多维度电网模型一体化存储与管理技术

Integrated Storage and Management Technology for Multi-dimensional Grid Model

智能调度要求完整、一致、准确、及时、可靠的电网模型数据支持。文中提出了一种多维度电网模型一体化存储与管理方法,以满足"横向集成、纵向贯通"和调度中心基于全电网模型的分析、计算以及智能调度等新型业务需要。该方法基于版本化分布式数据库建立了一体化存储与管理机制,将不同历史版本、不同地区、不同应用CIM/E格式电网模型数据统一存储于分布式数据库中。文中所提出的方法不但可以在时间维度上进行电网模型可追溯管理、在空间维度上实现各地区与全网模型统一存储,而且可以满足公共信息模型和私有应用模型存储与管理需求,此外,电网模型在分布式数据库中以增量方式存储,大大减少了冗余数据。

Intelligent scheduling requires support of complete,consistent,accurate,timely and reliable grid model data.This paper presents a method for integrated storage and management of multi-dimensional grid model to meet the “horizontal integration,vertical penetration＆quot;requirement and new-type business needs of the dispatch center based on the whole grid model such as analysis,computing,intelligent scheduling,etc.Based on visual,distributed database,an integrated storage and management mechanism is designed,with different historical versions,different regions,different applications CIM/E format grid model data all stored in a distributed database.The proposed method can not only have the grid model traced in time dimension,but also in spatial dimension various regions and the whole grid model can be stored together.Meanwhile,it can meet storage and management needs of the common information grid model and application grid model as well as the grid model distributed database storage incrementally,greatly reducing redundant data.
