摘要
基于美国国家仪器公司开发的LabVIEW图形化编程开发软件平台,研究设计了水轮机压力脉动、振动和摆度及空蚀等水轮机典型故障的监测诊断系统,利用LabVIEW强大的数据采集分析处理功能,设计了信号采集、信号分析、信号处理、结果显示及诊断信号的整体系统,建立了研究信号的谱图库,满足用户分析信号的多样性需求。该系统能够连续在线监测水轮机状态的信号特征,实时显示信号变化过程,根据采集信号的数据研究结果,结合水轮机故障发生机理和特点,快速地判断故障发生类型及部位,从而为水轮机的及时维修与保养提供可靠的依据和必要的信息,节省企业成本,提高企业效益。
Based on the development of National Instruments Company LabVIEW graphical programming development software platform, design tur- bine typical fault monitoring and diagnosis system, such as the turbine pressure pulsation, vibration and pendulum degree and cavitations erosion of software research system, with the help of LabVIEW powerful data acquisition analysis processing function, the paper designed tile signal acquisi- tion, signal analysis, signal processing, the results display and diagnosis signal of the whole system, established rosearch signal spectrum galleries and met the demand of analysis of the diversity of research signal. The system can continuously online monitoring state of the characteristics of tur- bine signal, and real-time show detected signals change processes, according to the acquisition signal data research combined with the turbine fail- ure mechanism and characters, quickly judge the faults of the type and parts, and then provide reliable basis and the necessary information for ma- intenanee, and then save the enterprise cost and improve enterprise benefit.
