Abstract [sv]

Energimätning och övervakning kan bidra till minskad energiförbrukning genom att hjälpa en användare att ta beslut över energianvändandet. Valet av examensarbete gjordes p.g.a. behovet att ge användarna möjlighet att påverka sin energiförbrukning och övervaka sina elprodukter. Ett koncept togs fram där toppvärden på spänning och ström, effektfaktor, spänning-ens vågform, aktiv, reaktiv och skenbar effekt mättes. Samtliga värden skickades till en server som lagrade informationen och innehöll en hem-sida för presentation. Användaren kunde därefter ta beslut om att stänga av eller på produkterna via hemsidan. Systemet kompletterades även med möjligheten att öka övervakningen med hjälp av externa sensorer. Ett re-sultat av arbetet blev en prototyp som demonstrerar konceptet, ett annat resultat var flertalet möjliga förbättringar som kan göras för vidareutveckl-ing av konceptet.

Abstract [en]

Energy monitoring can lead to lowering energy consumption. This infor-mation would help the user to make decisions in regards to the power us-age. The measurements can also give the user the possibility to study the power quality to find bad loads and minimize the effects on the power grid. The choice of thesis was done to give the users the possibility to affect and monitor their environmental effect in a way that is otherwise not possible. A concept was developed that measure the voltage and current peak, the voltage and current RMS, power factor and the voltage waveform. The measurements are then sent to a server that is also containing a website. With the website the user can monitor their power usage and turn on or off the power consumers on the website. Added to the system is also the pos-sibility to add external sensors to increase the monitoring. The result of the project is a functioning concept to demonstrate. Another big result is the amount of improvements discovered to make it a really good base to con-tinue developing on.
