摘　　要：提出基于虚拟中心数据库的多数据源综合智能电力系统动态监视平台,该平台基于虚拟中心库实现不同应用系统的界面统一和数据共享,而不需对数据进行大量的转移和复制;采用考虑电力系统数据特点的高效无损数据压缩技术,提高平台对海量数据的实时存储和处理能力.并以该平台为基础开发基于PMU动态测量数据的各种电力系统监视和分析应用功能,主要包括低频振荡监视、电压稳定监视、电网设备参数识别和发电机组并网特性评估等应用功能.这些功能实现过程中,可以借助虚拟数据平台从其他监视和分析系统获取所需的数据,例如EMS或动态安全分析系统,分析结果也可以方便地与其他系统共享.A smart power system dynamic monitoring platform based on a virtual central database is proposed in this paper.It can realize platform uniform and data exchange between different application systems.There is no need to store and exchange large amount of data.In order to improve the real-time storage and management capacity for huge amount of WAMS data with high sampling rate,the system preprocesses the WAMS data according to the measurement data characteristics,and then the data is compressed by lossless compress algorithm.Many applications for power system dynamic monitoring and analysis have been realized,which includes low frequency oscillation monitoring,voltage stability monitoring,parameter identifications,and operation performance assessment for generators.The virtual central database can obtain the data from other monitoring and analysis systems,such as EMS and dynamic safety analysis system.And the analyzed results can be shared with the monitoring and analysis systems.
