- FIG. 29 shows a comparison result of the output of the conventional wind power generator and the wind power system according to an embodiment of the present invention.
- the predicted power output is shown compared to a conventional wind power generator (NREL's EMD turbine installed in California, USA (rotor diameter 77m)).
- NREL's EMD turbine installed in California, USA (rotor diameter 77m)
- the individual turbines subjected to the tailwind, where the maximum output occurs show similar or higher output compared to the general-purpose wind turbine.
- the pressure loss related to the generation of noise was found to be as small as 1/65 of that of the existing general-purpose turbine (260 Pa, based on the maximum pressure loss) (Reference: Li et al., 2020, Renewable Energy).
- the wind power generation system has fewer driving units than a conventional wind turbine, and has a simple structure, so that additional output improvement can be expected when a larger-scale turbine is used.
- the pressure loss directly related to the noise of wind power generation is 1/65 of that of the existing wind turbine of the same size (based on the maximum pressure loss), indicating that it has the strength of low-noise operation.
