JI Guo-rui · Electric Power · 2006
A DSP-based fault diagnosis system on turbo-generator was designed.The system transforms the vibration signals into useful information via FFT and FWT,builds a database of fault symptoms,detects the fault symptoms or abnormal operation by getting the symptoms from the transformed information,and provides many assistant analyzing tools.The application in Tianjin Dagang Power Plant shows that the system can detect the fault symptoms effectively and analyze the faults with better social and economic benefits.
