摘　　要：以某燃煤电厂1000 MW机组三大风机(一次风机、送风机、引风机)为研究对象,实现一套性能监测与智能预警系统。利用三大风机的实时数据、历史数据进行计算分析,对风机工作点及性能实现在线监测,同时在风机本体风道加装高频压力探头,利用测量的高频压力波对风机失速先兆进行预警。依据系统提供的预警信息,厂方运行人员可对在运风机进行实时调整,并基于风机状态进行检修,有效节约资源。Taking the three major fans(primary fan,blower and induced draft fan)of a 1000 MW unit in a coal-fired power plant as the research object,a set of performance monitoring and intelligent early warning system is realized in this paper.The real-time data and historical data of the three fans are used for calculation and analysis,and the working point and performance of the fan are monitored online.At the same time,a high-frequency pressure probe is installed in the air duct of the fan body,and the measured high-frequency pressure wave is used to warn the fan stall precursor.According to the early warning information provided by the system,the operator of the factory can adjust the fan in real time,and carry out maintenance based on the state of the fan,so as to effectively save resources.
