Example Embodiment

[0020] The present invention will be further described below in conjunction with the drawings and specific embodiments of the specification.

[0021] Such as figure 1 As shown, the method for identifying the ultimate load of a wind turbine generator set in this embodiment includes the following steps:

[0022] S01. At the beginning, establish the limit load database of the wind turbine, and each limit load characteristic and corresponding trigger logic are preset in the limit load database;

[0023] S02. Collect real-time data on the operation status of the wind turbine and wind resource data of the environment in which the wind turbine is located when the wind turbine is operating normally;

[0024] S03. Compare the data collected in step S02 with the trigger logic of each limit load in the limit load database. When the collected data is consistent with the trigger logic of a certain limit load, execute the corresponding control logic to control the wind The power generation group p...

Abstract

The invention discloses a limit load identification method for a wind power generator unit. The limit load identification method comprises the following steps: S01, starting, and establishing a limit load database of the wind power generator unit, wherein various limit load characteristics and corresponding trigger logics are preset in the limit load database ; S02, when the wind power generator unit normally runs, collecting running state data of the wind power generator unit and wind resource data of an environment where the wind power generator unit is located in real time; and S03, comparing each piece of data collected in the step S02 with the triggered logic of the corresponding limit load in the limit load database, when the collected data is consistent with the triggered logic of one certain limit load, carrying out load drop control on the wind power generator unit, and otherwise, continuously carrying out running according to a normal running logic. The limit load identification method for the wind power generator unit has the advantages of simpleness and convenience in operation, accuracy in control, active avoidance in limit load and the like.

Description

technical field [0001] The invention mainly relates to the technical field of wind power generation, in particular to a method for identifying the limit load of a wind power generating set. Background technique [0002] At present, the wind power industry is developing rapidly, and the power level and blade length of wind turbines continue to increase, making low wind speed wind farms more and more valuable for development. While the power generation of wind farms has been increased, the load of wind turbines has also continued to increase, and the cost has also increased significantly. During the wind turbine design process, the design of many components is mainly restricted by the magnitude of the ultimate load. At present, the design of wind turbines mostly adopts the forward design method, that is, the component results are designed according to the load calculation results. Such as the lengthening of the blade, the limit load of the whole machine is constantly increas...
