Balasanian G. Efficiency of the perspective energy supply integrated systems on the base of low-power cogeneration units (theoretical bases, analysis and optimization)

Dissertation is devoted to scientific and technical substantiation, to development and research of a new class of the combined units ? complex energy supply integrated systems (ESIS) on the base of low-power co-generation units and alternative energy sources, and to development of bases for construction of thermal schemes and processes of mentioned systems, for development of methods of their analysis, and for optimization of parameters and modes of functioning. In the work the comparative analysis of perspective directions of energy supply systems efficiency increase on the base of low-power co-generation units is executed, and rational thermal schemes of different configurations ESIS are offered. The author's analysis for substantiation of the criteria and methods of complex thermodynamic estimation, economic and ecological efficiency of integrated systems are carried out. Principles of construction of the mathematical models of ESIS is formulated, and mathematical models of its components combined with the alternative sources of energy with different variants of configurations, types of the systems, energy sources and modes of consumption of power products are executed. In the work the method of alignment the thermal and electric loads charts of ESIS depending on power potential of additional sources energy and thermal accumulation properties of system's elements is offered. The conclusion for increasing thermodynamic, economic and ecological efficiency of integrated systems based on comparing of co-generation systems combined with additional sources of heat and possibilities of limitations removal, that energy supply characteristic of the systems based on co-generation units and co-generation units with alternative sources of heat are made.
