System and method for detecting turbine underperformance and operation anomaly

A non-transitory computer-readable medium having stored thereon instructions which when executed by a control processor cause the control processor to perform a method of correcting turbine underperformance, the method comprising:

• accessing monitored operational data for the turbine;
• calculating a power production curve using at least a portion of the monitored operational data;
• predicting a baseline power production curve based on expected performance of the turbine;
• detecting a first set of changes between at least the portion of the monitored operational data and the baseline power production curve;
• generating one or more monitored operability curves from the at least a portion of the monitored operational data, each of the one or more monitored operability curves describing a relationship between monitored values for paired operational variables;
• generating one or more baseline operability curves for the turbine, each of the one or more baseline operability curves describing an expected relationship between the paired operational variables;
• detecting a set of changes between the one or more monitored operability curves and a corresponding one of the one or more baseline operability curves;
• comparing one or more of the set of changes to a respective predetermined metric for each of the paired operational variables;
• and
• based on a determination that one or more members of the set of changes is in excess of the respective predetermined metric, providing feedback to the turbine control system identifying at least one of the paired operational variables that corresponds to the member of the set of changes in excess of the predetermined metric.

A turbine control system for correcting turbine underperformance, the system comprising:

• a turbine having a control processor in communication with a memory unit and a data store;
• the control processor including a processing unit, the control processor in communication with one or more turbine actuators;
