This situation reduces annual energy production of WPP. WPP
installation should be performed by considering the loss of production due to
the wake effect. Nowadays, many methods are used for calculation of wake
effect. Among these methods, the Jensen method is mostly preferred due to the
simple and high degree of accuracy. In this study, Wake effect between two wind
turbines is modeled by using Jensen method for variable wind velocities and
frequencies at the same elevation in a region. The model is formed in the
Matrix Laboratory (MATLAB) software development environment. Also, Wind Atlas
Analysis and Application Program (WAsP) software is used to verify the former
model. In this software, two wind turbines are placed in offshore region. In
this case, gross and net production values of turbines were calculated. When
the results of MATLAB and commercially used WAsP model results were compared,
the approximately same production values were obtained. These results show that
the developed model can be used in calculations in offshore WPP.
