| Abstract: | The present situation of monitoring and analysis of the shaft torsional vibration is discussed in this paper.The basic theory and the advantage of four|terminal network method are explained.And time pulse method which is widely used to measure the shaft torsional vibration is narrated summarily.Based on four|terminal network model and time pulse method,the hardware structure and system functions of the monitoring and analysis set are expounded in detail.The set integrates data acquisition with analysis,monitors the real|time state of torsional vibration,and analyzes the fault of torsional vibration on|line,which brings a short and long|term benefits to the safe operation of steam turbine generators. |
