| 摘要: |
| 提出了一种基于虚拟仪器和公共对象请求代理体系结构(CORBA)技术的分布式电能质量监测系统实现的框架结构,实现对电能质量指标的测量和监控。系统由在线监测模块、数据传输、中心监控站和远程诊断中心等组成,实现了数据采集、分析处理、诊断和报警等功能。数字测量仪器采用实验室虚拟仪器开发平台LabVIEW软件开发,实现硬件测量功能。网络通信中采用CORBA技术实现异构环境下中心控制站与各监测仪之间的远程访问和控制。系统仿真和现场测试均表明该系统能够基本实现电能质量各项指标的监测和分析功能,并具有实时性好、可靠性高、开发成本低等特点。 |

| Abstract: |
| A framework of distributed power quality monitoring system based on virtual ins-trument and CORBA(Common Object Request Broker Architecture) technique is brought forward for the measuring and monitoring of power quality indices.The monitoring system consists of on-line monitoring instrument,data transmission,central monitoring station and remote diagnosis center,which realizes the functions of data acquisition,processing,diagnosis,alarm and so on.The digital monitoring instrument is developed by LabVIEW(Laboratory Virtual Instrument Engineering Workbench) software to realize the functions of hardware measurement.CORBA technique is used in network communication for remote access and control between central control station and monitoring instrument in isomeric environment.Simulations and field tests show that the proposed system can monitor and analyze power quality index,and is also real-timely,reliable and cheap. |
