Abstract

The invention relates to a drift control method of wind mill based on wind vane and output power. When the absolute wind change value is higher than 15degree, the invention uses wind vane control method, and when the absolute wind change value is not higher than 15degree, the invention uses power control method. Since the wind direction and speed changes will change the output power of generator, the power checker can check the output power of motor, the invention only processes drift control when the wind direction changes, while the wind change is used as interference signal on the power control method. The power control method is divided into anti-clockwise rotation, clockwise rotation, and original position stop conditions. The invention can shorten the align time, improve accuracy and energy utilization.

Description

Technical field

[0001] The invention relates to a control method in the technical field of wind power generation, in particular to a wind turbine yaw control method based on a wind vane and output power. Background technique

[0002] Wind energy is a kind of renewable energy. In recent years, the development and utilization of wind energy has received extensive attention. But wind is a kind of vector and has randomness. Whether it is wind direction or wind speed, it is always changing. It is required to control the yaw control system of the wind turbine to ensure that the wind turbine nacelle is always facing the wind and improve the efficiency of wind energy utilization and wind turbines. life.

[0003] In the prior art, some people propose to adopt a passive upwind yaw system, which is controlled by the tail rudder of a wind turbine, and adopts a passive counterwind mode when the wind direction changes. It is mostly used for small, independent, non-grid-connected wind turbines....
