Problems solved by technology
[0003] In the prior art, when determining the wind speed of the wind turbine, the wind speed of the wind turbine's nacelle is usually replaced by the wind speed at the hub of the wind turbine due to the harsh requirements, high cost, and long test evaluation time of the site where the wind measuring tower is configured. Free-flow wind speed, the accuracy is extremely low, resulting in inaccurate calculation of the power generation of the wind turbine

The invention relates to a wind turbine generator generating capacity determining method and device. The method comprises the steps of determining the equivalent wind wheel wind speed of a to-be-measured wind turbine generator in a measuring period according to the equivalent cabin wind speed of the to-be-measured wind turbine generator in the measuring period; according to the equivalent wind wheel wind speed of the to-be-measured wind turbine generator in the measurement period, determining the generating capacity of the to-be-measured wind turbine generator in the measurement period; obtaining the equivalent wind wheel wind speed through the equivalent cabin wind speed of the to-be-measured wind turbine generator, obtaining the generating capacity of the to-be-measured wind turbine generator according to the equivalent wind wheel wind speed, thereby improving the accuracy of the generating capacity of the wind turbine generator.
Description
technical field [0001] The invention relates to the field of new energy technologies, in particular to a method and device for determining the power generation of a wind turbine. Background technique [0002] In response to the energy crisis and environmental pollution, more and more people pay attention to renewable energy. Among them, wind power has become one of the fastest-growing and most promising new energy technologies due to its high utilization rate and mature technology. . The wind speed of the wind turbines and the generated power of the wind turbines in the wind farm directly affect the power generation of the wind turbines, and also pose a huge challenge to the operation of the power grid. Therefore, it is possible to accurately and efficiently determine the wind speed of the wind turbine and the generated power of the wind turbine, and obtain the power generation of the wind turbine to ensure the safety of the power grid. It is also an indispensable link in t...
