CMS - CONDITION MONITORING SYSTEM

CMS - CONDITION MONITORING SYSTEM


Eólica Tecnologia has a Vibration-based Condition Monitoring System (CMS) on all wind turbines. The targets of the system are reduction of maintenance costs, increase of availability, avoidance of unplanned downtimes, improvement of quality & reliability and extend wind turbine’s lifetime.


Wind farms are unlike conventional power stations, the turbines are exposed to harsh weather conditions, including severe winds, high temperature, lightning and thunderstorms. Due to these external operational conditions, the wind turbines suffer constantly intense mechanical stress with a highly variable operation conditions (speed, load, etc.). Therefore, a high degree of maintenance is required to provide a safe, cost-effective and reliable power output.


Futhermore, Eólica Tecnologia has developed its own online system to treat and analyze automatically a large database from specific vibration data for all main components of the wind turbine. It works in three main steps: data acquisition using 8 sensors per turbine, signal processing/analysis with various techniques, and daily tracking/diagnosis. The system is also capable of generating reports and alarms identifying the fault and its location, maximizing reliability of Eólica Tecnologia’s wind farms.
