STEAM TURBINE SHELL DEFLECTION FAULT-TOLERANT CONTROL SYSTEM, COMPUTER PROGRAM PRODUCT AND RELATED METHODS

摘要

Various approaches include: obtaining temperature data indicating temperatures of distinct zones in an upper half of a steam turbine shell and a lower half of a steam turbine shell; determining whether a difference between a temperature of a zone in the upper half of the steam turbine shell and a temperature of a neighboring zone in the lower half of the steam turbine shell exceeds a threshold; and initiating a change in a state of a thermal element in at least one of an adjacent zone to at least one of the zone in the upper half of the steam turbine shell or the neighboring zone in the lower half of the steam turbine shell in response to determining the difference exceeds the threshold.

1. A system comprising:
at least one computing device configured to control a state of a thermal element in contact with a steam turbine shell having an upper half and a lower half, by performing actions including:
obtaining temperature data indicating temperatures of distinct zones in the upper half of the steam turbine shell and the lower half of the steam turbine shell, the thermal element having corresponding distinct zones as the upper half of the steam turbine shell and the lower half of the steam turbine shell;determining whether a difference between a temperature of a zone in the upper half of the steam turbine shell and a temperature of a neighboring zone in the lower half of the steam turbine shell exceeds a threshold; andinitiating a change in the state of the thermal element in at least one of an adjacent zone to at least one of the zone in the upper half of the steam turbine shell or the neighboring zone in the lower half of the steam turbine shell in response to determining the difference exceeds the threshold.
