Abstract

The invention provides a transfer function determination method, a wind regime detection method, equipment, a wind generating set and a readable storage medium. The transfer function determination method comprises the steps that on the basis of a computational fluid mechanics model of the wind generating set, a whole machine external flow field of the wind generating set is simulated so as to obtain simulated airflow fields, different simulated airflow fields correspond to different simulated incoming flow conditions of the wind generating set, and the simulated airflow fields correspond to different simulated incoming flow conditions of the wind generating set. The computational fluid mechanics model comprises a wind generating set model and a wind tunnel model, the wind tunnel model comprises a wind tunnel model area, the wind generating set model is arranged in the wind tunnel model area, and the wind generating set model comprises simulation wind measurement points; determining simulation wind speed measurement values and simulation wind direction measurement values corresponding to the simulation wind measurement points under a plurality of different simulation incoming wind conditions; and determining a wind speed transfer function and a wind direction transfer function of the wind generating set at the simulation wind measurement point based on the simulation wind speed measurement value and the simulation wind direction measurement value. The generating capacity of the wind generating set can be improved.

Description

technical field [0001] The invention relates to the field of wind power, in particular to a method for determining a transfer function, a method for detecting wind conditions, equipment, a wind power generating set and a readable storage medium. Background technique [0002] The measured wind speed and wind direction of the wind turbine are an important factor in the control of the whole machine. They not only directly determine the cut-in and cut-out of the wind turbine, but also indirectly affect the wind-facing effect of the wind turbine, which in turn affects the power generation of the wind turbine. . [0003] Wind speed and wind direction measurement equipment for wind turbines mainly include mechanical anemometers, ultrasonic anemometers and nacelle-type lidar anemometers. However, due to the high cost of the nacelle-type lidar anemometer, there is no basis for large-scale application. Therefore, wind turbines mainly collect wind speed and wind direction through the ...
