摘要
对 350MW机组一次调频时出现 1、2号瓦振动突然增大,振动保护动作跳机的问题,通过各种试验,分析查明振动原因,并加以解决,保证了机组安全稳定运行。
The vibration of the No.1 and 2 shafts jumped suddenly during the primary frequency modulation of the 350 MW unit and the vibration protection acted. To solve the above problem, various experiments were made and the reason of vibration was found out and settled and thus ensuring the stable operation of the unit.
