Scientific school “Scientific bases of development of control systems of thermal power objects of industrial enterprises and small energy” develops acting. Head of the Department, Doctor of Technical Sciences Volodymyr Voloshchuk together with Professor Yuri Kovryho, student and follower of the founder of the school prof. Kocho VS

The scientific school begins its formation from the moment of creation of the department of ATEP in 1958. The founder of school – prof. Valentin Stepanovich Kocho. Under the influence of the tendencies of industrialization of Ukraine in the beginning of 60th years the scientific direction of management of processes of energy consumption is formed. Research interests of prof. V.S. Kocho covered the problems of high-temperature control and management of metallurgical processes. He and his students were engaged in modeling heat and mass transfer in steelmaking units, optimizing fuel combustion, purging metal with oxygen, continuous control of metal temperature in open-hearth furnaces and oxygen converters. Among his students were well-known scientists: Academician Naidek VL, Corresponding Member Pereloma VA, Professors Antosyak VG, Revun MP, Eroshenko VA and other.

In 1980, Prof. was elected head of the ATEP department. Azhogin Vitaliy Vasyliovych, who expanded the scientific direction of modeling and automatic control of technological processes and CAD. According to the results of scientific research in this period a monograph, 3 textbooks were published, 1 doctoral and 14 candidate dissertations were defended, 15 author’s certificates were received, many implementations were made. VV Azhogin left many students, including: Academician Zgurovsky MZ, prof. Romanenko VD, prof. Novikov AN, Assoc. Movchan AP and other.

The follower of works in this direction became prof. Zaichenko Yuri Petrovich, who headed the department after the election of VV Azhogin to the position of rector of Odessa Polytechnic Institute. Yu.P. Zaichenko is the author of many publications and books, including “Operations Research” (1984, 1988) and “Structural Optimization of Computer Networks” (1986).

From 1990 to the present, the head of the ATEP department prof. Kovryho Yuriy Mykhailovych. Under his leadership, the scientific direction of modern computer technologies in energy is developing. At the initiative of Kovrygo Yu.M. The specialty “Computer-integrated technological processes and production” was founded and opened. Among the achievements of the scientific team of the department under the leadership of Kovrigo Yu.M. It should be noted the implementation of six state contracts under the resolution of the Cabinet of Ministers of Ukraine, including “Development and implementation of principles of construction, technical means and standard solutions for automation systems of municipal energy”, implementation of computer accounting and heat management for the Administration building Of the President of Ukraine, introduction of a full-scale simulator of the 300 MW power unit at Kyiv CHP-5, and introduction of the information and diagnostic system of the turbogenerator at CHP-6. Great attention Kovrigo Yu.M. pays attention to the formation of young scientists. He has many followers and students who worked fruitfully and work at the Department of ATEP, among them: Izgorev M.Yu., Bun VP, Grudzinsky YE, Tsymbalyuk EV, Fomenko BV, Bunke OS, Stepanets OV, Bagan TG and other. In recent years, the department has been fruitfully working prof. Ph.D. Tregub VG and prof. Ph.D. Smirnov VS

Application of exergy-based methodology for design, assessment and automatic control of thermal systems

The majority of the studies devoted to thermal systems are based on the first law of thermodynamics (the law of conservation of energy). The main drawback of this approach is that it fails to provide information about the real thermodynamic inefficiencies in a system. Heat transfer to the environment is the only loss identified with the help of this energy based approach.

Exergy based methodology using combined application of the first and second laws of thermodynamics is a new approach for design, assessment and automatic control of thermal systems. In contrast to energy analysis combination exergetic, economic and ecological methods of evaluation identify the location, magnitude, causes, costs and environmental impact of thermodynamic inefficiencies in an energy conversion system.

  • The Department develops methodological approaches to the exergy analysis of a building as a key element of heating system taking into account variations of operational modes due to influence of weather and climatic factors. Exergy-based design, assessment, optimization and control strategies are proposed within these studies.
  • The next research activity is devoted to development of methods and implementation of models (mathematical and computer) for combination of exergy, exergoeconomic, exergoenvironmental analysis, optimization and automatic control of heating systems and their single components.
  • The Department also provides an open, interactive calculation environment, which is based on the use of the Internet for the wide application of exergy-based modeling and optimization of thermal installations and systems. This environment supports the collection, storage, provision of data processing and uses the developed mathematical methods and algorithms.

Exergy-based methods are powerful tools for developing, evaluating, understanding, and improving energy conversion systems at both design and operational stages.

Research devoted to application of exergy analysis during the design process is  because it allows researchers to understand and source irreversibilities in a variety of different systems, hence influencing the design and future efficiency of the system.

It allows the researchers to optimize their design to make a more efficient system. In the past decade, due to improvements in computing technology and better understanding of computing algorithms, exergy analysis has increasingly been employed to optimize systems in the industrial, commercial, residential, and transportation sectors
