State assessment method of direct current source system

Abstract

The invention discloses a state assessment method of a direct current source system. The state assessment method of a direct current source system includes the steps: acquiring the deterioration degree of the state quantity corresponding to each component of the direct current source system, performing normative processing to obtain the corresponding deduction value, calculating the comprehensivededuction value of each component through weighted summation, and obtaining the corresponding component assessment state; and detecting the component assessment state of each component, and if the component assessment states of all the components are normal states, determining that the comprehensive assessment state is normal state, or, determining that the comprehensive assessment state is the most deteriorated state among all the components. The state assessment method of a direct current source system has the advantages of providing determination basis with rich content, being comprehensivein the equipment coverage range, reasonably setting the state quantity assessment weight, truly and objectively reflecting the operating state of the covered equipment, being able to thoroughly findthe hidden trouble of equipment through direct current source system state assessment and predetermine the development trend of the defect of equipment so as to take preventative measures, strengthening direct current professional management work, promoting implementation of each measure through the assessment result, and carrying out operation and maintenance work.

Description

technical field [0001] The invention relates to a detection technology of a DC power supply system, in particular to a state evaluation method for a DC power supply system. Background technique [0002] The DC power system must run 24 hours a day, so once the DC power system fails, it must be charged to eliminate the defect, which poses a greater safety risk. In recent years, due to various reasons such as DC power system operation and maintenance management and equipment quality, there have been many primary and secondary equipment failures or accidents caused by failures of DC power systems such as battery explosions, fires, or failures of charging devices and monitoring devices. caused large economic losses. At present, there is still a lack of qualitative analysis and corresponding treatment methods for the reasons for the failure of various components of the DC system, some state quantities in the early stage of failure, and the impact on the DC system after failure. ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention: Aiming at the above-mentioned problems of the prior art, it provides a judgment basis that provides rich content, covers a comprehensive range of equipment, reasonably sets the evaluation weight of the state quantity, and truly and objectively reflects the operation status of the equipment under its jurisdiction. Based on the state evaluation method of DC power system, through the state evaluation of DC power system, hidden dangers of equipment can be found in depth, the development trend of equipment defects can be predicted, and problems can be prevented before they happen. maintenance work
