Steam-induced vibration fault seriously affects the reliable operation of supercritical steam turbine. A lot of actual cases of steam-induced vibration of steam turbine were collected in this work. Based on the cases, steam-induced vibration fault was statistical and classified by fault severity, fault reason, occurrence load and happened time. The results show that steam-induced vibration usually occurs after turbine runs one year later and turbine is with a high load. Oil temperature change is the main running parameters which affect steam-induced vibration. Distribute steam mechanism, especially improper opening and order of adjustment valve, is the most important factor causing steam-induced vibration fault. Meanwhile, based on the FMEA method, fault mode of steam-induced vibration was analyzed in detail.

Failure Modes and Effects Analysis (FMEA) method has been used to study the reliability of many different power generation systems, making it easier to take actions to overcome such issues, thus enhancing the reliability through design. A FMEA Knowledge Base System was designed and realized in this paper, and this system was used to design new steam butterfly valve for steam turbine. Through the system designer will improve product quality, and reduce risk.
