Problems solved by technology

Since each part of the wind turbine needs to install various types of sensors at the same time, and sometimes two or more types of sensors need to be installed at the same time in a certain position, the parameter monitoring system of the wind turbine is very complicated and the cost is also very high. high
[0004] In addition, the types of parameters that can be monitored by traditional wind turbines are also limited, such as torque, thrust, blade bending moment, blade twisting moment, tip offset, etc. displacement), tower bending moment (tower bending moment), three-dimensional motion track (three-dimensional motion track) and other parameters cannot be monitored at present, or even if it can be monitored, it is very complicated

Abstract

The invention relates to a wind turbine and a method for monitoring a parameter thereof. The wind turbine comprises a blade, a miniature inertial measurement unit mounted on the blade and a parameter processing unit, wherein the miniature inertial measurement unit is used for sensing a parameter signal at a corresponding mounting position, and the parameter processing unit is used for receiving the parameter signal sensed by the miniature inertial measurement unit and calculating a corresponding parameter.

Description

Technical field [0001] The present invention relates to a wind turbine and a method for monitoring parameters of the wind turbine. Background technique [0002] With the increasing awareness of environmental protection, more and more countries have begun to vigorously develop clean energy, wind energy is one of them, and the use of wind turbines can convert wind energy into electricity. In order to maximize the conversion of wind energy into electrical energy, it is usually necessary to monitor the parameters of various parts of the wind turbine in real time during the operation of the wind turbine, such as blade pitch, blade rotating speed, yaw, and rotor. Speed ​​(rotor speed), generator speed (generator speed), structural vibration (structural vibration), etc., and then output these parameters to the back-end controller, and the back-end controller adjusts the corresponding parameters of the wind turbine according to the obtained parameters, such as Adjust the yaw angle, roto...
