    • A wind turbine blade having a lightning protection function includes an outer shell, a spar arranged in a space inside the outer shell, a spar cap which is formed by a carbon-fiber plastic laminated member disposed on a blade root side and a glass-fiber plastic laminated member disposed on a blade tip side that are connected together, the spar cap supporting the spar to the outer shell, and a lightning protection unit. The lightning protection unit includes a receptor for receiving lightning which is provided in the outer shell on a side where the glass-fiber plastic laminated member is arranged, a down conductor which directs lightning current received by the receptor into the ground or the water, and a conductive metal member which covers the outer shell on a side where the carbon fiber plastic laminated member is arranged.

    • A load is based calibrate on data collected under wide observation conditions and promptly calibrate loads of a plurality of wind turbine blades. A load measuring apparatus is applied to a wind turbine in which a pitch angle of a wind turbine blade is variable. The apparatus includes a sensor for obtaining a distortion of the wind turbine blade; a load calculating unit having a function expressing a relation between the distortion of the wind turbine blade and a load on the wind turbine blade, for obtaining the load on the wind turbine blade by applying to the function the distortion based on measurement data of the sensor; and a calibration unit for calibrating the function based on the measurement data of the sensor obtained in a pitch angle range and a rotational speed range of the wind turbine blade in which a variation between maximum and minimum aerodynamic torques is equal to or less than a predetermined value.
