Classification method and system for auxiliary devices of thermal power plant

Abstract

The invention provides a classification method and system for auxiliary devices of a thermal power plant and relates to the technical field of the power plant. The system comprises a data obtaining device which is used for obtaining system data of the thermal power plant; a data statistic device which is used for carrying out statics on the devices of the thermal power plant, the functions of the devices, influences on a production process and influences on production cleaning performance according to the system data; a device division device which is used for dividing the devices according to functions and classes, thereby obtaining various classes of devices; a parameter obtaining device which is used for obtaining classification parameters of the devices, wherein the classification parameters are preset set according to the functions, the influences on the production process and the influences on the production cleaning performance; and a device classification device which is used for classifying the various classes of devices according to the classification parameters. According to the method and the system, the auxiliary devices are classified, and demands of DL / T 793-2012 are expanded, thereby forming a more complete technical system and enabling an application range to be relatively wide.

Description

technical field [0001] The present invention relates to the technical field of power plants, in particular to the equipment classification technology of thermal power plants, and specifically to a classification method and system for auxiliary equipment of thermal power plants. Background technique [0002] At present, the reliability evaluation of thermal power plants refers to the evaluation of the reliability level of the unit, main engine, and auxiliary equipment. Since the reliability of the unit is mainly maintained by the maintenance work of the power plant, the main purpose of the reliability evaluation is to find ways to improve the reliability, so the reliability evaluation technology research can be further linked to the reliability and maintenance of the production unit Evaluation of management technology level, or production unit reliability technology system. [0003] In the existing technology, the evaluation scheme for the reliability of thermal power plant ...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the evaluation scheme for the reliability of thermal power plant equipment generally adopts the requirements of DL / T 793-2012, but it is mainly aimed at the unit level, although it also involves the evaluation of auxiliary equipment, but compared with the main The evaluation process of equipment and auxiliary equipment obviously cannot meet the requirements of actual work
