Smart grid data analytics for digital protective relay event recordings

Information systems and intelligent smart grid data analytics will have a critical role in managing the massive amount of data becoming available in power system substations. Digital protective relays are multi-functional intelligent electronic devices based on microprocessors, which are being installed in substations throughout the power grid. New digital relays are replacing old-fashioned electro-mechanical or solid-state relays, and besides their protective function, they are coming equipped with monitoring capabilities. These monitoring capabilities are creating potential for better observability of power systems, redundancy in measurements, and improved decision-making process when operating the system. This article discusses the implementation requirements for a fully automated data analytics solution that provides data integration, fault analysis, and visualization based on the event data recorded by digital protective relays.

Dr. Kezunovic gives keynote speeches at prestigious conferences

Recently, a professor in the Department of Electrical and Computer Engineering at Texas A&M University gave keynote speeches during two prestigious conferences in Europe and Korea. The conferences had large attendance and their main focus was smart grid developments. Kezunovic’s talks were on the data harvesting in smart grids and uses of data for new applications.
EuroCon is sponsored by IEEE Region 8 and ISGC&E by the Korean Institute of Electrical Engineers. EuroCon is a multidisciplinary conference with a tradition of gathering experts from all electro-technical areas, electrical, electronics and information technology. For more about EuroCon, visit http://www.eurocon2013.org.
ISGC&E covers a wide range of studies, researches and products of smart grid development and welcomes research articles from researchers and engineers involved in various fields of Smart Grid from all over the world to present the state-of-the-art ideas and technologies.

New Trends for Automated Fault and Disturbance Analysis

In June issue of the PAC World magazine, Dr. Kezunovic is reporting on the latest activities of the CIGRE Working Group B20.

The goal of the report published as Brochure 424 in August 2010 is to serve as a guide for the application of automated fault and disturbance analysis systems. The purpose is not to cover the design issues because it is understood that the technology may evolve making particular design solutions quickly outdated but to analyze the methods and tools used in fault and disturbance analysis, the developments in technology and how they can be implemented in automated analysis systems.
