Embodiment Construction

[0041] The present invention will be further described below in conjunction with specific examples.

[0042] The method for increasing the power generation of wind power generators described in this embodiment, the specific flow chart is as follows image 3 shown, including the following steps,

[0043] 1) After the nacelle wind vane is initially zeroed, second-level data of the fan is collected through the wind farm SCADA system or the centralized control system of the big data platform. The data label points include wind speed, wind direction, north wind direction, air density, active power of the grid, and unit operation mode and power limit category.

[0044] 2) Divide the continuous second-level data into multiple continuous and equal-time split samples, each split sample takes 10 minutes, and standardize the wind speed for each split sample, that is, transform the wind speed under the actual air density into the contract The wind speed of the air density screens out th...

Abstract

The invention discloses a method for increasing the power generation of a wind power generating set. Through data analysis, the windward deviation interval in which the optimal power curve of the generating set is located is obtained, and the middle value of the interval is selected as the recalibration angle of the wind vane in the nacelle on the basis of the initial zero calibration. , so as to re-calibrate the wind vane in the nacelle, thereby optimizing the power curve of the unit, and then increasing the power generation of a single unit or even the entire unit, and increasing the direct economic benefits of the wind farm.

Description

technical field [0001] The invention relates to the technical field of large-scale semi-direct drive wind turbines, in particular to a method for increasing the power generation of a wind power generating set. Background technique [0002] The power curve is used to describe the relationship between the power output of the wind turbine generator set and the wind speed. The better the power curve, the better the performance of the unit and the more power it generates. [0003] There are many factors that affect the power curve of the unit, and one of the very important factors is the influence of the deviation between the incoming wind direction and the nose orientation (wind deviation). Such as figure 1 Shown is a schematic diagram of the change of wind energy loss with windward deviation. Theoretically, when the windward deviation is 0°, the unit power curve is optimal, and the greater the deviation, the worse the unit power curve. [0004] At present, there are some def...
