Abstract
Based on the existing situation of large hidden trouble in axial displacement protection of steam turbine in a certain factory
by optimizing the hardware configuration of the steam turbine safety monitoring system and the logic of ETS devices
the axial displacement protection of steam turbine can meet the requirements of "twenty-five countermeasures". It is very important for the safe and stable operation of steam turbine to avoid misoperation and refusal of main protection of steam turbine.
