Based on many years of successful experience in developing and operating supercritical steam turbines with powers of 300 – 1200 MWand an analysis of advances in competing ultrasupercritical turbines, the firm JSC “Power Machines” has developed a 660 MWultrasupercritical steam turbine. The basic engineering solutions applied to the model K-660-26,5 turbine will be used to build a series of 500 – 1200 MW turbines with ultrasupercritical steam parameters. © 2015 Springer Science+Business Media New York Source

For Francis turbines operating at part load or over load a swirl flow arises behind the runner. Due to instability and/or asymmetry of the spiral casing a helical-like vortex rope appears in the draft tube. The goal of the present paper is to develop models of cavitating vortex rope and to evaluate influence of the gas/vapor phase on the pressure pulsation in the turbine draft tube and on the hydroacoustic characteristics of the system as a whole. © Published under licence by IOP Publishing Ltd.

Aspects of the vibrational state of blades and shaft lines during transitional operation of high-power steam turbines are examined. Measurements are made using a modernized version of the discrete phase method. It is shown that synchronization and load resetting do not lead to dangerous dynamical stresses in the blades and shaft components. © 2011 Springer Science + Business Media, Inc. Source
