摘　　要：根据大量的现场试验结果 ,论述了某国产 30 0MW汽轮发电机组振动爬升与低频振动的特征及其原因 ,提出了消除机组振动爬升与低频振动的技术措施。实施这些技术措施后的现场试验结果表明 。On the basis of numerous test data obtained on site the authors expounds the characteristic features of climbing and low frequency vibrations in a Chinese made 300 MW turbogenerator set and the causes of their emergence. Some technical measures have been recommended for their elimination. The on site test results obtained after the implementation of these technical measures indicate that the measures adopted have been very effective in eliminating the above mentioned vibrations.
