Abstract

The invention relates to a device for online monitoring and controlling low cycle fatigue life consumption of components of a steam turbine and a method, belonging to the technical field of the steam turbine. The invention is characterized in that the device consists of a compute server, a database server, a web server, a user browser and a plant supervisory information device; the web server is connected with the user browser, the database server and the compute server respectively; the compute server is connected with the database server which is connected with a digital electric-hydraulic control device of the steam turbine by the plant supervisory information device. The invention has the advantages of being capable of realizing online computing and controlling of transient low cycle fatigue life consumption of a plurality of components of the steam turbine.

Description

technical field [0001] The invention relates to an on-line monitoring and control device and method for low-cycle fatigue life loss of steam turbine components, belonging to the technical field of steam turbines. Background technique [0002] The 16 parts of the steam turbine are high-pressure rotor, medium-pressure rotor, low-pressure rotor, high-pressure inner cylinder, medium-pressure inner cylinder, low-pressure inner cylinder, high-pressure outer cylinder, medium-pressure outer cylinder, low-pressure outer cylinder, high-pressure nozzle chamber, and high-pressure main steam valve Housing, medium pressure main steam valve housing, high pressure regulating valve housing, medium pressure regulating valve housing, high pressure steam pipeline, medium pressure steam pipeline, etc., are characterized by large size and high cost. During the start-up, shutdown and load changes of the steam turbine, due to the uneven temperature distribution along the radial direction of the com...
