Abstract:

企业资源整合是电力行业信息化的建设重点。作为调度自动化系统资源整合中心,综合数据平台提供了数据交换、数据整合、数据存储、数据查询等一系列服务。但是仅考虑横向互联的EMS系统模型信息整合,模型信息的准确性、及时性存在很大的局限。为了最大化地实现了多级调度系统之间的模型信息整合和共享,综合数据平台引入了分布式协同建模技术。文章基于IEC61970标准,提出了分布式协同建模技术在综合数据平台中的实现机制,探讨了分布式协同建模包含的多项关键技术,包括流程化模型信息收集、模型合并、图数模一体化的版本管理、WebServices等新技术。最后文中给出一个实际的工程用例,证明了分布式协同建模技术的实用性和可行性。实际案例是通过建立一套集运行、维护、数据采集、信息交换和信息共享为一体,部署在上、下级调度机构的分布式系统,实现了数据中心横向协同、纵向贯通的模型信息管理。
