| Abstract: | A fault diagnosis method of water turbine guide learing based on multi sensor data fusion is presented in this paper.Based on Dempster shafer evidence theory,fusion diagnosis for water turbine guide bearing is realized by several parameters which are gotten by the multi sensor system of comprehensive monitoring on the water turbine guide bearing.The validity of this method has been proved by an example. |
