Аннотация: One of the important subsystems of any power plant is the power output scheme, which determines reliability, economy, and safety of service, ease of operation and layout of electrical equipment. Reconstruction is carried out at the existing power plant and the withdrawal of part of the equipment in the reconstruction weakens the reПоказать полностьюliability of the circuit as a whole. Therefore, this process requires careful analysis to ensure the necessary reliability of the remaining part of the scheme and to increase the values of the parameters of the updated scheme upon completion of the reconstruction.?Existing methods for assessing reliability are reduced to the study of reliability during design and (or) operation, therefore, it is necessary to take into account the following factors during the reconstruction: increased wear on electrical equipment, an increase in the likelihood of energy security threats to the region, a lack of investment, the need for reconstruction on the operating scheme for power output of the power plant. Consequently, the development of a refined and improved method for analyzing and calculating reliability assurance in the management of reconstruction is a topical task for the station's power distribution scheme?
