The Energy Management Systems (EMS) were invented in the seventies to add computationally intensive applications to the Supervisory Control and Data Acquisition (SCADA) Systems which were introduced as the core infrastructure for scanning the field data in the sixties. Over the last 50 years many EMS functions were implemented and SCADA was further enhanced. Recently, limitations of low scanning capability...
On-line power system analysis enables to make power mode-related decision based on information available at real time. The quality of the studies and efficiency of power system operation are closely associated with the accuracy of the power system models. Accurate and quick decision based on analysis on real time data has been necessary for making operational plan under the deregulation of power system...
On the basis of studying the real-time database technology, combined with CC-2000A system of Kedong company, the CASE management functions is being developed, which improved the history data processing method in the real-time database of SCADA (Supervisory control and data acquisition systems). It can achieve the goal of preserving, recovering and deleting the entities of real-time database, graphics...
During 2006-2008, the Electrical Research Institute in Me??xico developed an on-line simulator of the electric distribution system (distribution network) for Comisio??n Federal de Electricidad, the main electric utility in Me??xico. The simulator was installed in a regional distribution control center in Tampico, Tamaulipas, Me??xico. In the functional specification stage, a requirement was detected,...
NSTAR is an investor owned utility transmitting and delivering electricity and gas to customers in Eastern and Central Massachusetts. In the process of becoming a Local Control Center, which allows NSTAR to work more closely with the Independent System Operator - New England (ISO-NE), NSTAR upgraded its SCADA system and added an integrated Energy Management System (EMS) in 2007. In anticipation of...
Eskom's Transmission division is commissioning a new Energy Management System (EMS) known as TEMSE. This EMS included requirements for advanced alarm processing facilities and enhanced Human Machine Interface functionality. The requirements covered alarm data reduction and the provision of "what-happened" explanations following a disturbance on the power system. The implemented functionality...
