Diagnosis and Treatment of Low-Frequency Vibration of the Exciter of 300 MW Generation Set 300MW机组励磁机低频振动诊断与处理
The mathematical model for the motion of CVE 2 type chaotic vibration exciter was set up and its numerical simulation and chaotic identification were carried out. 建立了使用滑动轴承的CVE-2型混沌激振器所产生的运动的数学模型,并对其进行了数值仿真和混沌识别。
The problem of high shaft vibration during generator rotor's 2nd critical speed and exciter rotor's 1st critical speed was always existed since the No. 1 turbine-generator set was commissioned in 1996. The vibration affected the operation of load regulation seriously. 1号汽轮发电机组自1996年投运以来一直存在发电机、励磁机转子通过其临界转速区域轴振动大的问题,严重影响其调峰运行。
