Method for assessment of operating state of turbonator

Abstract

The invention discloses a method for assessment of the operating state of a turbonator and relates to the technical field of electric generator state assessment. The method comprises the steps of acquiring operating state index data, taking operating state as a matter element to be assessed, converting each index into the characteristic of the matter element to be assessed, describing the operating state of the turbonator with a matter element model, establishing a matter element classical field model so as to describe the demand section of each operating state index about the magnitude range of each operating state grade, building a matter element joint domain model so as to describe the maximum value range of each index, calculating the correlation degree between each index of the matter element to be assessed and the operating state grades, determining the weight coefficient of each index of the matter element to be assessed, calculating the correlation degree between the matter element to be assessed and different operating state grades, and judging the grade of the operating state of the turbonator. By the adoption of the method, assessment and horizontal comparison of the operating state of the turbonator are achieved, a basis can be provided for reasonable arrangement of maintenance of power generation enterprises, and reliable operation of electric generators is guaranteed.

Description

technical field [0001] The invention relates to the technical field of generator state evaluation, in particular to a method for evaluating the operating state of a turbogenerator. Background technique [0002] The single unit capacity of generators in modern power systems is getting larger and larger, and large generators are the absolute main force in power production. At the same time, due to the high cost and complex structure of large generators, once damaged, the maintenance period is long, so it is required to have High operational reliability. [0003] As far as my country's current power shortage and power shortage situation is concerned, the annual running hours and full load rate of generators are much higher than before, and the spare capacity is very small, so its operation reliability is particularly important and prominent. On-line monitoring and evaluation of the operating status of large units can help operation and maintenance personnel arrange maintenance ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there is a lack of technology for scientific evaluation of the operating state of the turbogenerator, and there is no relatively comprehensive and unified index system for the evaluation index of the operating state of the turbogenerator. It adds a certain degree of difficulty. Based on this, it is particularly necessary to design a method for evaluating the operating state of a turbogenerator.
