摘　　要：在目前的电网调度自动化系统中,电网模型的版本管理还局限在对其时间维变化的内容进行管理的方式。文中提出一种基于模型集和差异模型的电网模型多版本管理方法,将空间维和应用维模型通过模型空间和模型树的类型划分成相应的版本空间,以模型集为基线,通过叠加不同时间生效的差异模型实现对空间、时间和不同应用维度模型的多版本管理,提升了对历史模型回溯、未来模型建模、应用模型转换的灵活性,实现了实时电网监控运行与历史、未来电网研究分析在电网模型层面的协调统一,满足了电网调度控制中心内各业务应用对时间、空间和应用维电网模型开展研究分析的需求。In the current power grid dispatching automation system, the version management of model is confined to the management of time dimension information changes of the grid model. A multi-version managing method of the grid model is proposed based on the model set and the difference model. The method consists in dividing the model of application and space dimension into the corresponding version space. By using the model set as a baseline and the superposition of difference models with different effective time, the multi-version management is able to improve the flexibility in retrospecting model history, modeling future models and transforming the application models. It is capable of realizing the harmony and unification of real- time monitoring of the power grid and the historical and future grid analysis on the level of power grid models, satisfying the demand for analysis of researches on the three dimensional grid of time, space and application by the power grid dispatching control centers.
