Monitoring of steam turbine blade state from the relative rotor vibration signals

Original language description

The shrouded or bandaged blades are more and more often used in turbomachines of large capacity, mainly in steam turbines. To avoid accidents with extensive economic losses, there appears an urgent need to equip at least every stage of low pressure turbine with modern measuring system that would provide information of blades loading in turbine operation, their damage and residual lifetime. This paper summarizes the current approaches and methods, and shows directions that are currently addressed in thefield of research and development. As a new research direction, the paper describes a method for monitoring of the moving blades state from standard signals of mounted relative rotor vibration signals.
