Kobzar K. Methods and agents for manufacturing and unit modernization of Turbogenerators rated 150-300 MW.

The object of research is the physical processes in the units of powerful Turbogenerators. The dissertation purpose is development of the new methods and tools in order to create and modernize powerful Turbogenerators rated 150-300 MW and a scientific substantiation of their effectiveness on the basis of mathematic and physical modeling and field experiment. The Methods of research are numerical, analytical and experimental methods in modeling of physical processes. Theoretical and practical results and innovation are as follows developed on the basis of physical processes modeling in the units of Turbogenerators, including at their modernization, methods and techniques to create a new and comprehensive modernization of the existing Turbogenerators to improve the reliability, energy efficiency, extension of the service life and improvement of individual capacity in existing dimensions. The subject and the degree of implementation: the results of the use in the educational and scientific processes of the National Aerospace University named after N.E. Zhukovsky «Kharkiv Aviation Institute" and the Institute of Mechanical Engineering Problems named after A.N. Podgorny National Academy of Sciences of Ukraine (NASU) is also recommended for use in the design and manufacturing at SE "Plant "Electrotyazhmash" powerful Turbogenerators rated 235 and 330 MW, as well as a prototype model of a new type of Turbogenerators TGV-550-2MU3. The effectiveness of the implementation: a comprehensive modernization of Turbogenerators rated 200-300 MW let increase the rated power per 10%. The effectiveness of existing units due to increasing of the installed power is increased per 5-10% and the real efficiency of the machine is increased per 0.3-0.5%. The sphere of usage: Turbogenerator equipment at TPP and NPP.
