Abstract

The invention discloses a health status online monitoring device of a wind generating set and a monitoring method of the monitoring device, wherein the monitoring device comprises a signal acquisition module, a signal preprocessing module, a data fusion module and a health status information output module. Firstly, acquiring signals of each component of the wind generating set, performing preprocessing to the acquired signals, performing data fusion processing to relevant data and extracting data foretaste information; under the action of an inference engine, matching the data information with the data information in an expert database, making a health status diagnosis decision and offering to users; taking relevant actions according to alarm messages or health status diagnosis decision information; The health status online monitoring device adopts multiple sensors to acquire the health status information of the wind generating set and can judge a component which is possible to have a fault in advance by threshold value control and data fusion and ensure the reliability and the accuracy of the health status diagnosis decision of the wind generating set.

Description

technical field [0001] The invention relates to a monitoring device, in particular to an online monitoring device for the health state of a wind power generating set, belonging to the technical field of wind power generation. The invention also relates to a method for online monitoring of the health state of the wind power generating set. Background technique [0002] According to the draft of the national "New Energy Industry Revitalization Plan", the total installed capacity of wind power in my country will reach 150 million kilowatts in 2020, which is five times the goal of the "Renewable Energy Medium and Long-Term Development Plan" released in 2007. According to the plan, my country will build eight 10 million-kilowatt wind power bases in seven provinces including Gansu, Xinjiang, Hebei, Jilin, Inner Mongolia, Jiangsu and Shandong. Gansu Jiuquan 10 million-kilowatt wind power base construction plan has a total installed capacity of 35.65 million kilowatts; Xinjiang Ham...
