Registration Date 21-01-2026 Organization National Technical University "Kharkiv Polytechnic Institute" popup.description1 The goal of the project is the development of an underground electrical network with a voltage of 110/35/10(6) kV, which will make it possible to significantly increase the reliability of electricity supply to consumers of electricity. Tasks to be solved by the project: - protection of electric network equipment from missile strikes and man-made threats (both due to natural phenomena and caused by the human factor); - increasing the environmental friendliness of electrical networks and reducing its negative impact on the environment; - justification for reducing the size of the substation due to the optimization of distances between current-conducting elements; - development of a power transmission line with air insulation placed in an underground collector; - increasing the throughput of power transmission lines due to changes in its design; - reduction of electrical energy losses due to reduction of the required number of lines for its transmission; The execution of the substation underground in a reinforced concrete shelter will allow to protect the equipment of the PS from external attacks (including from missile attacks). In the case of such placement, the probability of damage due to external influences will be significantly reduced. - reduction of electrical energy losses due to placement of underground substations of higher voltage closer to consumers; - research on the possibility and conditions of improving the design of insulating elements of the electrical network placed underground; - simplification of substation protection systems against overvoltages; - increasing operational reliability of power transformers due to improvement of diagnostic methods; - reduction of necessary equipment to ensure operational reliability. popup.description2 The project is dedicated to developing a methodology for achieving partial The idea of the project is to ensure a stable, reliable and efficient energy supply, for this it is proposed to develop a technical and economic justification for theconstruction of a 110/35/10 kV substation underground. Making the substation underground in a reinforced concrete frame will protect the substation equipmentfrom external factors that can cause the equipment to fail. In addition, the reinforced concrete frame will reduce the negative impact of the substation on theenvironment (electromagnetic radiation, noise). The possibility of reducing the overall dimensions of the substation due to the convergence of current-conductingelements without the use of elegas, only with the help of air insulation, will be scientifically substantiated. Marketing research was carried out in the work, whichallows us to draw conclusions about the possibilities of implementing the development both in Ukraine and in other countries. Ways of combining an undergroundsubstation with other buildings and structures are proposed, which will simplify operation and reduce capital investment in the construction and maintenance ofsuch a substation.
