The small wind turbine characteristics test

A small wind turbine characteristics test platform is designed and realized. It includes low speed opening wind tunnel, and data acquisition systems. The wind tunnel with 3.5m caliber is designed into direct-action wind tunnel, and its experiment sement is circular section. Multi-fans are adopted to provide wind energy in the power segment, which improves wind flow effective and reliability after wind flow pass through a celluar device. The data acquisition systems collect and deal with wind speed, wind turbine rotation rate, output voltage and current by data board. The test results for the small wind turbine prove the platform can meet testing requests of small wind turbine characteristics tests, which helps students to understand new energy using and enlarge knowledge.
