Abstract—Unpredictable failures of wind turbines and the
associated costs; have contributed to the development of
condition monitoring systems. The availability of ultra-low
power devices has contributed in creating autonomous systems
that operates on energy harvested from the surrounding
environment. This research aims to develop a design of a
self-sufficient condition monitoring system, that is able to run on
renewable energy. Energy is harvested from an electromagnetic
energy harvester that harnesses the rotational motion of the
wind turbine blades and converts it to useful power. After
conditioning and storing the harvested energy, the maximum
available power is 435 mW. The energy harvested is used to
charge a lithium ion battery for backup as well as power the
condition monitoring system. The system is validated by both
simulation models and experimental measurements on a wind
turbine prototype model.
