| Due to the field environment constraints, it is very limited to obtain the research data form wind farm which is used to research the wind turbine performances. The indoor simulation experimental platform effectively compensate for the deficiency to a certain extent. Thus, an experiment platform scheme of wind turbines is proposed, which simulate the performances of not only land wind turbines but also offshore wind turbines.The experiment platform consisted of the wind supply device, wind turbine rotor, generator, tower, floating platform, wave simulation device, sensor detection and data acquisition system. The structural parameter design of experimental platform was carried out. By establishing the force analysis model of the floating platform, the reasonable structural parameters were obtained. The PC running state monitoring system based on LabVIEW software was designed, too. Using the experimental platform, some investigations on dynamic characteristics of wind turbines were conducted. The tower vibration characteristics of land wind turbines and offshore wind turbines were analyzed. The experiment platform provided the foundation for the further study of wind turbine dynamic characteristics. |
