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.
Upon completion of this module you will be able to:
- List the three main quantities measured by wind turbine sensors
- Name three types of displacement sensors
- Describe the operating principle of ultrasonic sensors
- Explain the difference between a cup and ultrasonic anemometer
- List four applications of temperature sensors in a nacelle
- Describe the difference between an NTC and PTC thermistor
- Compare a single-axis and three-axis vibration sensor
- Differentiate between pitch sensors and yaw sensors
- List the six steps associated with a condition monitoring system
- Explain the purpose of a communications bus
- Define PROFINET and the IEC 61400-25 standard
