Example Embodiment

[0027] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The model management of the cloud standby dispatch center is derived from the regional main dispatch, and then the entire network is centrally spliced ​​under the premise of a unified boundary definition, and finally the entire network is incrementally maintained. The model exchange adopts the CIM / XML or CIM / E format based on the CIM standard, and the regional main dispatcher exports the full model, and the cloud backup dispatch center completes the incremental import of the model. The unified boundary definition was realized by automatic and manual methods at the initial stage, and later realized based on the CIM / E unified ID. Model data has the characteristics of strong structure and close relationship, and is suitable for storage in commercial relational databases.

[0029] The regional power grid model adopts the source-end ...

Abstract

The invention relates to a computer application method in the field of electrical automation and a system using the computer application method, in particular to a power grid dispatching automation main-and-standby system model synchronizing method and a synchronizing system using the power grid dispatching automation main-and-standby system model synchronizing method. A centralized cloud standby dispatching center is built, and whole power grid model united storage of graphs real-time data sections corresponding to a physical network model, a power grid calculation model and a power grid model is achieved. Any model maintenance operation of the cloud standby dispatching center is carried out through a standby dispatching maintenance center, region dispatching centers maintain static models in the jurisdiction scopes of the region dispatching centers respectively, the formed whole power grid model united storage ensures uniqueness of whole power grid models, and a unified model sharing access service mechanism is provided. The models of the region dispatching centers exist in the mode of views of full models, and are in self synchronization, so that service systems of the dispatching center can have access to the whole power grid models through standard and unified data access interfaces.

Description

technical field [0001] The invention relates to a computer application method in the field of electrical automation and a system thereof, in particular to a synchronization method and a synchronization system for a master and backup system model of a power grid dispatching automation. Background technique [0002] The domestic power system is characterized by hierarchical maintenance of power grid model data. Dispatchers at all levels own and maintain the topological relationship and electrical parameters of the power grid under their jurisdiction, and receive and process real-time data reflecting the operating status of their own power system in real time. Each network has established a relatively detailed power system model for the power grid within its jurisdiction, while the model of the adjacent power grid has been simplified and equivalent to a certain extent. This leads to the difficulty of data collection brought about by the wide-area distribution of power system da...
