Sammendrag
Denne bacheloroppgaven ble skrevet i samarbeid med Skjetlein VGS. Tittelen på oppgaven var”Styringssystem og energimanagment (vind/sol/vann)”. Skjetlein har mikro hydro, sol, og vindenergi fasiliteter. De ønsket å kombinere de 3 formene for fornybar energi til en egenmikronettverk, hvor energi produksjons data ble logført og vist frem grafisk for undervisning.Mikronettverket var sentralisert i Energi Hytta, hvor studenter ved skolen kan se de elektroniskekomponentene brukt, hvordan alt er koblet sammen, og en GUI som viser produksjon ogbatterinivå.Det første steget var å vurdere statusen til alle komponentene de hadde, og å vurdere hvilkekomponenter som manglet. En oversikt gruppen gjorde viste at sol-delen var nærmest å bliferdig, solcelle panelene var gamle men har verdt i brukt tidligere. Vind-delen hadde kun enturbin, alt annet måtte anskaffes. Til slutt, vann-delen hadde en vannturbin som alleredeproduserte strøm og et fungerende vannhjul som ikke var koblet opp mot noe. Etterpå ble det enevaluering for hver energi kilde (vind/sol/vann) angående hvordan best å benytte seg avtilgjengelig lokalitet og utstyr. Eksempelvis hvor man kunne plassere vindturbinen og hva slagsgenerator passer til størrelsen og RPM av vannhjulet.Etter en gjennomgang av hver energi kilde, gikk fokuset til utvikling av operasjonsplatformen.Inkludert et kontrollbord for det elektriske systemet, og software for insamling og visualisering avdata via GUI.Ved bachelorens slutt overrakte gruppen plantegninger for hele mikronettverk systemet,fungerende software kode som oppfylte kravende, og elektroniske komponenter som trengtes for ådrive mikronetverk. This bachelor was carried out in co-operation with Skjetlein VGS. Their title of the project pitchwas: ”Control system and Energy management for (solar/wind/hydro)”. Skjetlein has microhydro, solar and wind resource facilities. Their wish was to combine the 3 sources of renewableenergy into a micro-grid platform, where the power production is monitored so that the data canbe used for educational purposes through a graphical platform. The center of the micro-grid isthe Energy Hut, where the students can see the electronics used, how everything is wiredtogether, and a GUI that shows power production from sources and battery voltage level.The first step was to assess the status of the components on-site, and consider what componentswere missing for the system to be functional. It was decided that the solar part of the projectwas closest to working condition, the panels were old but had been in use previously. For thewind they only had the turbine, everything else needed, except the mast, the group would haveto procure. Finally, the hydro had a water turbine that was not connected but had already beenused to produce electricity previously, and a working waterwheel that was not connected toanything. Afterwards, an evaluation was made for each source (solar/wind/hydro) as to how bestutilize the available locations, such as where to place the wind turbine. As well as considerationsfor a missing components list, E.g. what generator would be needed to fit the size and RPM ofthe water wheel.After identifying the status of each energy source, the focus was on the development of theoperation platform. Including a control board with switches for the electrical system, a circuitboard for the electronics, and a software for collecting and displaying data on a GUI.Hence, finally at the bachelor’s conclusion the group handed over finished schematics for themicrogrid, working software code that suited the requirements, and the electronic componentsthe grid needed to operate.
