Assessment of Thermodynamic Efficiency of the Belarusian Energy System. Part 1

The energy system is one of the foundations a modern state, so, need for its successful development and functioning beyond doubt. In this regard, an objective assessment based on set indicators (viz. economic, thermodynamic) relevant. However, traditional operation carried out basis such characteristics as specific consumption conventional fuel electricity generation heat release, which does not provide comprehensive picture always applied correctly. article, first time exergetic method, calculation efficiency considered. use indicator makes it possible to obtain thermodynamic complex formation country in easiest way. As example, unified Belarus general condensing power plants particular have been analyzed fairly long period (2000–2021) various characteristic periods. method calculating described. results obtained are presented graphically. Attention paid issue acceptability error when generalizing data initial flows primary resources product centralized generating sources system. contribution total volume analyzed, most advanced them determined from point view. their was out; changes associated with commissioning Belarusian NPP were conclusion made that further reconstruction order reduce relative weight natural gas incoming part balance 50 % expedient. This can be achieved by increasing efficiency.
