Problems solved by technology

[0004] In the previous distribution automation system of power system, the inversion of historical accidents within a given time range has been realized, but such historical inversion has such limitations that it is necessary to Redrawing the plant and station diagram, if the dispatching system does not have protective measures for the previous plant and station diagram, directly modifying the original plant and station diagram will inevitably lead to historical inversion before the modification, the reason is very simple, the graph before the modification no longer exists up

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The technical scheme of the present invention strictly follows the functional specifications of the power dispatching automation system, and designs a method for saving the panoramic inversion context of the wiring diagram of the plant and station. The invention is mainly aimed at the method of performing panorama inversion of power grid accidents and context protection of plant and station wiring diagrams based on holographic measurement data with time marks during power grid operation.

[0022] In order to realize the holographic record of the operation of the power grid, the system integrates the real-time database into the dispatch automation system to store all the telemetry and telesignal data generated during the real-time operation of the regional power grid. The existing static parameters of power grid operation, model information, graphics, e...

Abstract

The invention discloses a method for saving factory station wiring diagram panoramic inversion context. An accident panoramic inversion component is added on the service layer of an existing dispatching automation system as the core component of power grid accident inversion in the system for all operations of relational databases and real-time databases in the dispatching automation system in the inversion process and used for providing data access, information access, power grid graph acquisition and inversion control interfaces for external applications. The control side of the accident panoramic inversion component will not be used to delete previous historical state diagrams automatically when a user modify original factory station diagrams, a historical state management service will be provided for each original factory station diagram, the service will be used to present time nodes of historical factory station modification in the man-machine conversation manner, so the historical factory station diagrams will be backed up unconsciously, so that historical period corresponding factory station diagrams and corresponding measuring point information can be synchronously displayed in the inversion process. Thus, the purpose that not only the factory station diagrams before modification can be protected and but also the factory station diagrams after the historical inversion can be continued can be achieved.

Description

technical field [0001] The invention relates to a method for saving a panoramic inversion context of a power plant wiring diagram, and belongs to the technical field of power system distribution automation. Background technique [0002] In the actual dispatching operation of power system distribution automation, accident inversion refers to recalling the trajectory of power grid operation for a period of time before and after the time of power grid accident. At present, the mainstream system serving power dispatching and production, that is, the dispatching automation system, uses relational databases. Persistent storage of data. Since the efficiency of relational databases cannot cope with millions of second-level sampling data of power grid operation, the storage cycle of power grid operation data in traditional dispatch automation systems is minute level. In order to realize the true inversion of power grid accidents, it is often stored for a certain period of time, such ...
