Problems solved by technology

[0005] 1. Through real-time online monitoring, only the abnormal conditions that have occurred can be found, and the abnormal conditions that will occur cannot be predicted, and the hidden dangers of the power transmission equipment cannot be found, and the hidden dangers cannot be eliminated in advance, and it is impossible to prevent problems before they happen, that is, Said that the problem could not be detected in advance
[0006] 2. Through automated and intelligent online monitoring, users can only be notified of the monitored situation, and specific decisions still need to be made by users. There is no automatic decision-making function and control function, which means that they cannot actively solve problems
[0007] 3. All the monitored data are sent to the server for centralized processing. Since the number of power transmission equipment in the smart grid is huge and scattered, the amount of monitored power transmission equipment status data is huge. This centralized processing method will immediately Causes a large communication overhead, and also causes delay, affecting real-time performance

Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0056] At present, the monitored state data of power transmission equipment mainly includes:

[0057] 1. Meteorological monitoring

[0058] 1) Micro meteorological environment monitoring: light radiation intensity, wind direction, wind speed, standard wind speed, maximum wind speed, maximum wind speed, air pressure, temperature, rainfall, precipitation intensity, humidity;

[0059] 2) On-site pollution degree monitoring: daily minimum humidity, daily maximum humidity, daily minimum temperature, daily maximum temperature, insulator salt density (ESDD), dust density;

[0060] 3) Icing monitoring: deflection angle, comprehensive tension, ice thickness, comprehensive tension, unbalanced tension difference, wind deflection angle of insulators.

[0061] 2. Wire monitoring

[0062] 1) Wire sag monitoring: wire-to-ground distance, wire sag;

[0063] 2) wire tempe...

Abstract

The present invention provides a state data feedback system and method for distributed power transmission equipment. The system includes: at least one monitoring device, at least one community monitoring platform, at least one large area monitoring platform, and a general monitoring platform. The present invention can discover problems in advance, actively solve problems, and can efficiently process and feed back the state data of power transmission equipment in real time, and the fault prediction is accurate and efficient.

Description

technical field [0001] The invention belongs to the field of smart grids, in particular to a state data feedback system and method for distributed power transmission equipment. Background technique [0002] In recent years, the smart grid (Smart Grid, SG) has been developing continuously. In the process of SG research and development, the power grid itself has become increasingly large and complex, and the voltage level has been continuously improved, which puts forward higher requirements for the real-time performance, stability and safety of power transmission equipment. [0003] At present, in order to avoid the "compulsory repair when due" and "treatment of minor illnesses or even treatment without disease" caused by periodic inspections, the inefficiency caused by manual inspections, and the "inefficiency" caused by regular inspections Insufficient maintenance” problem has adopted the real-time online monitoring technology of transmission equipment status. For example...
