    摘要: A turbine performance diagnostic system creates a performance report for one or more turbines and includes an assessment module that receives operating data from at least one turbine and produces a performance report from the operating data. The assessment module includes a change detection module configured to determine when at least one parameter has changed beyond an associated threshold and generate an alarm and a root cause analyzer coupled to the change detection module that predicts a root cause of the alarm utilizing a Bayesian Belief Network (BBN). The performance report includes an indication of the predicted root cause.

    摘要: A method for monitoring the condition of oil contained within a gearbox of a wind turbine is disclosed. The method generally includes receiving a signal corresponding to a measurement of an oil parameter of the gearbox, comparing the measurement to a predetermined limit for the oil parameter, assigning a severity level based on the comparison of the measurement to the predetermined limit and determining a recommended course of action for the wind turbine based on the severity level.

    摘要: A system for selecting a representative sensor set of a power plant is provided including a computer. The computer has a memory. The memory stores a list of all feasible sensor sets, and at least one variable that is used to calculate a local minimum value of a cost function and a cost function value. The computer includes control logic for executing an algorithm. The computer includes control logic for selecting a proposed sensor set from the list of all feasible sensor sets. The proposed sensor set is based on a specific iteration of the algorithm. The control module includes control logic for determining if the system is observable using the proposed sensor set. The control module includes control logic for determining if the cost function value is less than the local minimum value of the cost function, if the system is observable using the proposed sensor set.
