Babenko I. The improvement and unification of the methods provision energy-saved of working supercharger on power plant station

The object of the research is the processes of providing energy-efficient operation modes of the power plant injection plants. The purpose of the research is to develop scientific methods and unified technical solutions aimed at reducing energy and fuel resource costs at thermal and nuclear power plants by optimizing the operating conditions of injection plants. Scientific novelty: the methods of mathematical modeling and analysis of characteristics and operating modes of power plant power plants have been further developed: for the first time analytical dependencies between the main operating parameters of the superchargers operation have been obtained by approximating their experimental characteristics and analytical functions, establishing the dependence of the energy losses in the superchargers on the main control parameters , Which allowed to ensure energy-efficient operating modes of superchargers; Has received further development of the solution to the problem of optimizing the operation modes of power plant injection plants by the criterion of minimum energy losses, taking into account the characteristics of hydraulic and aerodynamic networks and technological limitations, which made it possible to synthesize the unified structures of supercharger control systems; For the first time, universal analytical and graphical dependences of energy losses on the main regime parameters of injection plants, as well as unified dimensionless rotational speed dependencies on supply, have been obtained, which allowed to formulate appropriate regulatory recommendations for ensuring maximum efficiency of the superchargers.
