Abstract
A designing method of a wind turbine rotor includes: providing operation environment data indicative of an operation environment of a wind turbine generator including the wind turbine rotor and design data of the wind turbine blade; calculating a position of a center of mass of the wind turbine blade in each position in a lengthwise direction of the wind turbine blade in the operation environment from the operation environment data and the design data; and calculating an evaluation value which is a value depending on an integral value obtained by integrating a product of the calculated position of the center of mass of the blade and a mass per unit length at each position in a lengthwise direction of the wind turbine blade from a blade root portion of the wind turbine blade to a blade tip end of the same.
