Description

The efficiency of solutions for development of district heating systems (DHS) is assessed by the effective heating radius (EHR), which is the distance from the district heating source (HS) to the some node, behind which it is economically unprofitable to connect of new consumers [1–4]. The search for the optimal EHR is the one of the main problem for the design and development of DHS. Methods for determining the EHR for DHS are developed, taking into account ensuring of reliability of heat supply to consumers. EHR is such a length (distance) of a heat network from a district HS to a consumer, within which the district heat supply of a given consumer is economically more profitable than a distributed (autonomic) one. Thus, the search for EHR for different transmission heat pipelines connected to the considered HS determines of its operation zones in different districts of the city. In addition, to the main problem of the EHR search, the assessment of nodal reliability indices for each consumer is carried out, on the basis of which the obtained EHR solutions are corrected (if necessary). As a result, we can determine the zones of district heating in DHS, within the framework of which not only energy and economically effective, but also reliable heat supply to consumers is provided. The developed methodical ensuring was used in the development of an optimal heat supply scheme for the actual DHS of city.
The reported study was funded by RFBR, project number 20-08-00488 А.
