Abstract
Taking the actual operation condition of a 200MW steam turbine as example
the temperature field of rotor has been calculated and analysed
the regularity of rotor surface temperature variating with time under different conditions being concluded and summarized. Thereby
a reasonable simplified finiteelement calculation mode for temperature field of steam turbine's rotor being obtained
making the calculation speed to reach a level of controlled degree
hence the problem of excessive time consumption by using finiteelement calculation method in online monitoring system for rotor stress of large capacity turbinegenerator set having been effectively solved.
