摘要
相对带基本负荷的机组,调峰机组易受到更多的热冲击或冷冲击,因而更容易出现振动问题。分析了广东电网调峰主力机组135MW机组在起动中产生异常振动的主要原因,并给出了碰磨产生振动故障的判别方法及避免事故扩大的处理措施。
Compared with the unit taking basic load, the peakregulating units are more easily subject to hot and cold impact, hence, the problem of vibration is easier to occur on them. The main causes leading to abnormal vibration in startup process have been analysed, and judgement method for vibration trouble resulting from impactrubbing, as well as remedial measures for avoiding expansion of said trouble being given.
