Analysis on fast close problem of governing valve of Siemens steam turbine

Abstract

Abstract: Abstract:Aiming at the sudden tripping accident of the steam turbine unit during operation, it was pointed out that the fast close of the governing valve of the turbine caused a series of responses, and which caused the tripping accident of the unit. The reasons of the fast close of the governing valve and the rationality of the load rejection judging circuit were analyzed, and the concrete measures to solve the problems were proposed.

Key words: Keywords:steam turbine, tripping accident, fast close of governing valve, load rejection, analysis
