Multi-class controller for wind power generator and wind power generation system using same

A multi-class controller that controls a wind power generator and a power transmission unit that supplies power generated by the wind power generator to a predetermined target, the multi-class controller comprising:

• a sensor unit configured to sense environmental conditions of an area where the wind power generator or the power transmission unit, which is a control target, is installed and a state of components constituting the control target, and generate a sensing value;
• and
• a control unit configured to receive the sensing value to determine an operation state of the control target, convert a predetermined control default value for controlling the control target to a control value by applying a predetermined adjustment value according to the operation state, adjust the control value so as to maximize an amount of power generation or reduce a load applied to the component aged over a reference value by determining aging of the component, and search for an adjustment value for generating the control value;
• and
• wherein the control unit includes:
• a main control unit configured to receive the sensing value and output the control value to the control target;
• and
• a self-optimizing unit configured to receive the sensing value from the main control unit to calculate the adjustment value, or request a test for determining the adjustment value to the main control unit, and
• wherein the self-optimizing unit determines the adjustment value by calculating the adjustment value while randomly setting a size or direction of an adjustment deviation of the adjustment value, collecting results obtained by using the control value to which the calculated adjustment value is applied, and comparing the results.
