Introduction
IEC 61400-12-1[1] is an international standard for measuring the power characteristics of wind turbines. It stipulates that field measurements should be carried out in complex terrain.
Calibration is performed to obtain the flow characteristic relationship between the measurement location and the wind turbine under test.
In addition to the reference wind tower for the unit power curve, a temporary wind tower needs to be installed at the unit site before the wind turbine to be tested is installed.
The IEC 61400-12-1 method is often used in industrial practice, but it has the following disadvantages.
--- Analysis of the additional costs of the second wind tower and the results of the on-site calibration;
---Additional site calibration time within 3 months is required;
Before installing a wind turbine, a site calibration decision must be made.
These shortcomings have prompted the industry to look for alternative methods for field calibration. One alternative is to use numerical simulation to derive the airflow correction coefficient.
The wind speed at the wind turbine location is the relationship between the wind speed at the reference wind tower location.
In numerical field calibration, the airflow correction coefficient is calculated by numerical simulation of the flow.
Some disadvantages, but numerical field calibration also brings other challenges.
---Dependence on simulation models;
---Dependencies of model settings;
---Dependence on the professionalism of modelers;
---Quantification of model uncertainty.
