摘　　要：针对智能电网调度控制系统在电网调控业务的未来模型和历史模型管理方面的不足,本文提出了一种基于应用与时间维度的电网模型多版本构建与管理技术,使用轻量级文件数据库与CIM/E文件作为多版本模型数据持久化存储介质,实现多个版本的安全隔离,以模型集为逻辑单元对电网不同业务模型进行分类,进而实现不同业务多时态模型版本构建与管理的技术方案,并对多版本间的模型比较与合并、未来版本模型验证与投在线流程管理等关键技术给出了具体的解决方案。该项技术已在调控中心试点应用,可满足多项业务应用对多时态版本模型的需求,提升了调控系统对未来模型构建、历史模型回溯、模型共享等方面的支撑能力。In view of the deficiency of the future model and historical model management in the smart grid dispatching and control system, this paper proposes a multi-version construction and management technology of power grid model based on application and time dimension. The method takes the use of lightweight file database and CIM/E files as the persistent storage medium of the multi-version model to implement security isolation among multiple versions. The different operational models are classified by logical model sets, and then the technical scheme of constructing and managing multi-temporal model versions among different transactions are realized. Furthermore, this paper proposes specific solutions for some key technologies, such as model comparison and consolidation between different versions, the model validation of future version and online process management. This technology has become a pilot application in the dispatching and control center for its ability to meet the demands of multiple business applications towards a multi-temporal version model, enhancing the supporting ability of the system control to construct the future model, backtrack historical model, model sharing and whatnot.
