It has many types of tests, short test period and reliable test results. It has been widely used in scientific research and small wind turbine testing. In recent years, wind tunnel test technology has been greatly developed. Test methods and technical indicators are also constantly updated. Domestic wind power industry independently develops high-performance products, not only through wind tunnel testing It can be tested, and the necessary parameters must be obtained through wind tunnel testing during the development phase to guide subsequent research and development and optimization. But because of the original Some indicators in the technical standards are backward, and some new test items are not included. It is no longer sufficient to provide standardized instructions for the current test work. There are obvious differences in the test data of different wind tunnels. This part is specially formulated to standardize test methods and improve the quality of tests. Small wind turbine Part 3. Wind tunnel test methods 1 Scope This part of GB/T 19068 specifies the requirements for testing small wind turbines (hereinafter referred to as "units") in low-speed wind tunnels. And methods.
