Formulas for calculating the dimensions of a dynamic low-frequency vibration damper are derived. The damper is designed as a circularly curved thin-walled plate. Bench tests demonstrated that the damper effectively reduces the amplitude of vibrations of the bearing of a high-power turbine-generator set in two directions simultaneously. © 2015 Springer Science+Business Media New York

UPS of Russia is a unique power system. Its operating conditions are quite different in comparison with power systems of other developed countries. In such operating conditions excitation control of synchronous generators plays not only technological role, but also is used as a powerful tool of voltage regulation and emergency automation for the security of reliability and survivability of power system. That's why in the power system of Russia special demands to the excitation control and in particular to the automatic voltage regulators and power system stabilizers are operating. According to the demands operating in UPS of Russia, all prototype models of excitation automatic controllers before installation in power system should pass the functioning tests according to the standard program approved by the key institutions of the power industry. In the report the conclusion about efficiency of an AVR certification technique applied in Russia, which ensures checking of a hardware representation of control law and allows to eliminate bugs of algorithmic and program character, is performed. The realized technique of certification of automatic excitation controllers in the conditions of physical model of power system and criteria of their efficiency estimation will be disputed during the meetings of IEC Maintenance Team No. 12 Excitation systems for synchronous machines (revision of the IEC 60034-16 series).

Practical experience with the introduction of honeycomb seals in the flow-through sections of 250-800 MW steam turbines with supercritical steam pressure is examined. The most widespread designs for shroud and end honeycomb seals used in the development of new turbine units are discussed, along with the modernization of existing steam turbine equipment. Test stand data on the relative flow rate and power characteristics of honeycomb, radial, and axial-radial seals are compared. Results are reported from thermal tests for evaluating the efficiency of installing honeycomb shroud seals in the high pressure cylinders of the T-250300-240 turbine units at the TÉTs-21 plant of JSC "Mosénergo" and the K-800-240-5 turbine units at the Perm GRÉS plant of JSC OGK-1. © 2014 Springer Science + Business Media New York.

The major equipment in the PGU-230 steam-gas unit at the Heller thermal power plant (Hungary) and its technical characteristics are described. The technologies for startup of the power production system of the steam-gas unit and for switching it from a steam-gas unit cycle to open cycle operation of the steam-gas unit and vice versa are discussed. The regulatory range of the power generation system and its maneuverability characteristics are determined. © 2010 Springer Science+Business Media, Inc.

Based on many years of successful experience in developing and operating supercritical steam turbines with powers of 300 - 1200 MW and an analysis of advances in competing ultrasupercritical turbines, the firm JSC “Power Machines” has developed a 660 MW ultrasupercritical 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.
