Identification method, device and equipment for extreme turbulent flow and computer readable storage medium

Abstract

The embodiment of the invention discloses an identification method, device and equipment for extreme turbulent flow and a computer readable storage medium. The identification method comprises the steps that in the current detection period, rotation speed values of a wind generating set are acquired according to a preset sampling period; the number of the rotation speed values larger than a set rotation speed value in the rotation speed values acquired in the current detection period is recorded; and if the number of the rotation speed values recorded in the current detection period is larger than a set value, it is judged that the wind generating set is in an extreme turbulent flow working condition. According to the embodiment of the identification method, device and equipment for the extreme turbulent flow and the computer readable storage medium, the identification efficiency and accuracy of the extreme turbulent flow working condition can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of wind power generating sets, in particular to an identification method, device, equipment and computer-readable storage medium of extreme turbulence. Background technique [0002] In order to ensure the safety and long-term stable and reliable operation of wind turbines, the design of wind turbines needs to consider the influence of operating environmental conditions and power environment. These influences are mainly reflected in several aspects such as load, service life and normal operation. Various environmental conditions are divided into normal external conditions and extreme external conditions (such as turbulent flow conditions, etc.), where normal external conditions involve long-term fatigue loads and operating conditions. Extreme external conditions occur rarely, but are potentially critical external design conditions. The load design of wind turbines needs to consider these external con...

[0004] At present, the turbulence intensity is usually estimated by using the anemometer to measure the wind speed. However, due to the error in the measurement of the anemometer itself, and the measurement of the wind speed signal also has various interferences, the evaluation results of the turbulence intensity based on the wind speed measured by the anemometer poor accuracy
