The paper aims to develop a mathematical model and to implement HPSUFGE characteristics optimization in order to increase energy efficiency and economic parameters of a station. Methodological basis of the conducted research lies in a systematic approach to HPSUFGE heating processes modeling taking into account thermodynamic and economic efficiency. Modern approaches to thermodynamic and economic analysis of technical systems underlie mathematic models. As a result of the scientific research an improved scheme of a binary HPSUFGE with a cascade cycle providing increase of geothermal energy utilization efficiency compared to a single-stage cycle has been developed; power fluids (organic coolants) of multiple-stage binary cycles providing efficient power generation at an HPSUFGE have been defined; performance assessment optimization of HPSUFGE characteristics has been done; it helped to define appropriate structural and technological characteristics ensuring thermodynamic and economic efficiency of a station; a mathematic model describing heat release from HPSUFGE has been developed; using this methodology HPSUFGE efficient heat release schemes for meeting heating supply demands have been defined.
