Intelligent control system and method based on multi-channel cooperation

Abstract

The invention relates to the technical field of transformer substation operation and maintenance, in particular to an intelligent control system and method based on multi-channel collaboration, the control system comprises a dispatching automation master station system and a transformer substation system, and the two systems are in bidirectional multi-channel connection; and the control system isused for operation and maintenance control operation based on multi-channel cooperation. According to the system, multi-channel information automatic real-time switching, cooperative anti-error monitoring and multi-safety zone information fusion intelligent one-time anti-error control can be realized, and the command requirements of accident repair and rapid power supply recovery under extreme conditions are met; meanwhile, primary error prevention of the main station and primary error prevention of the station end are considered to be combined, compatibility with channels and part of functions of an existing automatic system is considered, investment is reduced, and limitation on the existing system and the functions is avoided.

Description

technical field [0001] The invention relates to the technical field of substation operation and maintenance, in particular to an intelligent control system and method based on multi-channel coordination. Background technique [0002] The operation of the existing substation requires the cooperation of on-site personnel and the dispatcher. After the on-site operation is inspected and confirmed, the operation result needs to be reported to the dispatcher. When both parties confirm that the operation result meets the predetermined operating procedure requirements, the dispatcher will allow the on-site personnel to For the next operation, these exchanges and confirmations are all carried out by telephone communication, so it takes a long time and requires more personnel, especially when dispatching or substation operators hand over shifts, the above operations need to be temporarily stopped until the shift is handed over Resuming the work after it is finished will make the opera...

Problems solved by technology

[0002] The operation of the existing substation requires the cooperation of on-site personnel and dispatchers. After the on-site operation is inspected and confirmed, the operation results need to be reported to the dispatcher. When both parties confirm that the operation results meet the predetermined operating procedure requirements, the dispatcher will allow the on-site personnel to For the next step, these exchanges and confirmations are all carried out by telephone communication, so it takes a long time and requires more personnel, especially when dispatching or substation operators handover shifts, the above operations need to be temporarily stopped until the handover Resume after completion, which will make the operation take longer and seriously affect the progress of the work

[0003] With the continuous development of science and technology in our country, modern substations are gradually moving toward informatization, networking, and automation. The continuous combination with computer technology, network technology, communication technology, and AI-assisted judgment technology has continuously improved its intelligence level. The operation of substations and The inspection has the technical conditions for comprehensive construction of intelligent operation and maintenance operations; on the other hand, the intelligent level of equipment in the substation has improved, and there are many intelligent systems, and the requirements for technical personnel are getting higher and higher. Manual operation and maintenance alone can no longer meet the timeliness and accuracy. In order to improve work efficiency and ensure the reliable operation of the substation

[0004] However, most of the existing substation intelligent operation and maintenance systems have a relatively simple structure, and the control method for misoperation only relies on the existing substation-side error prevention system, which cannot automatically correlate the information of the opposite side of the substation, and only considers local conditions of use. All the information of the intelligent application dispatching system does not have a complete and clear redundant structure concept, which cannot meet the high reliability requirements of unmanned intelligent operation and maintenance of the power system

The existing intelligent operation and maintenance control system in design and construction is a set of intelligent operation and maintenance special system built independently. The network connection between the main station and the sub-station is an independently designed or newly opened network channel. Consider redundant design with existing channels, not functional redundant design with existing systems
