On-line fault diagnosis for steam turbine rotors is important tothe safe operation of power plants. As a result, a Windows-based on-line fault diagnosing system for steam turbine rotors (TRFDS) is developed using DELPHI language for programming. Its hardware includes sensors, vibration data acquisition card and computer equipment, and its software comprises functional modules of data acquisition, monitoring and analysis of vibration signals, fuzzy fault diagnosis, database management as well as other auxiliary software. TRFDS is characterized by easy operation, fast and accurate acquisition and analysis as well as better capabilities of fault diagnosis and forecast, etc. Model experiment results show that the system can meet the requirements of on-line monitoring and fault diagnosis on site.
