DISTURBANCE OBSERVER BASED SPEED CONTROLLER FOR DUAL GENERATOR TYPE WIND TURBINE AND OPERATING METHOD THEREOF

摘要

A disturbance observer-based speed controller and its operating method of a parallel wind turbine according to the present invention is disclosed. The disturbance observer-based speed controller according to the present invention includes an electric system for outputting the applied torque of the first generator and the applied torque of the second generator based on the current control command value of the first generator and the current control command value of the second generator, A mechanical system for outputting a rotational speed of the first generator and a rotational speed of the second generator based on the input torque of the first generator and the applied torque of the second generator; And a disturbance observer for outputting the output values of the first generator and the second generator based on the rotation speeds of the first generator and the second generator and the current control command values of the first generator and the second generator, Wherein the current control command value of the first generator and the current control command value of the second generator are set such that the output value of the speed controller of the first generator, the output value of the speed controller of the second generator and the output value of the disturbance observer of the first generator, And the difference value between the output values of the output values.
