Abstract

The embodiment of the invention provides a method and device for determining a limit design load of a wind generating set and a computer readable storage medium. The method comprises the following steps: acquiring a limit design load of the wind generating set without gravity correction; according to the limit design load which does not adopt gravity correction, obtaining a limit driving working condition corresponding to the limit design load; determining a group of sub-working conditions including an limit driving working condition; and carrying out gravity correction on the loads of the group of sub-working conditions to obtain a limit design load after gravity correction. Therefore, the limit design load of the wind generating set after gravity correction can be evaluated more accurately and quickly, the working efficiency is improved, and the limit design load of the wind generating set is effectively reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wind power, and in particular to a method, device and computer-readable storage medium for determining the limit design load of a wind power generating set. Background technique [0002] With the gradual depletion of energy sources such as coal and oil, human beings pay more and more attention to the utilization of renewable energy. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. 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] During the design process of wind turbines, it is necessary to determine the vari...
