基于灰色FTA的风机叶片覆冰对机组运行可靠性影响研究
Research on the influence of fan blade icing on the operation reliability of unit based on grey FTA
摘要
Abstract
The grey FTA model of wind turbine is put forward according to the influence of blade icing on the operation reliability of wind turbine. Based on the statistical analysis of wind farm operation data of a company in Xinjiang,through the establishment of grey matrix set,to deal with the blade icing of wind turbine fault data; Grey relational degree of ice cover and other common faults is calculated. Grey FTA analysis is carried out, and the FTA fault diagram is drawn. It is concluded that the fault correlation between blade icing and pitch changing inverter, loss of ok signal and excessive acceleration of engine room is the key points that need to be investigated when icing occurs. This research means great significance to reduce the operation and maintenance costs of wind turbines,which further improve the efficiency of operation and maintenance.关键词
