Abstract

Abstract:

Only by using the annual average wind speed and wind power density to determine the quality of wind energy resources is not comprehensive enough in wind resource analysis, which can not reflect the output capability of the wind resource. Investigating the k value，which is the shape parameter of two-parameter Weibull distribution wind conditions,is to find out its inherent relationship with the wind energy, wind speed distribution and wind energy distribution. And further research is put forward to find out the relationship between the k value and the effective wind energy utilization for different Cp curves of wind turbine generators.The above research will supply a scientific guidance for wind resource assessment and wind turbine generator pre-selection during the consultation, decision-making, design and other stages of wind farm construction.

Key words: Weibull distribution, wind power, energy distribution, shape parameter
