Method and device for condition monitoring of wind power generating set

Abstract

An embodiment of the present invention provides a method and device for monitoring the state of a wind power generating set, wherein the method includes: acquiring vibration data of a target component on the wind generating set, and the operation data of the wind generating set at a corresponding time, and storing the The above vibration data and the operation data are stored in the database; according to the operation data and the vibration data, the operation state of the wind power generating set is analyzed, and the analysis results are stored in the database; Whether the network occupancy rate of the communication network between is lower than the preset threshold; if so, the vibration data, the operation data, and the analysis results are sent from the database to the host computer, so that all The upper computer determines the operating state of the wind power generating set according to the vibration data, the operating data, and the analysis results. The embodiments of the present invention can analyze continuous vibration data in real time and reduce the load on the upper computer.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wind power generation, and in particular to a method and device for monitoring the state of a wind power generating set. 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 condition monitoring device of wind turbines can detect problems early during the operation of wind turbines. According to the relevant information, the maintenance personnel can carry out targeted maintenance on the wind turbines in advance to improve the operating life of the wind turbines. [0003] The condition monitoring device mainly monitors the vibration amplitude and frequency characteristics of the main bearings, generators and gearboxes in the wind turbine, and according to the current wor...

Problems solved by technology

The independent status online monitoring device is a set of independent devices, including sensors, data acquisition and data analysis. Its disadvantage is that it can only exchange information with a small amount of data with the wind turbine, which is not convenient for large data volume. Real-time online analysis

The integrated state online monitoring device is directly integrated into the control device of the wind turbine. The controller that controls the operation of the wind turbine collects and analyzes the vibration data of large components. interfere with the normal operation of
