EPRI: Protection, Automation, and Control
The PAC World Conference (Protection, Automation, and Control) is coming to American shores for the first time in 2014, and EPRI will be participating in several technical sessions in Raleigh on September 23-25. PAC World provides a forum for specialists from the protection, automation, and control disciplines to exchange ideas and experiences, discover new technologies or advanced applications of existing technologies, and discuss concepts and philosophies used around the world.
EPRI research will be featured in two sessions:
• Setting-less Dynamic State Estimation Based Protection [Tuesday morning, Sept. 23: The numerical relay has almost completely displaced electromechanical and solid state relays for power system protection and control. The capabilities of numerical relays, however, are not fully used, because they primarily mimic the logic developed for electromechanical relays. Recent developments in substation automation are using numerical relays for SCADA, communications, and as part of an integrated system for protection and control. EPRI is developing a new protection scheme based on dynamic state estimation along with several collaborators. Specifically, the protection scheme is based on continuously monitoring terminal voltages and currents of the component and other possible quantities such as tap setting and temperature. The monitored data are used in a localized dynamic state estimation model to continuously characterize the dynamic state of the component, which is then used to determine the health of the component. Laboratory tests have verified that microprocessors can perform the analytics required so that a setting-less protective device can operate continuously as would any other numerical relay. A pilot project has been approved for implementing the setting-less protection on a 765/345/13.8 kV autobank and a 765 kV, 150-mile transmission line.
• A Study of Testing and Maintenance Requirements and Approaches for Protection and Control Systems in IEC 61850 Substations [Thursday afternoon, Sept. 25: The International Electrotechnical Commission (IEC) 61850 standard introduces state-of-the-art communication technology to replace traditional wiring in the design of next-generation protection and control (P&C) systems. The use of communication networks in P&C designs, however, can bring practical challenges in equipment isolation, application testing, and system maintenance. The existing isolation practices and traditional testing tools that utilities are familiar with will become obsolete. To help address this critical technical barrier and expedite the field deployment of the IEC 61850 standard, EPRI launched a collaborative research project to specify utility requirements and develop viable interoperable approaches that could be applied for isolating, testing and maintaining multi-vendor P&C systems in a networked IEC 61850 environment.
