Problems solved by technology

[0010] However, since the conventional Savonius drag type vertical axis wind turbine has a large efficiency fluctuation according to the rotational speed ratio of the wing tips, it is necessary to increase the incoming wind speed by installing inlet guide vanes and properly adjust the wind speed to the impeller according to the measured wind speed Control the number of revolutions of the impeller

Abstract

Provided are an apparatus and method for controlling a vertical axis wind power generation system that controls the rotation of guide vanes according to wind direction and speed, appropriately controls a direction of wind passing over an impeller, thereby maintaining a rotational speed generating the maximum power, maintains output power of a generator as rated power according to wind direction and speed, and stops the generator when a low or high wind speed outside a setting value range, an error in a structure, a fault in a braking unit, and / or a fault in guide vanes is detected.

Description

[0001] Cross References to Related Patent Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2007-0062798 filed in the Korean Intellectual Property Office on Jun. 26, 2007, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to an apparatus and method for controlling a vertical axis wind power generation system, and more particularly, the present invention relates to an apparatus and method for controlling a vertical axis wind power generation system comprising The rotation of the vanes in the VAWG turbine guides and properly regulates the direction of the wind entering the VAWG system to pass over the rotor blades to maintain the rotational speed and generate maximum power. Background technique [0004] Generally, wind power generation systems are classified into two types based on an axis around which a turbine rotates, ie, a horizontal axis wind turbi...
