Abstract

The embodiment of the specification discloses a steam turbine bearing temperature protection method, device, electronic equipment and computer storage medium. The method includes the following steps: a) during the operation of the steam turbine, detecting the temperature of the corresponding temperature measuring point on each bearing bush of the steam turbine bearing; b) judging whether the temperature of the temperature measuring point exceeds the temperature of the steam turbine bearing The action threshold corresponding to the protection action; c) judging whether the temperature measuring point is a bad point, or judging whether the temperature rise rate corresponding to the temperature measuring point exceeds a predetermined threshold; d) according to the judgment result of step b and / or step c, It is determined whether to execute the temperature protection action of the steam turbine bearing. The embodiments of this specification can reduce unit malfunction and ensure safe, stable and economical operation of the unit.

Description

technical field [0001] This specification relates to the field of safe operation of thermal power units, and in particular to a steam turbine bearing temperature protection method, device, electronic equipment and computer-readable storage medium. Background technique [0002] In order to ensure the safe operation of large-capacity thermal power units, the requirements for the protection and control system of the units are getting higher and higher. At present, due to the limitation of the process, usually only single-point temperature measurement can be used for steam turbine bearing temperature protection, and the current measurement temperature of any one of the multiple temperature measurement points included in the steam turbine bearing can reach the temperature of the steam turbine bearing. When the action threshold corresponding to the protection action is set, the entire steam turbine bearing will be shut down. However, if the temperature of the temperature measurin...
