Abstract

Embodiments of the present invention provide a wind turbine data processing method and system, a wind turbine controller, and a wind farm group controller. The wind turbine data processing method includes: acquiring and buffering the operation data and vibration data of the wind power generating set; determining the preset target The cached operating data and vibration data of the storage set are data to be stored, and the data to be stored is stored; the cached operating data and vibration data that do not belong to the target storage set are determined to be invalid data, and the invalid data is cleared. Therefore, in the embodiment of the present invention, only the data to be stored needs to be stored, and invalid data is eliminated to reduce the storage load, thereby effectively reducing the transmission and analysis pressure of the wind turbine data processing system.

Description

technical field [0001] The invention relates to the technical field of wind power generating set equipment, in particular to a wind turbine data processing method and system, a wind turbine controller, and a wind farm group controller. Background technique [0002] The continuous innovation of technology has resulted in the continuous improvement of the single-unit capacity and installed capacity of wind turbines. The post-maintenance market of wind power generation is particularly important. The data processing system of wind turbines can detect problems early during the operation of wind turbines. According to the relevant information, the operation and maintenance personnel It is possible to carry out targeted maintenance on the fan in advance to improve the operating life of the unit. [0003] The wind turbine data processing system mainly detects the vibration amplitude and frequency characteristics of large components such as the main bearing of the wind turbine and th...
