Embodiment Construction

[0064] The traditional method of facing the wind usually judges whether it needs to yaw against the wind according to the given allowable deviation threshold against the wind and the set waiting time. Because this method only uses a single wind direction condition as the main judgment basis, when the collected wind direction fluctuates greatly and the frequency of wind direction changes is high, using this method for yaw control often causes lag in response to wind, Problems with jogging yaw, inaccurate yaw counts, or twisted cables.

[0065] In order to solve the problems and defects existing in the prior art, the inventor of the present invention provides a method for controlling the wind yaw of a wind power generating set based on the long-term valuable experience of front-line work in wind power plants, including:

[0066] Collect the original wind direction value and convert it into the corresponding angle to be yaw;

[0067] Judging whether the angle to be yaw is greate...

Abstract

The invention provides a method for controlling the wind yaw of a wind power generating set, comprising: collecting the original wind direction value and converting it into a corresponding angle to be yaw; judging whether the angle to be yaw is greater than a preset allowable deviation angle , if so, obtain the windward delay time that needs to be waited at the current wind speed; when the windward delay time arrives, judge whether the preset starting windward condition is met, and if so, yaw according to the angle to be yawed. The method for controlling the wind yaw of the wind power generating set provided by the present invention introduces the theoretical power deviation and the operating deviation based on the ambient temperature to determine the time of the wind to solve the problem of the delay of the automatic response to the wind, and solves the problem of simply using the average wind direction to determine the time of the wind To the wind lag problem.

Description

technical field [0001] The present invention relates to the technical field of wind power generation. Specifically, the present invention relates to a method, device and equipment for controlling wind yaw of a wind power generating set. Background technique [0002] Energy is the main material basis of social economy and human life, and the driving force of social development. However, the reserves of non-renewable energy such as petroleum, coal, and natural gas, which are the main pillars of world energy, are decreasing day by day. Many countries in the world are developing wind power generation. As a new energy source, wind power generation has formed a relatively mature scale. [0003] The yaw system is one of the important components of the wind turbine. Its main function is to keep the wind turbine in the windward direction within the available wind speed range, and strive to capture wind energy to the maximum extent. However, the actual working yaw-facing position of ...
