Assessing the Current State and Determining the Capabilities of the Domestic Power Engineering Industry to Ensure the Modernization of the Ukrainian Power Generation Sector

The article highlights the problems of development of the Ukrainian power generation sector. The aim of the article is to assess and analyze the current state of power engineering in Ukraine and determine its capabilities to ensure the modernization of the domestic power generation sector. The analysis of technical and technological support for the existing power generating fleet in Ukraine by types of main equipment is carried out. It is shown that the main equipment in Ukrainian NPPs is of Russian origin, and that in TPPs and HPPs are both of Ukrainian and Russian origin. The activity of main enterprises in the power engineering industry in Ukraine producing equipment for all types of power plants, including steam hydraulic turbines, generators, boilers, diesel engines, electrical equipment, cables, etc., is considered. A map of technical and technological support for the power generation sector of Ukraine is created. The main problems that hamper the further development of the domestic power engineering industry are identified. It is substantiated that the main strategic direction of the development of the domestic power engineering industry is the maximum possible satisfaction of the needs of the electric power complex by designing and manufacturing its own equipment and minimizing the volume of imports. It is proved that with the gradual solution of the existing problems and with more complete and competent use of the existing potential of the Ukrainian power engineering complex, the development of the enterprises of the complex in the set direction is quite realistic

The Condition of and Structural Changes in the Energy Sector of Ukraine

The article is dedicated to the analysis of the condition of Ukraine’s energy sector and its structural changes in the period 2000-2016. The dynamics of electric power production in Ukraine and the world, as well as the capacity utilization factor are studied. There analyzed the structure of capacities and electric power production in Ukraine by types of generation: those of thermal power plants, nuclear power plants, combined heat and power plants, hydroelectric power plants, and renewable energy sources. The lifetime of the existing capacities is studied. Structural changes in the capacities and electric power production in Ukraine are investigated. It is proven that a tendency to reduce the electric power production in Ukraine, with a simultaneous increase in the world production, was observed; and that most of production capacities in the nuclear, thermal and hydropower sector have expired their design lifetime and require replacement or modernization. It is determined that the structural changes in capacities and electric power production in Ukraine in the period 2000-2016 were very low with the largest structural change in capacities and electric power production in the period under review taking place in the production of electricity from renewable energy sources, and a significant negative structural change – in the production of electricity in thermal power plants

The Structural Changes in the Economy of Ukraine and its Energy Intensity

The article is concerned with an analysis of structural changes in the economy of Ukraine in view of energy intensity of types of economic activity (TEA). On considering the main tendencies of development of Ukraine’s economy in 2000 – 2015, it has been proved that, unlike the world economy, its development is of more unevenly nature. In order to research structural changes in the domestic economy in the period from 2000 to 2015, the methodical approach consisting of a number of interconnected stages has been proposed. Using this approach: the structure of economy of Ukraine by TEA has been analyzed, the classification and structure of the TEA distribution by their importance have been suggested; the dynamics of TEA of Ukraine have been analyzed, the classification and structure of distribution of Ukraine’s TEA by dynamics of development has been proposed; a matrix of positioning of the TEA of Ukraine in the plane of «proportion – rate of change» has been built; the values have been calculated and directions of structural changes of TEA in economy of Ukraine have been defined; a characterization of the TEA of economy of Ukraine as to the degree of materiality of structural shift has been formed; the integral coefficients of structural shifts in economy for the studied period have been calculated; the classification of the TEA of Ukraine according to the level of energy intensity has been developed, the structure of economy by the energy intensity groups has been presented; the indices have been calculated and directions of structural shifts of groups with different energy intensity of TEA have been determined; the integral coefficients of structural shift of economy due to the groups of TEA with different energy intensity have been calculated; the general characterization of structural shifts of the TEA of Ukraine in 2000 – 2015 has been formed

The Substantiation of Priority Directions for the Structural and Technological Modernization of the Electricity Generation Sector

The article substantiates the necessity of the structural and technological modernization of the electricity generation sector of Ukraine in view of the promising directions of technological development of modern energy and the production sufficiency of domestic power engineering. A methodical approach to the selection of priority directions for structural and technological modernization of the Ukrainian electricity generation sector is proposed. The structural shifts in electricity consumption in the country are investigated. The production and consumption of electricity in the country, the specifics of regulation of daily “semi-peak” and “peak” loads, as well as seasonal fluctuations during the year are analyzed. The methods of base-load provision in the united energy system of Ukraine (UES), the level of flexibility of various types of power plants, the distribution of capacities for base-load provision in the UES by types of energy generation are analyzed. Comparison of the main recommended and actual parameters of the energy generation sector based on the data of 2016 is made, and the existence of significant unused reserves of electric power generation is proved. The possibility for optimizing the structure of the energy generation fleet is justified. The main structural measures for eliminating the problems of the national generation of electric power are identified. A comparative structural and technological characteristic of the sphere of electric energy generation is developed. There constructed a matrix of the positioning of technologies for generation of electric power by the adjusted operating expenses and capital investments as well as a matrix of comparison of technologies for generation of electric power by level of their development and level of market development. Comparison of advanced technologies for thermal generation of electric power until 2035 is made. There justified the choice of the list of technologies for electric power generation, which are expedient to introduce at Ukrainian power stations
