Oulun Energian kaukolämpöverkoston ja -tuotannon kehitys vuosina 2006 - 2020

Abstract

Tässä diplomityössä on tarkasteltu Oulun Energian kaukolämpötoiminnan kehitystä lähitulevaisuudessa. Työn yhteydessä selvitettiin nykyisessä tilanteessa mitoituslämpötilaa -32 oC vastaava tehotilastollisen analyysin avulla ja laadittiin kasvuennuste kaukolämmityksen tehontarpeesta seuraavalle viidelletoista vuodelle. Kasvuennusteen perusteella on tehty tarkastelu kaukolämmön varatehon riittävyydestä. Verkoston tehonsiirtokykyä nykyisissä ja tulevaisuuden kuormitustilanteissa on tarkasteltu Process VisioninGrades Heating -verkostolaskentaohjelmiston avulla. Tarkastelun perusteella kaukolämpöverkoston siirtokyky on kohtalaisen hyvä. Verkoston ongelmakohtia ovat länsi-itäsuunnassa olevat siirtolinjat. Varatehon määrä tulee laskemaan lähivuosina alle suositeltavan määrän, mikäli uutta lämmöntuotantokapasiteettia ei rakenneta. Alkuvaiheessa paras ratkaisu tilanteen korjaamiseksi olisi uusien lämpökeskusten rakentaminen sekä kaupungin etelä- että itä-osiin. 2010-luvulla tarve uuden voimalaitoksen rakentamiselle kaukolämpötehon tarpeen kattamiseksi tulee kasvamaan. This thesis studies the development of Oulun Energia's district heating network and the production of district heating in the near future. The demand of the district heating power in dimensioning temperature of -32 oC was obtained using statistical analysis. Furthermore, a growth forecast of the district heating power demand for the next fifteen years was prepared. Part of the thesis was to examine the adequacy ofthe reserve heating power capacity in the near future. This was done on the basis of the growth forecast of the district heating power. The transfer capacity of the district heating network was studied in current and future load situationsusing Process Vision's Grades Heating network computation software application. Based on the analysis, the transfer capacity of the districtheating network is rather good. The problematic transfer pipelines are the onesthat run from west to east. The amount of reserve district heating power will drop under the common recommendation, if new capacity is not going to be built. At the beginning the best solution is to build new heating centres to the south and the east regions of the city. On the next decade the demand for a new power plant to satisfy the need of district heating power will grow.
