The steam flow excited vibration(SFEV) is one of the key factors which restrict the safety of ultra-supercritical units.The status quo of studying SFEV at home and abroad has been briefly analysed
the causes leading to SFEV on steam turbine of ultra-supercritical units
the behavior of SFEV
and the influence of SFEV upon stability of the shafting system being presented.Combined with the practical examples of vibration on ultra-supercritical unit in one power plant
the SFEV on steam turbines has been analysed and discussed
and measures for rectifying SFEV on steam turbines being given
