State monitoring method and device for wind power generator set

Abstract

The embodiment of the invention provides a state monitoring method and device for a wind power generator set. The method comprises the following steps of acquiring vibration data of a target part on the wind power generating set and running data of the wind power generating set at the corresponding moment, storing the vibration data and the running data in a database; analyzing the running state of the wind power generating set according to the running data and the vibration data, and storing the analysis result in the database; determining whether the network occupancy rate of the communication network with the upper computer is lower than a preset threshold value or not; and if yes, sending the vibration data, the running data and the analysis result to the upper computer from the database, so that the upper computer can determine the running state of the wind power generating set according to the vibration data, the running data and the analysis result. According to the embodiment of the invention, continuous vibration data can be analyzed in real time, and the load of an upper computer is reduced.

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
