Method for measuring ice cover mass of blades of wind generating set

The invention provides a method for measuring an ice cover mass of blades of a wind generating set. The method is characterized in that optical fiber grating sensor arrays installed at roots of the blades are applied, and a temperature sensor is used for temperature compensation, so that strain at a measured position and a blade-root cross-section bending moment value can be acquired accurately, and thus the value of the ice cover mass of the blades can be computed accurately; and an optical fiber grating strain sensor is adopted, so that influences of a severe electromagnetic environment, high temperature during the daytime and low temperature at night on measurement results can be effectively avoided.
