Description

Technical Field

[0001] The present invention relates to the technical field of automatic control of electric power systems, and in particular to a method, system and device for interaction of services between a dispatching system and a centralized control system. Background Art

[0002] After the substation is connected to the centralized control system, the operation of the substation is generally carried out in the centralized control system. However, the interaction specifications have not yet been formed between the centralized control system and the dispatching system. The substation that has been connected to the centralized control system still needs to maintain information interaction services with the dispatching system, resulting in "double transmission" of substation graphics and operation information. Remote control and remote adjustment can be "double-controlled" by the centralized control system and the dispatching system, while operations such as listing need to be "double-operated" by the centralized control system and the dispatching system. This leads to inconsistency between the graphics of the centralized control system and the dispatching system, and it is difficult to divide the remote control and remote adjustment monitoring and acceptance authorities. Operations such as listing need to be "double-operated" in two systems, which increases the user's workload. Summary of the invention
