Abstract

The embodiment of the invention discloses a fan yaw correction method and device, a computer device and a readable storage medium, and relates to the technical field of wind power generation. The fanyaw correction method and device, the computer device and the readable storage medium are used for solving the problem of lacking an anticipation mechanism for the error conditions of the yaw angle inthe prior art. The fan yaw correction method includes the steps that the left yaw duration within a target time interval and the right yaw duration within the target time interval are obtained; a yawangle error parameter is calculated according to the left yaw duration and the right yaw duration; and when the yaw angle error parameter exceeds a preset value, an early warning is started to notifystaff that a yaw angle error is large.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind turbine yaw correction method and device, a computer device and a readable storage medium. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy. In a wind turbine, the yaw system is one of the important components of the wind turbine. It is used to cooperate with the control system of the wind turbine so that the wind turbine is always in the wind State, make full use of wind energy. [0003] The calculation of the yaw angle is a very important part in the yaw system. The high-precision yaw angle calculation is not only beneficial to the yaw control, but also can be used to reduce the failure rate of the yaw safety chain. For example, an accurate yaw angle is conducive to accurate calculation of the twisted cable angle. If the calculation error of the yaw angle is large, it will easily lead to a large calc...
