摘要:
为了解决智能电网EMS系统因通信通道或设备误发、丢失以及延迟发送数据等原因而导致的数据通信故障，提出了一种基于多数据源校验的电网EMS数据质量在线监控方法。设计了一体化信息平台，采用通信监听技术，对来自不同数据源的同一个量测值进行比对，发现可能存在的数据质量故障，并对故障点进行诊断。借助一体化信息平台分布式架构特点，避免了传统集中式数据比对导致的效率低的问题。实际部署应用表明，基于分布式架构的多数据源比对平台，为电网EMS系统数据质量控制与快速故障诊断提供了一种自动校验的技术手段和方法，也为生产调度人员提供了一款功能强大的平台化分析诊断工具。

Abstract:
In order to monitor and diagnose the data quality problem due to communication failure, misinformation from intelligent electric device and data transmission delay of EMS, a kind of EMS data quality control and online monitoring method based on multiple data source calibration is proposed. An integrated information integration platform is designed, and traffic sniffer and decoding methods are adopted to obtain data from multiple source, the alarm and diagnosis procedures for different types of measurements are implemented for data quality monitoring and control. All those applications are integrated into the distributed system architecture, and compared to traditional concentrated system architecture, system efficiency is improved. Application shows that the system not only provides the techniques for automatically checking for data quality control and fault diagnosis, but also supplies a powerful platform for EMS maintenance.
Key words:  EMS  data quality control  multiple data source calibration  distributed system architecture
