Two-parameter wind turbine cabin transfer function construction method, system, equipment and storage medium

Abstract

The invention provides a two-parameter wind turbine cabin transfer function construction method, a system, equipment and a storage medium. The method comprises the following steps: selecting a benchmark wind turbine generator, measuring free incoming flow wind speed, and obtaining cabin wind speed and wind turbine generator output power data in the same time period to form a data set; and performing data validity and wind turbine generator running state validity recognition and data processing on the data set, and further establishing a two-parameter cabin transfer function relationship among the free incoming flow wind speed, the cabin wind speed and the wind turbine generator output based on a curved surface fitting method. A cabin transfer function of the wind turbine is adopted, consideration factors of the transfer function are added from a model mechanism, and the problem that free incoming flow wind speed parameters needed by operation control and performance evaluation of the wind turbine under the flat terrain condition are missing or the estimation accuracy is low is solved. Meanwhile, the dependence on a remote sensing wind measuring device during post-evaluation of the wind turbine generator is reduced, and a practical solution is provided for operation control optimization and energy efficiency performance evaluation of the wind turbine.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a construction method, system, equipment and storage medium of a dual-parameter wind turbine nacelle transfer function. Background technique [0002] In wind energy engineering, free flow refers to the natural air flow in front of the wind turbine that is not disturbed by the rotation of the impeller. The free flow wind speed is an important basis for the evaluation of performance parameters such as the operation of the main control system of the wind turbine and the power curve. However, during the operation of the wind turbine, the wind speed at the unit point is usually measured by the nacelle anemometer located at the tail of the nacelle behind the impeller, and then recorded in the wind turbine monitoring and data acquisition system (SCADA). Practice has shown that due to factors such as the shape of the nacelle and blades, impeller speed, blade pit...
