Determination method and device for limit load of wind driven generator and readable storage medium

Abstract

The invention provides a determination method and device for the limit load of a wind driven generator and a readable storage medium. The determination method for the limit load of the wind driven generator comprises the steps of acquiring the standard bending moment of the wind driven generator; and determining the limit bending moment representing the limit load according to the limit bending moment modification function of the standard bending moment, wherein the limit bending moment modification function is acquired at least through least squares fit. The determination device comprises oneor more processors and is used for implementing the determination method. The readable computer storage medium stores a procedure, and when executed by the processors, the procedure implements the determination method.

Description

technical field [0001] The present application relates to the technical field of wind power, and in particular to a method, device and readable storage medium for determining the limit load of a wind power generator. Background technique [0002] Wind is one of the energy sources without pollution, and it is inexhaustible and inexhaustible. For coastal islands, grasslands, pastoral areas, mountainous and plateau areas that lack water, fuel, and inconvenient transportation, the use of wind power generation according to local conditions is very suitable and promising. Wind power generation refers to the use of wind turbines to convert the kinetic energy of wind into electrical energy. [0003] The ultimate load of wind turbines is very important in the design of wind turbines, and has a great influence on the strength design of structural components. At present, the ultimate load of wind turbines is generally estimated based on experience and numerical simulation, and the lo...

AI Technical Summary

Problems solved by technology

At present, the ultimate load of wind turbines is generally estimated based on experience and numerical simulation, and the load estimation at the initial stage of design is based on experience. The accuracy is low, and it is largely affected by the designer's own design experience.

Although the numerical simulation has high accuracy, it is very time-consuming and resource-intensive, especially not suitable for the situation where the design parameters are constantly modified and adjusted in the early stage of design, so it brings great challenges to the designer's design decision-making
