摘要
针对上海外高桥第二发电有限责任公司的900 MW超临界机组汽机转子振动实际情况,设计并开发了一套集振动参数和热力参数的在线监测与故障诊断系统。系统以VC++作为前台开发工具,以MS SQLServer作为后台数据库服务器,结合振动参数和热力参数耦合诊断规则,有效补充了单一振动数据诊断的不足。经过电厂实际使用证明,该系统运行稳定,分析数据可靠,提供数据信息充分、方便,为电厂机组安全稳定运行提供了依据。
According to the vibration state of the 900 MW supercritical unit of Shanghai Waigaoqiao No. 2 Power Generation Co. Ltd. , an on-line monitoring and fault diagnosis system based on vibration parameters and thermal parameters was developed. By using VC ＋ ＋ as its development tool and MS SQL Server as its database server, the system applied the coupling diagnosis based on vibration parameters and thermal parameters, which overcomes the shortage of diagnosis based on single vibration data. Practice showed that the system operated stably and could provide reliable data analysis.
