IEC standard based virtual wind turbine mechanical load test system

In order to conduct a systematic test over the mechanical load of the wind turbine, load measurement principles and methods have been studied according to the International Electro- technical Commission (IEC) standard, and wind turbine test scheme has been proposed. Combined with modern virtual instrument technology, a practical and reliable system for wind turbine mechanical load test has been developed. In addition to collecting various wind turbine parameters, the system can also yield a series of curves and charts ruled by IEC standards such as the capture matrix, the relation between load and wind speed, the equivalent load and load spectrum.
