System for analysing and measuring production andefficiencies of cogeneration machine (CHP)

V današnjem času je vedno več pobud za rabo obnovljivih virov in virov z velikim izkoristkom. Pri tem imajo veliko vlogo naprave za proizvodnjo primarne električne energije, kjer prav tako izkoristimo sekundarno toplotno energijo naprave in jo uporabimo za pripravo tople vode. V diplomskem delu je opisana izdelava avtomatiziranega sistema meritev za naprave kogeneracije SPTE. Najprej so opisane okoliščine meritvenega območja in podjetje, ki izdeluje naprave kogeneracije. V nadaljevanju so podani vse naloge in postopki izvajanja meritev ustreznosti končnih naprav SPTE. Prvi sklop vključuje opis izbrane merilne opreme, projektiranje električnega vezja in povzetek omogočenih komunikacijskih protokolov. Drugi sklop naloge predstavlja metode izdelave programa, kjer so vključeni diagrami in opisi posameznih plasti različnih funkcij. Sledita analiza in obdelava podatkov v pripravi za poročila meritev. Podana so navodila za uporabo merilnega sistema in sklep naloge, kjer so opisane zadnje misli in možne izboljšave sistema merjenja kogeneracije.In today’s time there is an increasing initiative on renewable sources and sources with high efficiency. Cogeneration units with primary production of electrical energy and use of secondary heat energy for heating purposes play a big part in this category. In this thesis we describe the automation process of a measuring system for cogeneration units CHP. First, we describe the circumstances of the measuring area and the company which produces cogeneration units. Hereinafter there are presented all the tasks and implementation procedures of preforming measurements of the adequacy concerning terminal CHP equipment. First section includes descriptions of selected measuring equipment and devices, electrical circuit design and enabled communication protocols. The second section presents the methods of creating a program which includes diagrams and descriptions of individual function layers. This is followed by analysis and data processing in preparation for measurement reports. Instructions for the use of the measuring system are given, as well as the conclusion of the presented task where we present final thoughts and the possible improvements for the cogeneration measurement system
