“WIDE AREA COORDINATION OF PROTECTION” SEMINAR TO BE OFFERED BEFORE THE 2010 WESTERN PROTECTIVE RELAY CONFERENCE IN SPOKANE, WASHINGTON
Quanta Technology, ATG Consulting, and Electrocon International Jointly Sponsor Educational Seminar for Protection Managers and Engineers
September 13, 2010: Quanta Technology, ATG Consulting, And Electrocon International will sponsor a joint seminar, “Wide Area Coordination of Protection” on October 18, 2010 in Spokane, Washington, prior to the start of the 2010 Western Protective Relay Conference.
“Traditional approaches to protective relay setting are no longer enough,” says Tony Giuliante, President, ATG Consulting. This free seminar will help attendees learn more about Wide Area Coordination and why this more thorough approach to checking relays is now a practical way to enhance the performance of the protection system.
Event: Wide Area Protective Relay Coordination Seminar
Date: Monday, October 18, 2010 (prior to the start of the Western Protective Relay Conference)
Sponsored by: Electrocon International, Inc., Quanta Technology LLC, and ATG Consulting, Inc.
In this seminar, technical experts in protective relay wide area coordination studies will present the key concepts, tools, and techniques for performing Wide Area Coordination studies. Presenters will also discuss some of the hidden relaying problems that have been discovered in recently performed studies. The agenda is below. Although there is no charge for this seminar, attendees must register in advance to reserve a place. Protection managers and engineers can register at http://www.electrocon.com/contact.php; include “WPRC seminar” in your message.
Why Wide Area Coordination?
The traditional relay setting approach focuses on a specific group of protective elements applied to a single line. During the setting process, the engineer considers coordination only between preselected pairs of relay elements. With the complexity of multi-function and multi-criteria numerical relay designs and the tight operating conditions of modern power systems, this approach is no longer a viable way to check relays.
In contrast, the Wide Area approach looks at the coordination aspects of all adjacent protection systems one to two levels away for faults on a single line. The simulation area automatically includes protection on lines coupled to the study line. This way, the focus is not limited to the primary distance and overcurrent elements, but also on all the other elements that present a risk of misoperation. Detailed relay models can include differential elements, directional elements, fault detectors, fault identification logic, breaker failure, and automatic reclosing.
The ability to do rigorous, in-depth coordination studies is a proactive step that will enhance performance during system events. It may also provide supporting documentation for NERC compliance requirements.
