System and process status management of a wind turbine

A system (100) of wind turbine comprising at least one wind turbine (202) and including a controller (204) adapted to manage the duration of operational life of the at least one wind turbine (202), said controller being coupled communicatively wind turbine and a server subsystem (216) and said controller (204) configured to: receive operational data (214) of the wind turbine; transmit operational data to the server subsystem; transmit to the server subsystem (216) a request for historical data (222) corresponding to the wind turbine (100); receiving a response from the server subsystem (216), comprising the response to historical data from the wind turbine; and characterized in that the controller (204) is further configured to: determine an estimate of a time to failure of the wind turbine, according to at least one of operational data and historical data, determining the estimated time to failure from a combination of two or more failure probabilities using equations melting data based on a theory of evidence of Dempster-Shafer, fusion Bayesian data, and / or fuzzy logic, in which the failure probabilities comprise a first failure probability based on at least one maintenance factor based on physics, a second failure probability based on at least one empirical factor maintenance and a third failure probability based on at least one factor based maintenance events.
