[0038] figure 1 It is a schematic flowchart of a method for generating a wind speed index according to an embodiment of the present invention. like figure 1 As shown, the method for generating the wind speed index includes the following steps:

[0039] S101: Acquire historical wind speed data of the wind turbine in a predetermined period.

[0040] In S101, a large amount of second-level instantaneous wind speed data and minute-level wind speed data will be generated by the wind turbine during operation. Obtain historical wind speed data generated by the wind turbine in a predetermined period, where the predetermined period may be a time length of one year or two years, or the predetermined period may be set according to actual needs, such as 6 months. The historical wind speed data of the wind turbine may include at least one of second-level instantaneous wind speed data, minute-level average wind speed data, and minute-level maximum wind speed data. As an example, the sec...

Abstract

The invention discloses a method and a device for generating a wind speed index. The method includes: acquiring historical wind speed data of a wind power generating set within a predetermined period; calculating extreme gusts based on the historical wind speed data and design parameters of the wind power generating set parameters; use the extreme gust parameters to establish an extreme gust model; according to the historical wind speed data and the extreme gust model, generate the first wind speed derivative variable of the wind turbine within the predetermined period, A wind speed derived variable is used as an index representing the wind speed. The method for generating the wind speed index provided by the embodiment of the present invention can not only realize the representation of the wind speed, but also reflect the distribution and fluctuation of the wind speed in a predetermined period, and provide a method for predicting the failure probability of the wind turbine through the relevant index of the wind speed in the later stage. support.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and in particular, to a method and a device for generating a wind speed index. Background technique [0002] With the attention to environmental issues and the development of new energy technologies, more and more attention has been paid to wind power generation. Wind power is the conversion of wind energy into electrical energy, and its output is largely affected by wind speed. Fluctuations in wind speed will lead to fluctuations in the output of wind turbines, which in turn affect the power grid. For wind farms, the wind speed in a region is the status of wind energy resources in that region. One of the most important indicators of wind farms is directly related to the economics and development value of wind farms. [0003] At present, there are usually two ways to express wind speed. The first one uses wind speed frequency to express wind speed, which is mostly used in wind reso...
