| titleOfInvention | A kind of wind turbine intelligent load-reducing blade and its working method |
| abstract | The invention discloses an intelligent load-reducing blade for wind turbines. Several groups of main beam piezoelectric fiber actuators are respectively laid along the blade span, and spring clips are arranged on the trailing edge side of the main beam, and the clamping parts of the spring clips are inserted into the first trailing edge deformation zone and the second Between the deformation zones of the trailing edge, several groups of trailing edge piezoelectric fiber actuators are clamped on the clamping portion of the spring clip along the spanwise direction of the blade. , so that on the basis of the traditional independent pitch load reduction method, the main beam bending-torsional coupling load reduction is added, the main beam piezoelectric fiber actuator drives the main beam deformation load reduction, and the trailing edge piezoelectric fiber actuator drives the trailing edge There are three main and passive load reduction methods for deformation load reduction, which can make up for the insufficiency of independent variable pitch load reduction methods, and greatly improve the flexibility and reliability of large wind turbines for load reduction. |
