Abstract: Novitskyi A.M., Kravets T.Yu. (supervisor). The study of the turbine operation within No. 2 power unit at the Khmelnytsky NPP with the K-1000-60/3000 turbine at intermediary loads. Master’s thesis. – Lviv Polytechnic National University, Lviv, 2022. Extended abstract. The development of Ukraine’s energy industry, over the past few years, has shown a lack of efficient ecological thermal power capacities, which has affected the economic development of the state [1, 2]. Due to the state of war, there is a significant shortage of electricity in the country, and tariffs for it have increased by 1.5-2 times. A powerful energy complex for the production, distribution and sale of thermal and electric energy has been created in the state. Centralized production of electrical energy, in the basic part of Ukraine’s load schedule, is carried out at NPP power units. Continued operation of existing equipment without the introduction of new technologies may lead to accidental accidents with corresponding consequences. In order to overcome the existing difficulties and troubles in the energy sector, it is necessary to introduce new energy technologies and improve the existing ones. Experimental studies of the operation of their equipment in variable intermediate operating modes are an important measure of effective operation of NPP power units. However, there are significant limitations to their implementation - both purely technical and financial or security. Therefore, it is relevant to solve important technical tasks aimed at researching the operation of the turbine unit of power unit No. 2 of the Khmelnytsky NPP with the K-1000-60/3000 turbine at intermediate loads in order to ensure high efficiency of its operation [3]. In this work, attention is focused on improving the operating modes of power unit No. 2 of the Khmelnytsky NPP at intermediate loads. Study object – technical and economic parameters of power unit No. 2 of the Khmelnytsky NPP at intermediate loads. Scope of research – the influence of technical and economic parameters of the power unit on the efficiency of operation of power unit No. 2 with a capacity of 1000 MW of the Khmelnytsky NPP. Goal of research – conducting a study of the operation of the turbine unit of power unit No. 2 of the Khmelnytsky NPP with the K-1000-60/3000 turbine at intermediate loads with the establishment of optimal parameters for its operation. In the first section of the work, the general characteristics of the basic thermal scheme of the second circuit of the turbo installation of the power unit with a capacity of 1000 MW of the Khmelnytsky NPP are given. The characteristics of the low-potential complex of the turbine unit, the deaeration unit of the regeneration system, the separation and intermediate steam superheating systems, the circulating water supply, etc. are presented. The second section presents the consideration of the start-up and adjustment of the equipment of the technical systems of the second circuit of the power unit of the Khmelnytsky NPP. In the same section, a thermal calculation was performed. Calculation of the efficiency of the K-1000-60/3000 turbine unit, as a result of which the main parameters of steam, water and condensate flows in the elements were determined. The internal power of the turbo installation was calculated. The third section is devoted to the economic part, in which the cost of producing a unit of electricity is calculated, and the economic assessment of the project’s effectiveness is determined. As a result of the calculation, it was established that the implementation of programs for monitoring the state of the equipment is an important condition for ensuring its reliable and safe operation during the entire period of operation. In the automation section, a system of automatic regulation of the turbine was developed and the selection of devices and means for its implementation was carried out [4, 5]. Keywords: nuclear power plant, power unit, nuclear reactor, steam turbine, mode of operation of a turbo installation. References. 1. Mykytenko V.
