Windturbine Monitoring System

The monitoring of lubricant needs oil temperature sensor, particle counter sensor and oil level sensor to work together in gathering the temperature, quality and liquid level information of the lubricant so that unwanted conditions in gear box and turbine such as lubricant shortage, low-quality and overheated lubricant could be diagnosed before any damage. Voltage and current sensors are used to monitor generator’s output power as an output power higher than a certain threshold tends to damage the generator. Temperature and humidity sensors installed in the nacelle are used to monitor environmental conditions so as to protect parts from being damaged by inappropriate temperature and humidity. In addition to various sensors, a wind turbine monitoring system has a signal processing unit and a communication interface. Signal processing unit is mostly a high-performance microprocessor or DSP, responsible for analyzing and processing data that is collected by sensors. This is then transmitted through a wireless network (e.g. Zigbee®) for data logging and telemetric purposes.
