  • Technologies used in Power System Protection Systems
    2006 IEEE International Conference on Industrial Technology, 2006
    Co-Authors: Mohinder S Sachdev
    Abstract:

    The electromagnetic, electromechanical and solid state (analog electronic) technologies have been used in Protection Systems since the late 1800's. The developments in VLSI circuits prompted the use of analog electronics in designing and building protective relays. Since the introduction of microprocessors, their use in Protection Systems has been increasing gradually. The modern Protection Systems use them along with the needed analog electronics. The technologies used in Protection Systems are described in this paper. Some of the changes in the designs that have become possible due to the versatility of the present technologies are discussed. Some thoughts on the expected direction in which Power System Protection is likely to move are identified.

  • Modeling relays for use in Power System Protection studies
    Canadian Conference on Electrical and Computer Engineering, 2005
    Co-Authors: Sandro Gianny Aquiles Perez, Mohinder S Sachdev, Tarlochan S. Sidhu
    Abstract:

    This paper presents a new approach for modeling numerical relays. The models are embedded in the code of the electromagnetic transient program PSCAD/EMTDC. The software for modeling distance and differential relays (PLSA) is described in the paper. The inclusion of the models in PSCAD/EMTDC and their use in Power System Protection studies are addressed as well

  • A graduate program in Power System Protection
    2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2000
    Co-Authors: Tarlochan S. Sidhu, Mohinder S Sachdev
    Abstract:

    This paper briefly describes the Power System Protection program offered at the University of Saskatchewan. A brief account of the development of the courses and their outlines are provided. Laboratory facilities that are used in teaching, and providing hands-on experience in designing and applying relays in electric Power utility and industrial environments are described. The procedures used for designing, developing implementing and testing relays are also given.

  • A hands-on learning and training program in Power System Protection
    6th International Conference on Developments in Power Systems Protection, 1997
    Co-Authors: Mohinder S Sachdev
    Abstract:

    Postgraduate studies in electrical engineering have been an integral part of specialized training in several areas, such as Power System analysis, reliability evaluation, Power System control, System Protection, material science, analog and digital electronics, signal processing and communications. Most universities provide courses and training in all or some of these disciplines. The University of Saskatchewan has had an active graduate program in electrical engineering since the late 1950s. Training in Power System Protection is as important, if not more, for engineers working in electric Power utility and industrial sectors. It is interesting to note that, in North America, only a few universities offer courses in Power System Protection at the graduate and/or postgraduate levels. One of the universities that have offered courses for training in the area of Power System Protection for over thirty years is the University of Saskatchewan. This paper briefly describes the Power System Protection program offered at the University of Saskatchewan and outlines the facility that is used to provide hands-on experience in designing relays and applying them in utility and industrial environments. A brief account of the development of the courses in the program and the laboratory facilities is also provided.

  • A laboratory for research and teaching of microprocessor-based Power System Protection
    IEEE Transactions on Power Systems, 1996
    Co-Authors: Mohinder S Sachdev, Tarlochan S. Sidhu
    Abstract:

    This paper describes a laboratory which is used for conducting research and teaching in the area of microprocessor-based Power System Protection. The details of the facilities and their functions are presented. The use of the laboratory for specific research and teaching functions is outlined. Students' experiences with the use of the laboratory are also discussed.

  • Teaching Power System Protection with industry's cooperation
    IEEE Transactions on Power Systems, 1992
    Co-Authors: Anil Pahwa
    Abstract:

    Since 1988, the System relay engineer of Kansas Power & Light Gas Service has served as a guest lecturer for the course on fault analysis and Protection of Power Systems at Kansas State University. He meets the class five times during the semester. Two of these visits are field trips. In the other three visits he discusses Power Systems Protection from a practicing engineer's point of view. He also discuss a practical design problem prepared for this class. The details of the course, the design project, and other activities are described. The benefits of such cooperation between university and industry are outlined. The main objectives of this course are to: make the students familiar with symmetrical components and fault analysis; make the students familiar with computer methods for fault analysis; make the students familiar with directional overcurrent, differential, distance, and pilot Protection; impart practical knowledge on Protection to the students; are prepare students for projection-related jobs in the utilities.

  • Application of simulated annealing to Power System Protection assessment
    Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 1998
    Co-Authors: C. Singh, Ian A. Hiskens, P R Kumar
    Abstract:

    Simulated annealing has been applied to find the critical energy in an energy-based Power System Protection assessment algorithm. This critical energy is the minimum potential energy on surfaces defined by Protection operating characteristics. Simulated annealing converges reliably, even though the feasible region is non-convex. Convergence may be quite slow though. An adaptation which significantly improves the convergence rate by selectively suppressing the random direction is proposed and illustrated.
