Abstract:
1. A monitoring and processing equipment (SMP) for a wind turbine (Ai), the wind turbine including a control system (PLC), said equipment comprising: connection means with said control system (PLC) of the wind turbine, and connection means with a group of accelerometers (Si) placed in pre-established components (Ei, Mi and Gi) of the wind turbine, said monitoring and processing equipment being configured to begin a capture of the signals of the group of accelerometers as long as predetermined operation variables of the wind turbine, received from the control system, are within a predetermined operation range, and said monitoring and processing equipment being configured to complete said signal capture as long as the value of said operation variables does not vary, during the entire signal capture, beyond upper and lower limits configured in the equipment, and said monitoring and processing equipment comprising: processing means for processing the captured signals of the accelerometers to obtain a set of overall variables associated to the captured signals, and means for generating alarms related to failures or malfunctionings of mechanical components of the wind turbine.
