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 invention relates to a division method and device for the running state of a wind turbine generator system. The method comprises the steps that the running interval of the wind turbine generator system is determined according to the relationship of revolving speed and wind speed in the wind turbine generator system data collected in advance, and an analysis data set is built; according to theanalysis data set, the division threshold of the running state of the wind turbine generator system is determined; according to the threshold, the running state of the wind turbine generator system isdetermined. Through the technical scheme, it can be achieved that the running state of the wind turbine generator system is divided.
Description
Technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a method and a device for dividing the operating state of a wind turbine. Background technique [0002] The direct energy source of wind power generation 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 power is realized by constructing a physical model of the wind power plant. However, in actual engineering, it is found that there is a certain calculation deviation in the results obtained by using this method. By analyzing the relationship between wind turbine wind speed and actual power, it is found that under the same wind speed level, the output of wind turbine generators is different, indicating that the operating state of wind turbine generators is not affected by wind speed. In addition to the impact, it is also affected by other factors. The combine...
