Оценка термодинамической эффективности энергосистемы Беларуси

Оценка термодинамической эффективности энергосистемы Беларуси

Abstract

Впервые на базе эксергетического метода и соответствующего эксергетического КПД проведена оценка термодинамической эффективности работы как для всей Белорусской энергосистемы в целом, так и для конденсационных электростанций в отдельности, за достаточно протяженный период с 2000 по 2021 г. за разные характерные периоды времени. Рассмотрена динамика изменения количественной оценки термодинамической эффективности энергосистемы Беларуси как за последние двадцать лет, так и за годовой, отопительный и межотопительный периоды 2021 г. Показаны изменения упомянутых показателей, связанные с вводом в строй Белорусской АЭС. Сделан вывод о целесообразности рассмотрения работ по дальнейшей реконструкции энергоисточников энергосистемы с целью достижения относительного веса природного газа в приходной части энергобаланса до значений не выше 50 % путем повышения ее термодинамической эффективности, снизившихся с вводом в строй Белорусской АЭС. This paper shows novel thermodynamic effectiveness assessment based on exergy method and exergy efficiency of the Belarussian power grid as well as separate condensing power plants from 2000 till 2021. Quantitative evaluation of trends in Belarusian power grid thermodynamic effectiveness over last 20 years as well as for last year and heating and non-heating seasons are given. The changes in the mentioned indicators with the commissioning of the Belarusian NPP are shown. It is concluded that future work on power sources modernization within the power system is reasonable and the aim is to lower natural gas consumption to 50% of all primary energy sources and to improve the power system thermodynamic efficiency, that had a light decrease with Belorussian NPP commissioning.
