Problems solved by technology

[0002] In order to achieve high wind energy efficiency and power control during the operation of the wind turbine, the current control methods basically use pitch technology and yaw technology. This method is effective for the control of horizontal axis models, but it is used for vertical axis models. , Especially for large-scale ones, there are not small problems in these technologies: first, the blades of the vertical axis fan run at a linear speed on the circumference of the wind rotor, and the precessive torque when adjusting the pitch angle to ro

Abstract

The invention discloses a control method of a wind collecting-type vertical-shaft fan and a wind generating set thereof. The method is characterized in that the inflow wind speed, the relative wind speed, the attack angle of blades and the driving force of wind wheels are controlled by adjusting the position angle of a wind collecting system of the wind collecting-type vertical-shaft fan, thus being capable of controlling wind energy efficiency and fan power; a wind collecting-type vertical-shaft wind-driven generator mainly consists of a main shaft, a wind wheel, a tower post, bearings, a pedestal, a gear box, a generator and the wind collecting system, wherein the wind collecting system mainly consists of a wind guiding wing, a wind collecting wing and a driving and controlling component; and the purpose of controlling the wind energy efficiency and the fan power is achieved by adjusting and controlling azimuth angels of the wind guiding wing and the wind collecting wing.

Description

technical field [0001] The invention belongs to the design and manufacture technology of a wind power generating set, in particular to a control method of a wind-collecting vertical shaft (also called a vertical axis) fan and the wind power generating set. Background technique [0002] In order to achieve high wind energy efficiency and power control during the operation of the wind turbine, the current control methods basically use pitch technology and yaw technology. This method is effective for the control of horizontal axis models, but it is used for vertical axis models. , Especially for large-scale ones, there are not small problems in these technologies: first, the blades of the vertical axis fan run at a linear speed on the circumference of the wind rotor, and the precessive torque when adjusting the pitch angle to rotate the blades will easily cause the blades to vibrate and cause structural fatigue. The safety and service life of the fan are reduced; the second is ...
