چکیده مقاله:

Electric power systems must be monitored and controlled in order to maintain reliable operation. Historically this function has been performed by Supervisory Control and Data Acquisition (SCADA) systems or Energy Management Systems (EMS) consisting of sensors, transducers, Remote Terminal Units (RTU), and large mainframe computers. The technical factors which have driven the information industry way from mainframe computers technology towards a distributed network of numerous small computers (servers and workstations) also applies to the SCADA and EMS markets. Intelligent Electronic Devices (IED's) such as power monitors networked with personal computer based servers and workstations, using LAN and WAN technology are very suitable for onitoring and controlling power networks. This architecture provides superior real time power monitoring and control, historic data archival, power quality monitoring and energy delivery information capabilities. The use of a distributed software object architecture further enhances the power and flexibility of this approach. power monitoring system based on Power This paper discusses an implementation of a distri Measurement Ltd.'s Integrated Object Network (ION) technology including ION meters and the PEGASYS server and workstation software. The paper also discusses how enhanced functionality such as state estimation, transient analysis, load flow analysis, and expert systems can be easily integrated into the system by hird party software using tools such as Visual Basic, C, and Microsoft Excel, using standard interfaces. This is ability, to utilize the latest advances in computer hardware, software, human interface, and network technology. and the ability to develop applications or expert systems hich provide convenient local access to the information required by system operators, engineers, functional administrators, and managers in a form which is familiar and useful to them provides substantial advantages.
