Management of Mechanical Vibration and Temperature in Small Wind Turbines Using Zigbee Wireless Network
Abstract
This paper presents the development of a
methodology to manage the mechanic vibration and temperature
from Small Wind Turbine (SWT). The objective with this research
is propose a new diagnostic and protection tool through analysis
and monitoring signals of vibration and temperature from wind
turbines, aiming predict a need of preventive maintenance and
mostly avoids catastrophic failures. For this feature the system will
be composed of a Triple Axis accelerometer who will identify
vibration, thermocouples to identify the temperatures at critical
points of wind turbine, a microcontroller hardware which will
make acquisition and processing of signals from sensors and finally
a wireless transmission system using technology ZigBee. The post
processing is performed remotely through a computer that receives
the data submitted via wireless network presenting them to the
user via graphical interface. The software of User friendly interface
will have the functionality plus online display of received data also
the possibility of storing and reporting data rates of vibration and
temperature obtained during monitoring. Finally featuring the
prototype of the hardware and software as well as some results
obtained in experimental scale.
