Abstract: ABSTRACT Demchuk Y.V., Kushchenko V.M. (supervisor), Construction of a closed substation of 110/10 kV "Nebrezh" in Kyiv. Master’s thesis. – Lviv Polytechnic National University, Lviv, 2020. Extended abstract. The closed substation of the 110/10 kV Substation "Nebrezh" is a high-voltage step-down substation operating with a high voltage of 110 kV. Thanks to a set of switchgear located inside the designed building, the load on the city network is reduced. This makes it possible to deliver electricity from high-voltage lines to urban residential buildings. This construction of the substation takes into account all the features of its purpose. Such features are specific equipment, location and special requirements for the structural part. I will note also bad characteristics of soils on a place of future construction. Study object – building of the closed substation of 110/10 kV Substation "Nebrezh" in Kyiv. Scope of research – design features in the calculation and modeling of the behavior of the object of study, taking into account all the initial conditions. Development of all necessary sections of qualification work on this object. Goal of research: to obtain estimated data in the design of this structure and analyze all the results we obtained. Make appropriate conclusions. The result of my work is this document, which developed sections on architecture, design, technology and organization of construction, as well as the economics of construction and research section. In the architectural you can see the spatial planning solutions and the master plan. In structural - the calculation of building structures: beams, slabs, columns, beams and piles. In technological terms, these are organizational issues during construction. In economic - the cost of construction work during their implementation. And in research it is a comparison of the work of a spatial model and a flat frame. After calculating and designing my object of study, I determined the necessary characteristics of the structures used in this building. Recommendations for the use of certain calculation methods. They also learned that the construction of the facility will take 148 days. The cost of the work is UAH 15,999,684. It should also be noted that when designing this structure with the help of calculation programs, a three-dimensional model was created, which includes the specified properties of the soil. This allowed to bring the calculation model as close as possible to the real building. All of the above can be found in this master’s thesis. More detailed information can be found in specific sections of this explanatory note, which should be considered in conjunction with the drawings.
