MONITORING AND DATA PROCESSING EQUIPMENT FOR WIND TURBINES AND PREDICTIVE MAINTENANCE SYSTEM FOR WIND POWER STATIONS

摘要

A predictive maintenance system for wind parks, the wind park comprising a group of wind turbines (Ai), a communication network (RS) and a supervision and control system (ST). The predictive maintenance system comprises a monitoring and processing equipment (SMP) connected to the control system (PLC) of the wind turbine (Ai). The SMP gathers data from a group of accelerometers mounted in the wind turbine and sends alarm signals through the PLC to the supervision and control system. The predictive maintenance system of the invention is based on vibration analysis. The invention also refers to a monitoring and processing equipment (SMP) for wind turbines.
