Ontwerp van een robuuste datalogger voor elektrische energie voor kleinschalige hernieuwbare energie-installaties in ontwikkelingslanden -
Mathieu De Zutter
Humasol VZW has designed some small-scale renewable energy facilities, including
hydro-turbines, PV installations and wind turbines with a capacity of 2 to 5 kW and
has installed them in several developing countries. To be able to maintain and
expand these installations, there is quantitative feedback needed on top of the
already available qualitative feedback from the communities.
Summary
In the framework of this master thesis a data logger was designed for measuring
electric quantities (voltage, current, power factor, frequency, ...), ambient temperature
and relative humidity, during least one year and for storing these data on an SD card
in the form of CSV files. These data can then be read and analyzed in Excel or in the
Java program REA (Renewable Energy Analyzer) that was written for this master
thesis. The designed data logger is robust by working with standardized through-hole
components and is provided with sufficient protections. He can store parameters of
electric systems from 0 to 5.5 kW.
