Background: The growing share of small-scale power generation, the limited access to foreign technologies and equipment, and the goals of the import substitution program make it quite urgent to choose and realize energy supply schemes of new industrial enterprises. The current researches are aimed at complex analysis of gas turbine engine efficiency for electricity, cold and heat supply of the industrial enterprises in Tyumen region. Materials and methods: To solve this problem, a comprehensive evaluation has been conducted including economic and territory-specific factors, the required level of reliability and mobility, the conditions for connection to the source of centralized power supply, and the main technical characteristics of the stations under study (diesel and gas-piston engine generating units, gas turbines, fuel cells, microturbines). Results: Gas turbine engines were proved to be effective for electricity, cold and heat supply of industrial enterprises. Criteria were formulated and structured for the most reasonable assessment and comparison of mini-CHP projects based on cogeneration and trigeneration cycles. A method of assessing the efficiency of decentralized energy supplies schemes was proposed. Conclusions: The results of the research enable investors to conduct technical and economic assessment of their own trigeneration systems implementation in accordance with the requirements. |
