Calculation of parameters of power plants for autonomous power supply systems

Abstract

Thanks to a number of achievements in the field of thermoelectricity interest in the use of thermoelectricity for the generation of electric energy was renewed. To solve a number of important problems, such as: generation and distribution of energy produced; optimization and rational distribution of capital costs in the construction sector, autonomous power supply systems are used, the core of which is a thermoelectric generator (TEG). Such interest is caused by the fact that such installations are the most economical due to additional generation of electric power and allow drastically reducing fuel consumption. However, the calculation of thermoelectric devices is accompanied by the difficulties, associated with the dependence of electrical and thermal parameters, little attention is paid in scientific publications to a detailed description of heat transfer processes through the nodes of a thermoelectric device, to estimates of the heat of cold / hot coolants and their effect on the operating mode of an autonomous power supply system. The article offers theoretical foundations for calculating the parameters of power plants for autonomous power supply systems and the method of automated calculation of parameters using automated systems for searching technical solutions at the stage of TEG search design.
