摘　　要：在当前的技术条件下,电厂所采用的汽轮机轴系振动监测系统的信号容易被外界各种因素所干扰,由此造成监测结果的不稳定性。只有在有效排除外界的干扰因素,才能够准确的对汽轮机本体进行监测,保证机组能够安全稳定的运转。首先对VM600系统进行介绍,并且对其系统特点进行分析,之后从汽轮机轴系振动监测系统进行介绍,从而着眼于汽轮机轴系在监测中所面临的干扰因素的分析,再对汽轮机轴系的振动监测进行防干扰的对策研究。Under the current technical conditions,the signal of the turbine shaft vibration monitoring system adopted by the power plant is easily disturbed by various external factors,which causes the instability of the monitoring results.Only when external interference factors are effectively eliminated,can the main body of the steam turbine be accurately monitored to ensure the safe and stable operation of the unit.Therefore,the VM600 system is introduced first,and its system characteristics are analyzed,and then the steam turbine shafting vibration monitoring system is introduced,so as to focus on the analysis of the interference factors faced by the steam turbine shafting in the monitoring,and then the steam turbine shafting Vibration monitoring for anti-interference countermeasures.
