This paper is a summary of an IEEE/PES Power System Relaying Committee (PSRC) report [2] on the design and testing of selected System Integrity Protection Schemes (SIPS). The report includes high level general considerations in SIPS design and testing, and the industry practice in design and testing of the following selected SIPS with example implemented schemes: (1) Generator rejection; (2) Load...
The IEEE PSRC System Protection Subcommittee Working Group C14 has produced a report that describes practical applications of synchrophasors in protection applications. The report begins with the history of synchrophasors and then goes into issues to consider in their application. Some existing applications are described and then future applications that have been considered or are in development...
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...
This paper proposes solutions for distributed protection applications, to improve current and design of future protection schemes. This solution utilises advantages of fast and reliable peer-to-peer communication of IEC 61850 and interoperability and configurability of IEC 61499. The integration of the two standards improves protection schemes by decreasing fault clearing times and minimizes the effect...
This paper addresses the subject of reducing outage durations and autorestoration applications within the distribution substation. Employment of intelligent electronic devices (IEDs) can aid in the reduction of the fault duration time, and also it enhances the protection, control, and monitoring at the distribution level. Further, communication among these IEDs can provide faster autorestoration,...
The basic concept of redundancy is simple. Instead of relying on a single piece of equipment, there are duplicate or triplicate sets that perform the same function. Consequently, if one piece of equipment fails, the function will still be performed by a redundant device. Redundancy of components plays a major role in elevating the reliability of protection systems. The impact on the power system when...
The double circuit or parallel transmission lines are more and more widely used in modern power system to improve transmission capability and reliability. Many types of relaying protection techniques can be used to protect parallel double transmission lines, such as over-current relay, distance relay and pilot relay[1]. Current and distance relays do not need communication channel but can not operate...
