description: The subject of the graduate qualification work is "The use of heat pump installations to optimize the operating modes of the Petrozavodsk CHPP". The work is devoted to the study of the effectiveness of the use of heat pumps to optimize the operating modes of the Petrozavodsk CHPP. The aim of the study is to determine effective schemes for switching on HPU of various types to improve the efficiency of the CHPP by creating a simulation model and calculating technical and economic indicators. To achieve this goal, the following tasks are solved: 1. To determine potential sources of low-grade heat, as well as potential consumers of this heat; 2. To propose schemes for including HPU of various types in the Petrozavodsk CHPP; 3. Create models of the CHPP power unit without and with HPU in the computer-aided design system (CAD) "United Cycle"; 4. To analyze the impact of the inclusion of HPU on the efficiency of the operation of the CHPP. In the course of the work, the expediency of using a HPU for the purpose of heating the return network water before the group of PSG TG No. 2 (scheme II - SCHP) and after the mixing unit of RNW and make-up water (scheme III - VCHP and AHP) at fixed values of fuel consumption and electricity supply, which allows you to save money. An analysis of the results of HPU integration was carried out on the basis of technical and economic indicators.
