Power system dispatchers throughout the Eastern Interconnection (EI) of the United States regularly observe unusual frequency movements during the Super Bowl championship game of American football. While these movements have not been a threat to security to date, they are large enough to warrant explanation. We have found the explanation for these frequency movements through load and frequency mon...Show More
The globally used COMTRADE standard was initially developed by IEEE and later adopted by IEC. The first IEEE version was published in 1991 and was later revised in 1999. The IEC version was adopted in 2001. The 2013 revision of the COMTRADE standard is an IEEE/IEC Dual Logo standard planned for publication during the first quarter of 2013. The main motivations for the current revisions are: 1) to ...Show More
The Eastern Interconnection frequency governing characteristic, sometimes called Beta, has been tracked by one of the authors for a period of more than 15 years. While there are some errors inherent to the process followed, we believe that the errors do not obscure the overall trend. We have found that Beta has been declining and has reached a level of approximately 25 MW/mHz. This has important i...Show More
Two electric utility control areas independently adapted existing system data collection software to capture the response of the units within their several utilities' generation before, during, and after the loss of large blocks of generation [ranging from 1000 MW to 2200 MW] during periods of otherwise normal operation. These measurements are essentially unannounced tests of the governing respons...Show More
The authors have systematically kept track of Eastern interconnection frequency governing characteristic, called beta, for a period of more than 10 years. While there are some errors inherent to the process followed, we believe that the errors do not obscure the overall trend. We have found that Beta has been declining, and has reached a level of 31 MW/mHz. The true beta is probably somewhat lower...Show More
The integration of multifunctional IEDs with protection, control, monitoring and recording functions in UCA 2.0 or IEC 61850 based substation automation systems results in the implementation of distributed systems for monitoring and recording in substations or power plants. Different types of abnormal system conditions at the distribution, sub-transmission and transmission levels of the power syst...Show More
In 1992, the New York Power Authority (USA) and the other Empire State Electric Energy Research Corporation member electric utilities initiated the deployment of a network of power system synchronized measurement units using phasor measurement technology on the New York State high-voltage transmission system. This article defines the current and future status of the measurement network, featuring ...Show More
This paper summarizes research and operating experience related to the effects of geomagnetically induced currents (GIC) on protective relaying. It shows that if the GIC causes high levels of harmonic distortion, there is a risk that the conventional protection system may not provide adequate protection for the capacitors, transformers, and generators. It recommends methods to reduce the risk of f...

Power line carrier (PLC) is a popular method of communicating protective relaying information between line terminals of a protected power transmission line. This paper describes the results of a 1990 survey of utility engineers on their PLC equipment selection and applications, and PLC equipment maintenance practices and problems.<>Show More
The latest of a series of lists of papers on power system relaying, begun in 1927, is presented. The 216 papers listed for 1988-1989 include papers on the subjects of service restoration, testing and methods of calculation, as well as of relaying. Only the more readily available foreign publications are included. Each reference includes the title, author, publication information, and a very brief ...

Bibliography of relay literature, 1986-1987

J. Ingleson

IEEE Power Engineering Review
Year: 1989 | Volume: 9, Issue: 7 | Magazine Article |
This bibliography is the latest in a unbroken series of bibliographies of relaying papers covering the years 1927 through 1987. areas, making categorization difficult. Papers published over the past two years reflect the many ways computers are used in relaying, including microprocessor based relays, computer protections systems, as an aid to the relay engineer in his work, for relay testing, and ...Show More

Bibliography of relay literature, 1986-1987

J. Ingleson

Year: 1989 | Volume: 9, Issue: 7 | Magazine Article |
The latest of a series of classified lists of power system relay references, begun in 1927, is presented. This bibliography is a continuation of similar bibliographies of relay literature which have been published previously and are contained in the following volumes of this Transaction: 1927-1939, Vol. 60, 1941; pp. 1435-1447 1940-1943, Vol. 63, 1944; pp. 705-709 1944-1946, Vol. 67, pt. I, 1948; ...Show More
