Оптимизация надежности теплоснабжения с учетом функций активного потребителя

Abstract

The article considers the problem of analyzing and optimizing the reliability of heat supply to an active consumer (AP) of thermal energy in heat supply systems (HSS), taking into account their additional thermal power provided by their own sources of thermal energy (IT). The stated scientific and methodological problem consists in determining the optimal ratio of the values of the reliability parameters of the HSS elements (failure rates and / or restorations) and the power of the own IT AP, which ensures the required level of reliability of heat supply with minimal total costs to ensure the elemental reliability of the system and the operation of its own IT AP. The authors propose solutions based on the use of the theory of reliability, models of Markov random processes, some regularities of the theory of probability, nodal PN, models of the theory of hydraulic circuits and enlarged regularities of thermophysical processes occurring during heat supply to consumers. A computational experiment was carried out using the developed methods based on the TSS test circuit with characte­ristics close to real systems, providing the basis for conclusions and directions for further research.
