SUMMARY:

In wind systems, the rotational speed is controlled through the blade angle system, aiming at better use of the kinetic energy of the wind. In this work, the rotor blade angle system is electric, regulated by motors that are mounted on various gear stages. Supervised with standard monitoring, these engines suffer anomalies and defects that directly influence the productive operation of the wind turbine; They also involve intermittent unscheduled and large shutdowns of the wind turbine.
The rotor blade angle system is regulated by motors, and this system is composed of 03 distinct subsystems: control, power and protection. This set is managed by the master software of the wind turbine, from which it is possible to feed a database that stores information such as: temperature, voltage, electric current, torque, failure time, operating time, digital command, control and protection data. These data will be processed through mathematical models, so that it is possible to predict the time of failure of the equipment and, consequently, mitigate its premature and unforeseen failure, the number of unscheduled corrective interventions and the time of operational downtime of the wind turbine. It will be another tool to assist in increasing the reliability of the equipment, in the production of electricity and in the operational availability time.
