Problems solved by technology
However, in actual engineering, it is found that the results obtained by this method have certain calculation deviations. By analyzing the relationship between wind speed and actual power of wind turbines, it is found that at the same wind speed level, there are differences in the output of wind turbines. In addition to the influence of wind turbines, it is also affected by other factors. The combined effect of various factors makes the wind turbines present different operating states, that is, different power generation capabilities.

The present invention relates to a method and device for classifying the operating state of a wind turbine, which includes: determining the operating range of the wind turbine according to the relationship between the rotational speed and the wind speed in the wind turbine data collected in advance, and constructing an analysis data set; determining the operation of the wind turbine according to the analysis data set The division threshold of the state; determine the operating state of the wind turbine according to the threshold; through the above scheme, the division of the operating state of the wind turbine can be realized.
Description
technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a method and device for dividing the operating status of a wind turbine. Background technique [0002] The direct energy source of wind turbines is wind energy, so the current theoretical power calculation of wind power mainly uses wind speed as input data, and the theoretical power calculation of wind farm is realized by constructing the physical model of wind farm. However, in actual engineering, it is found that the results obtained by this method have certain calculation deviations. By analyzing the relationship between wind speed and actual power of wind turbines, it is found that at the same wind speed level, there are differences in the output of wind turbines. In addition to the impact, it is also affected by other factors. The combined effect of various factors makes the wind turbines present different operating states, that is, different power genera...
