Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a method for automatically checking boundary conditions for executing planned maintenance of a distribution network. Background Art

[0002] With the rapid development of social economy, distribution network dispatching, as the command center of the power grid, faces the situation of increasingly complex power grid structure, increasingly difficult control, and overloaded operation of dispatching personnel. In order to ensure power supply reliability, reduce the impact of power outages on users, and improve the dispatching and operating personnel's ability to control the distribution network, it is necessary to establish a distribution network intelligent application system that can provide intelligent assistance, intelligent alarm, and intelligent decision-making to solve the dispatching personnel's problems in power grid safety, blind adjustment, work coordination, personnel efficiency, energy configuration, etc. At present, the information construction of Guangzhou Power Supply Bureau is developing rapidly, and the intelligence level of primary and secondary equipment and related supporting facilities of the distribution network is constantly improving. It has the functions of communication, monitoring, and control, and the technical foundation for panoramic monitoring, control, and management of the distribution network has been basically in place. The existing dispatching automation system and power distribution and use technical support system have carried out many distribution network application work related to distribution and dispatching operation in the real-time monitoring and management of power distribution, and have accumulated rich practical experience. However, the realization of comprehensive automation of the distribution network and the intelligent application combined with the requirements of the intelligent distribution network are still in the initial stage, and the work carried out is not comprehensive and in-depth enough, especially in the distribution of intelligent applications, distribution and use of power unified model and other aspects of technology and management blind spots.

[0003] As for the control of safety risks at work sites, power supply companies lack video surveillance and management of power work sites, and it is difficult to achieve on-site work risk control for all staff, throughout the entire process (before, during and after work), for all professions (substation maintenance, transmission maintenance, distribution operation and inspection, substation operation, power grid dispatching), and in multiple dimensions (power grid, equipment, operation characteristics, working environment, personnel factors, on-site risk sources, etc.) through remote information technology. It is difficult to discover and improve the weak links of productive units, and the pre-monitoring, in-process monitoring and post-inspection of production risks are unclear, resulting in a lack of standardization and refinement in production control, making it difficult to effectively prevent production safety risks, and not conducive to integrating risk control into actual production safety. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an automatic verification method for boundary conditions of distribution network planned maintenance execution, which solves the problem of safety risk management and control at the operation site. Power supply companies lack video surveillance and management of power operation sites, and it is difficult to achieve on-site operation risk management and control for all personnel, throughout the entire process (before, during and after the operation), for all professions (substation maintenance, transmission maintenance, distribution operation and inspection, substation operation, power grid dispatching), and in multiple dimensions (power grid, equipment, operation characteristics, operation environment, personnel factors, on-site risk sources, etc.) through remote information technology. It is difficult to discover and improve the weak links of productive units, and the pre-monitoring, in-process monitoring and post-supervision of production risks are unclear, resulting in a lack of standardization and refinement in production control and control, making it difficult to effectively prevent production safety risks, which is not conducive to integrating risk control and control into actual production safety.

[0009] S3: Finally, through the application of mobile application video operation and image perception technology, the on-site operation process is filmed with a mobile phone, and the video is transmitted to the DMZ area using video cutting technology, decoding compression technology and breakpoint resumption. The video data of the DMZ area is obtained in real time and associated with the PC operation ticket for playback.

[0010] Preferably, in step S3, while obtaining the video data of the DMZ area and associating and playing it with the PC-side operation ticket, after taking a picture of the on-site equipment status, the picture content is analyzed and the picture information is verified with the equipment status, thereby achieving safety and error prevention of on-site operations.
