PHYSICAL QUANTITY SENSING APPARATUS OF WIND TURBINE BLADE, CONTROL APPARATUS, CONTROL METHOD AND RECORDING MEDIUM THEREOF

摘要

PURPOSE: A device for detecting the physical amount of a blade of a wind power generator, a blade control device, and a blade control method are provided to calculate the deflection of the blade by using an optical fiber Brag lattice sensor and temperature compensated optical fiber Brag lattice sensor. CONSTITUTION: A device(100) for detecting the physical amount of a blade of a wind power generator comprises an optical fiber(110) and a Brag lattice(120). The optical fiber total-reflects the light incident from a light source. The Bragg lattice reflects the lights of a Bragg wavelength band among the light sources transmitted through the optical fiber, thereby sensing a change in the physical amount of the blade. The sensed physical amount is one among the temperature of the blade, the strain of the blade, and the deflection of the blade. [Reference numerals] (AA) Epoxy molding
