Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] The following figures are used for illustration and simplification of description, and only important details relevant to understanding the present invention are kept, other details have been omitted. In the drawings, the same reference numerals and symbols are used for the same parts.

[0040] figure 1 A schematic diagram of dynamic scanning of the blades 4 on the rotor 3 of the wind power generating set 2 and the wind tower 6 by using the long-distance laser ranging system 1 is described. Among them, the laser ranging system 1 is located at 60 to 200 meters on the windward side of the wind turbine. A series of beams 1-1, 1-2, ..., 1-n emitted by the laser ranging system intersect with the surface of the moving fan blades. The motion trajectory is exactly the profile 5-1, 5-2, ..., 5-n of the airfoil at different positions of the bl...

Abstract

The invention relates to an indirect type geometrical parameter measuring and performance optimizing method for a fan rotor. The method includes: a laser ranging system is used to perform dynamic scanning on multiple wing-shaped contour lines at different wing shapes of the rotor blades of a wind-driven generator set, geometrical analysis is performed on the measured contour lines to determine the geometrical feature parameters of the rotor blades and a fan tower drum, and accordingly fan performance can be optimized by regulating blade pitch angles.

Description

technical field [0001] The invention belongs to the technical field of wind field measurement and relates to a method for indirect geometric parameter measurement and performance optimization of fan rotors, which can be used to solve the problem of unbalanced loads of wind power generating sets. Background technique [0002] With the rapid development of new energy and wind power industry, the installation and ownership of wind turbines are increasing rapidly. However, in recent years, due to the unbalanced load of the fan rotor, problems such as blade friction, excessive vibration of the nacelle and tower, blade breakage, and transmission shaft failure have been on the rise. The unbalanced rotor increases the fatigue load of the unit and reduces It is an urgent problem to be solved to reduce the output and service life of the unit. [0003] The results of the wind field statistics and the aerodynamic simulation of the fan rotor blades show that: the main factor causing the...
