Problems solved by technology

[0006] (1) The number of current substations is increasing, the number of operation and maintenance equipment is increasing, and the number of personnel does not match the number of equipment
[0007] (2) During the process of manual inspection of equipment, it is greatly affected by the physiological and psychological quality, sense of responsibility, external working environment, work experience, and technical level of the personnel, and there is a possibility of missed inspections and missing defects.
[0008] (3) The inspection task of power station equipment is heavy, and long-term repetition of the same mentality will cause disgust and paralysis of this work, resulting in hidden dangers of safety accidents
[0009] (4) The equipment inspection task is affected by external climate and geographical factors, and it is impossible to know the situation of the power station in time
[0010] (5) Most of the power station end systems are mutually independent systems, and resource sharing / linkage control cannot be realized between each other
Unable to maximize resource utilization

Embodiment 1

[0040] like figure 1 As shown, the substation equipment abnormal intelligent inspection system in this embodiment includes a controller, a video monitoring system connected to the controller, a fire protection system, a dispatch automation system, a protection information system, an online monitoring system, a unified asset equipment information system, and a robot inspection system. system, drone cruise system, intelligent lighting control system and access control system;

[0041]Among them, the controller compares the collected images of equipment abnormalities, and the input device of the controller monitors the alarms of the equipment abnormal inspection system, and obtains alarms or task information of switching quantities, analog quantities, and network input quantities of equipment or systems; When receiving equipment and system alarms or inspection tasks, the controller controls the UAV system, video surveillance system, and robot inspection system to collect on-site ...

Embodiment 2

[0056] like image 3 As shown, based on the system and method of Embodiment 1, the abnormal conditions of the primary equipment are as follows:

[0057] Intelligent inspection of main transformer abnormalities:

[0058] Troubleshooting of abnormal sound: When there is a sound of "gurgling" water boiling inside the transformer, it may be caused by serious faults in the winding or poor contact of the tap changer and local severe overheating.

[0059] The sound of the transformer increases significantly, and when there is a crackling sound inside, immediately disconnect the transformer circuit breaker and transfer the transformer to maintenance. When there is a crackling sound in the sound, it is loud and uneven, and it may be that the insulation of the transformer body has broken down. When the above abnormalities are detected through the installation of equipment, the intelligent inspection management platform sorts out the information and uploads it. Oil temperature and oil...

Embodiment 3

[0061] like Figure 4 As shown, based on the system and method of Embodiment 1, the abnormal situation of the circuit breaker is as follows:

[0062] Opening and closing failure:

[0063] The robot or UAV monitors and captures the action points of the installed equipment and transmits them to the command platform.

[0064] Abnormal SF6 gas:

[0065] Extract the abnormal point data of SF6 gas background monitoring and send it to the command platform.

Abstract

The invention relates to an abnormal intelligent inspection system and method for substation equipment. The system comprises a controller, and a video monitoring system, a fire extinguishing system, adispatching automation system, a protection information system, an online monitoring system, a unified asset equipment information system, a robot inspection system, an unmanned aerial vehicle cruisesystem, an intelligent light control system and an access control system which are connected with the controller. With application of the system and the method, investment of manpower and material resources is reduced, the risk of traffic personal injury caused by departure of operation and maintenance personnel is avoided, the resource utilization and distribution are more reasonable and visualization and intellectualization of substation inspection work are achieved so that the inspection period is prolonged and even manual inspection is replaced, the accuracy and the timeliness of data entry are guaranteed, the whole equipment abnormal inspection process is unmanned and the network security risk of a power grid system caused by the production equipment and the production area network is eradicated.

Description

technical field [0001] The invention relates to a patrolling system, in particular to an intelligent patrolling system for substation equipment abnormality, and also relates to the patrolling method. Background technique [0002] With the development of the economy, the number of substations is currently increasing, and the number of operation and maintenance equipment is increasing. The number of personnel has not matched the number of equipment. [0003] Due to the increase in the number of unattended substations, many substations are also far away. When accidents occur in the station or after strong winds, heavy snow and thunderstorms, the centralized control station cannot get out of the car and cannot patrol in time, resulting in the on-duty personnel of the centralized control station. , Timely discovery of hidden dangers, endangering the safe operation of the power grid. In particular, it is impossible to keep abreast of the situation of substations that have problem...
