Embodiment Construction

[0051] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0052] The following will combine figure 1 An example of the design method of the wall thickness of the tower of the wind power generating set according to the embodiment of the present invention will be described. As an example, the determination of the wall thickness of the tower can be carried out after the height of the tower, the section conditions and the height of the weld seam have been determined.

[0053] As an example, the determination of the wall thickness of each section of the tower can be done separately. For each section of the tower, an optimization algorithm is used to determine the wall thickness of each section of the tower, wherein the optimization goal of the optimization algorithm is to minimize the quality of each section of the tower, and the constraint condition of the optimization algorithm is that each section of the tower ...

Abstract

A method and apparatus for designing the wall thickness of a tower of a wind turbine generator system, and the design method includes: for each tower, an optimization algorithm is adopted to determinethe wall thickness of each section of tower separately, wherein the optimization objective of the optimization algorithm is to minimize the mass of each section of tower, and the constraint conditionof the optimization algorithm is that the safety factor of the ultimate strength, the safety factor of the buckling strength and the safety factor of the fatigue strength of each section of tower satisfy the preset safety margin value. In the method and apparatus for designing the wall thickness of a tower of a wind turbine generator system according to an embodiment of the present invention, bysetting the optimization objective of the optimization algorithm of the wall thickness of the tower to minimize the tower mass, and setting the constraint condition to be that the safety factor of ultimate strength, the safety factor of buckling strength and the safety factor of fatigue strength of each tower satisfy the preset safety margin value, so as to ensure the tower to realize the functions required to be realized and reduce the cost of the tower.

Description

technical field [0001] The present invention relates to the field of wind power generation, more specifically, to a design method and equipment for the wall thickness of a tower of a wind power generating set. Background technique [0002] Towers and foundations are the main load-bearing components of wind turbines, and their importance becomes more and more obvious as the capacity of wind turbines increases. Taking offshore wind turbines as an example, the finishing and manufacturing costs of towers and foundations account for about one-third of the total cost of wind turbines, and the weight of towers is related to the frequency of the overall support structure, which affects the design of the foundation by the design institute. One of the indicators for inspecting fan manufacturers. This shows the importance of the tower in the design and manufacture of wind turbines. [0003] Since the main function of the tower is to support the mechanical parts of the wind turbine, t...
