中文摘要：

在风电场通过现场测试分析研究风力机性能由于受到现场环境的限制，能够获得的研究数据有限，室内模拟实验平台能够有效弥补研究不足。为此提出了一种海、陆两用风力发电实验平台方案。该实验平台由来风装置、风轮、发电机、两段式塔架、漂浮台、波浪产生装置、传感检测和数据采集系统等构成。在实验平台整体方案基础上，进行了结构参数设计，建立了漂浮台受力分析模型并获得了合理的结构参数，以 LabVIEW 为开发环境设计了上位机运行状态监控系统。最后，基于构建的实验平台，开展了部分风力机动态特性研究工作，对比分析了模拟陆地风力机和海上漂浮式风力机时塔架振动特性，为进一步深入开展风力机动态特性研究提供了基础。

英文摘要：

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.
