Monitoring & Communication

This module introduces the student to monitoring devices such as displacement sensors, temperature sensors and vibration sensors. The applications of temperature sensors, such as thermistors, used in wind turbines are presented. The main types of displacement sensors are discussed, and the most common anemometers are described.  In addition, it is in this module that the student learns the purpose of a communications bus, and the principles of condition monitoring systems. The main communication protocols in wind turbines and wind farms are also described including the IEC 61400-25 standard
