1. A method comprising: monitoring, by a turbine controller, technical parameters of a turbine; detecting a turbine misbehaviour including abnormal turbine behaviour below a fixed alarm limit based on the monitoring of the turbine; performing computerized root cause analysis based on the detected turbine misbehaviour to determine a root cause of the turbine misbehaviour, the root cause analysis comprising: forming a misbehaviour pattern predicting failure of the turbine with timeslots of normal operation of the turbine and timeslots of the detected turbine misbehaviour of the turbine wherein the misbehaviour pattern is based on a cluster of misbehaviour; comparing a timeslot of the misbehaviour pattern to corresponding timeslots for each information associated with a type of the turbine misbehaviour in at least one database relating to the turbine; calculating an indicator, for said each information, indicative of a fit of the misbehaviour pattern; ordering into a list the calculated indicator for said each information to prioritize a representation of a root cause of the turbine misbehaviour; and automatically identifying a best fit from the list; and taking preventive actions to prevent the failure associated with the root cause associated with the best fit.
