Problems solved by technology

For the collected power data of wind turbines, due to the influence of a series of factors such as man-made (such as maintenance, power cuts, etc.) and non-man-made (weather, air density, ambient temperature, etc.), the original The distribution of data points of power data is chaotic and disorderly, so it cannot be directly used for the drawing of fan power curve of wind turbine and the performance analysis of wind turbine unit

Embodiment Construction

[0045] In order to illustrate the present invention more clearly, the present invention will be further described below with reference to the embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0046] Each wind turbine has its own fan power curve, which needs to be drawn according to the collected power data of the wind turbine (power corresponding to different wind speeds). For the collected power data of wind turbines, due to the influence of a series of factors such as man-made (such as maintenance, power curtailment, etc.) and non-artificial (weather, air density, ambient temperature, etc.) The distribution of data points of power data is chaotic and disorderly, and cannot be directly used for drawing the fan power c...

Abstract

Embodiments of the present invention disclose a method, computer equipment and medium for processing power data of a wind turbine. In a specific embodiment, the method includes: acquiring wind turbine power data, and dividing the acquired wind turbine power data into a plurality of sections according to wind speed; The first marking of the digit method is to mark the abnormal power data with abnormally large power values ​​in each interval; the unmarked power data in each interval is subjected to the optimal variance method within the group based on the adaptive threshold setting. Marking for the second time is to mark abnormal power data with an abnormally small power value in each interval, and obtain normal power data composed of unmarked power data in each interval. This embodiment can accurately and efficiently implement data cleaning of the wind turbine power data.

Description

technical field [0001] The present invention relates to the technical field of data processing. More specifically, it relates to a method, computer equipment and medium for processing power data of a wind turbine. Background technique [0002] Each wind turbine has its own fan power curve (wind speed-fan power scatter diagram), which needs to be drawn according to the collected power data of the wind turbine (power corresponding to different wind speeds). For the collected power data of wind turbines, due to the influence of a series of factors such as man-made (such as maintenance, power curtailment, etc.) and non-artificial (weather, air density, ambient temperature, etc.) The distribution of data points of power data is chaotic and disorderly, and cannot be directly used for drawing the fan power curve of wind turbines and analyzing the performance of wind turbines. Therefore, it is necessary to perform abnormality detection or screening on the original power data of th...
