Abstract

Abstract: In startup procedure of one power plant unit, steam control valve was failure to open. By overall inspection, it was found that the secondary pulse oilpressure was lower than normal. The initial judgment for it may be oil leakage, after inspecting and treating the fault was eliminated. The treatment method may serve as reference for other power plants to search the same type fault.

Key words: gas turbine unit, start-up, failure to open, fault reason, analysis, fault treatment
