Intelligent remote viewing system of transformer substation

Abstract

The invention discloses an intelligent remote viewing system of a transformer substation, relates to the technical field of power system control and particularly belongs to the intelligent remote viewing system of the transformer substation. The transformer substation intelligent remote viewing system is composed of a hardware system and a software system. The hardware system comprises a far-end computer, a station-end computer, an unmanned aerial vehicle image acquisition device, a remote control device and a monitoring device. The far-end computer, the monitoring device and the remote control device are connected with the station-end computer respectively through a wired network transmission mode; and the remote control device is connected with the unmanned aerial vehicle image acquisition device through a wireless network transmission mode. The software system comprises a remote control subsystem, an image analysis subsystem and an image storage subsystem all of which are applied to the station-end computer, an image transmission subsystem applied to the station-end computer, the monitoring device, the remote control device and the unmanned aerial vehicle image acquisition device, and an anti-collision subsystem and a device monitoring subsystem both applied to the unmanned aerial vehicle image acquisition device. The intelligent remote viewing system of the transformer substation ensures precision of image acquisition and also realizes full coverage of image information of the transformer substation.

Problems solved by technology

[0003] At present, each substation monitoring system adopts the traditional fixed camera installation method, which directly limits the field of view of the camera. There are video dead spots in the substation monitoring, and it is impossible to achieve full coverage of substation image information.

On the other hand, due to the fixed installation of the camera, the focusing ability of the camera cannot be maximized, resulting in the camera being unable to collect clear enough detailed information of the substation, such as: relay protection action information, protection pressure plate switching status and other information

[0004] In addition, the relay protection pressure plate of the existing substation is still checked regularly by manual operation, and the dispatching automation monitoring system is still in a blank state of monitoring

On the one hand, the method of manual regular checking cannot meet the real-time requirements of relay protection. Once the protection pressure plate is switched on and off by mistake, it cannot be found and corrected at the first time, which brings hidden dangers to relay protection misoperation and data movement; on the other hand, It is difficult to ensure the accuracy of the verification by manual verification, which increases the probability of protection misoperation and data movement

[0005] In addition, when an accident occurs in a substation, the dispatcher on duty needs to know not only the electrical quantity information of the grid, but also information such as substation images to guide the handling of substation accidents. The form of dispatcher's telephone report, but with the advancement of unattended substations, the operation and maintenance personnel are located far away from the substation. This method of image upload increases manpower and material costs and reduces work efficiency.
