大型电站性能与振动远程监测、分析与诊断网络系统的建立在我国还是首例，文中介绍了该系统的基本硬件构成和中心站软件系统的设计与实现方法。系统实现了大型电站中热力系统、锅炉、汽轮发电机等设备运行状态的远程监测分析与故障诊断，以及机组经济性能分析与寿命管理等。该系统已经在山东省电力科学研究院的远程诊断中心中实际应用。 The establishment of long-distance monitoring, analysis and diagnosis network system for large-scale power plant performance and vibration is still the first case in our country. The paper introduces the basic hardware constitution of this system and the design and implementation of software system of central station. The system realizes long-distance monitoring, analysis and fault diagnosis of the operation status of thermal power systems, boilers, steam turbine generators and other equipment in large-scale power stations, as well as economic performance analysis and life management of units. The system has been put into practical application in the remote diagnosis center of Shandong Electric Power Research Institute.
