Condition monitoring and analysis method of power transmission and transformation equipment based on Internet of Things technology

Abstract

The invention discloses a method for monitoring and analyzing the state of power transmission and transformation equipment based on the Internet of Things technology. The state monitoring and analysis system for power transmission and transformation equipment based on the Internet of Things technology is used for analysis; the analysis method includes: forming a state score of a single device, a state score Obtained by comparing the status monitoring quantity with the monitoring standard; after the status score of a single device is obtained, the status score of a single interval is formed; the status scores of all intervals of the equipment management unit are sorted, and the equipment problems that may exist in the problem interval are given at the same time. The equipment management unit shall make maintenance arrangements according to the system opinions, and the fraction and treatment opinions may be decided by the equipment management unit itself. The invention effectively improves the equipment state management level, saves unnecessary manpower and material resources, and has strong practicability.

Description

technical field [0001] The invention relates to a method for state monitoring and analysis of power equipment, in particular to a method for state monitoring, analysis and decision-making of power transmission and transformation equipment in substations, and belongs to the field of state monitoring and fault diagnosis of power transmission and transformation equipment in power systems. Background technique [0002] Power transmission and transformation equipment is the core equipment of the power system, and its health directly affects the stable operation of the power system. The maintenance of power transmission and transformation equipment is one of the key points of the power industry. At present, the common maintenance methods include post-event maintenance, regular maintenance and condition maintenance. In the current power system, regular maintenance is still the main method, and condition-based maintenance is coordinated. The main disadvantage is that regular mainten...

Problems solved by technology

[0004] 1) The equipment status information obtained by the online monitoring device is not comprehensive enough. The information often comes from a single or several sensors, and only corresponds to a certain type of equipment failure, without obtaining comprehensive equipment status information, which will affect the equipment status evaluation. accuracy

[0005] 2) Even if a number of different status information are selected for different fault types, the source of information is rich, but because the relationship between the online monitoring information is not considered, there is a lack of organic connection between the information, and the comprehensive processing and integration of information has not been realized. Collaborative analysis, which also affects the accuracy of status assessment

[0006] 3) Existing state monitoring data often only take online data, and there are few applications for offline data, so the state evaluation of equipment is not comprehensive and reliable enough

[0007] 4) The current condition monitoring technology is often aimed at a single equipment, without comprehensive consideration of a single compartment or all compartments of the equipment management unit, so the maintenance strategy given is less feasible
