09年上交大的硕士论文 本论文作者在对风电场监控系统进行实际调研后，以美国 GE 公司的1.5MW 变速变桨距双馈异步风力发电机组为例做为被监测对象，应用 美国国家仪器公司 NI（National Instruments Corporation）虚拟仪器技术 和 LabVIEW8.5 作为软件平台，尝试开发大型风力发电机组旋转机械状 态监测系统，并根据风力发电机组和风电场远程监控的特征，对监测系 统的通信方式进行分析比较后，选择通信方案。监测系统的目的是对采 集的振动信号通过曲线拟合、统计分析、频率响应等步骤进行定量分析，将数据以图和表的形式显示出来，并储存所有数据。经过对模拟输入振 动信号的分析处理进行仿真，验证了该风力发电机组旋转机械振动监测软件平台的可操作性，具有进一步开发和完善其现场应用的价值。 (Jiaotong University master s thesis in 2009 Wind farm monitoring system for actual research, the authors of the paper to the U.S. company GE 1.5MW variable speed pitch as the object to be monitored from the doubly fed induction wind turbine, for example, the application National Instruments NI (National Instruments Corporation) virtual instrument technology And LabVIEW8.5 as software platform, try to develop large-scale wind turbine rotating machinery like State monitoring system, in accordance with the characteristics of the wind turbine and wind farm RMON monitoring system System of communication compared to select the communications program. The purpose of the monitoring system are collected Set the vibration signal by curve fitting step quantitative statistical analysis, frequency response analysis, the data is displayed in the form of graphs and tables, and store all data. After the analog input vibration The analysis of the dynamic signal processing simulation to verify th)
