Abstract

The invention realtes to an online service-life management system for the important parts of the host machine of plant-level multi-electric motor machine sets. The invention is characterized in that the system comprises a service-life calculation / application server and software, a database server, an external system interface, a plant-level supervisory information system SIS, a parameter measuring point, a web page server and a user-end browser. The online service-life management method is that the calculation analysis software for the host machine of the plant-level multi-electric motor machine sets, which is compiled by the C Language, is applied to the calculation / application server, carries through the online calculation of the transient life loss and the accumulative life loss of the importants parts of the host machine, directs the operational manipulation and the optimal operation of the electric motor machine sets, and recommends the optimal maintenance measures of the plant-level multi-electric motor machine sets. The management system has the advantages of realizing the online management for the important parts of the host machine of the plant-level multi-electric motor machine sets and achieving the technical effect that the service life of the important parts of the host machine of the multi-electric motor machine sets in a power plant are managed by a set of the service-life management system.

Description

technical field [0001] The invention relates to a method and system for on-line life management of important components of a main engine of multiple generator sets at the plant level and a system, which is applied to the equipment management of multiple generator sets at the plant level of a power plant, and belongs to the technical field of power generation engineering and generator sets. Background technique [0002] The important parts of the main engine of the generator set refer to the parts that are expensive to manufacture and have serious damage consequences, including rotating parts, pressure-bearing parts and winding insulation. The important rotating parts include the rotor of the steam turbine and the rotor of the generator; the important pressure-bearing parts include the cylinder and valve housing of the steam turbine, the steam drum of the boiler, the steam-water separator, the header, the pipe and the pipe; the important winding insulation includes the stator ...
