Control method, device and equipment for wind yaw of wind turbine generator system

Abstract

The invention provides a control method, device and equipment for wind yaw of a wind turbine generator system. The control method comprises the steps of collecting an original wind direction value and converting the original wind direction value into the corresponding to-be-yawed angle; judging whether the to-be-yawed angle is larger than a preset allowable deviation angle or not, and acquiring the wind delay time to be waited at the current wind speed if yes; and judging preset starting wind conditions are met or not after the wind delay time reaches, and yawing according to the to-be-yawed angle if yes. According to the control method for wind yaw of the wind turbine generator system, the time for wind is judged according to theoretical power deviation introduced for the lag problem of automatic response to the wind, and the operating deviation based on environment temperature; and the wind lag problem caused by determination of the wind time by singly using the average wind direction is solved.

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 for social development. However, the reserves of non-renewable energy such as oil, coal, and natural gas, which are the main pillars of the world's energy, are declining. 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 positive wind direction within the available wind speed range, and strive to capture the wind energy to the maximum. However, the actual yaw-to-wind position of the wind turbine cannot...
