摘要：
During the normal operation of a 600MW turbine in a power plant, the temperature of no.2 bearing rises to the alarm value, which seriously affects the safe operation of the unit. The reason of bearing temperature rise is found by analyzing the change of steam exciting force, and the problem is solved by optimizing the governor valve sequence to diagonal admission mode.
