WIND POWER SEMINAR: Practical Lessons from Wind Farm Collector Systems and Interconnections
Wanda Reder, VP of Power Systems Services at S&C Electric Company and President of IEEE PES
Wanda Reder will be our featured speaker presenting "The Wind Market and Practical Lessons Related to Plant Collector Systems and Interconnections". This presentation will cover the
wind energy development in the United States, review the turbine and tower, discuss the engineering requirements for the collector system and also highlight the modeling requirements for interconnections. She will conclude with some discussion on the typical structure for wind projects and lessons learned after completing them. Wanda will also be available to address any questions related to the direction and goals of the Power & Energy Society.
Wanda Reder is the Vice President of the Power Systems Services Division at S&C Electric Company offering engineering, field service, and project management capabilities to utilities, developers and industrial customers. Prior to S&C, Wanda was the Vice President of T&D Asset Management at Exelon where she had responsibility for asset investment strategy, standards, engineering, planning, reliability and work management in Chicago and Philadelphia. Prior to Exelon, Wanda was the Vice President of Energy at Davies Consulting.
Wanda received an Engineering Bachelor of Science degree from South Dakota State University and a Masters in Business Administration from the College of St. Thomas. Wanda has served on the IEEE Power Engineering Society Governing Board since 2002 and currently is the IEEE PES President. Since 2004, she has been researching the maturing power industry workforce and the challenge to attract and educate the necessary talent for our industry. To maintain expertise for power system reliability within the context of large pending retirement attrition, her efforts have resulted in collaborations to address the challenge with NERC, NRECA, EEI, PSERC, and IEEE (naming a few) to bolster the industry image, rebuild power related curriculums and transfer necessary knowledge.
Wanda has been instrumental in leading S&C into the Wind energy market. She capitalized on S&C’s expertise in contract development, substation and collector engineering and design, relaying, protection and coordination, SCADA, VAR management, and S&C’s world class consulting and analytical services. Under Wanda’s leadership, S&C now consults with the largest wind developers in the world; S&C has constructed the largest wind farm in Canada, and several wind generation facilities in the U.S.
The organizers of this seminar are the Boston Power Electronics Chapter, Boston Power & Energy Chapter, and IEEE North Shore Subsection. It will be held at the MIT STATA Center, Room 32-141, 32 Vassar Street, Cambridge MA 02139. To RSVP to this event to Soon Wan, gimsoon@ieee.org by September 21, 2008.

Pitt Falls of Calculating Arc-Flash Dangers – What is the IEEE 1584 Calculation Method?
What Are Two Common Errors with Bolted Fault Currents?
Peter R. Walsh, PE – Senior Field Engineer, Ferraz Shawmut, Newburyport, MA
Arc-Flash Dangers
What is Arc-Flash?
What is IEEE 1584?
What are the IEEE 1584 assumptions?
Does the 0.85 bolted fault current multiplier give rounded values legitimacy?
How safe is safe enough?
What is Arc-Flash?
Arc-flash is a short-circuit arc occurring in air that propagates extensive energy. The energy can kill at distances of several feet. They occur in circuits operating even below 600 volts. Clients are now asking their engineers to calculate the hazard risk categories
What is IEEE 1584?
This standard enables analysis and calculations specific to equipment and locations. It’s referred to as an accepted method by NFPA 70E. The IEEE 1584 calculations consider the effects of available bolted fault current and the over current protective device time-current characteristics.
What are the IEEE 1584 assumptions?
The conclusions about the arc flash danger and the available fault currents are counter-intuitive. Traditionally in a short circuit current study you could always round up and be more conservative. Arc flash can be different. A lower fault current can be a higher hazard level and often is.
Does the 0.85 bolted fault current multiplier give rounded values legitimacy?
The IEEE Standard states a procedure of multiplying the available fault current with a 0.85 multiplier and of taking the worst case. Is this standard procedure intended to compensate for an estimated bolted fault value?
How safe is safe enough?
The IEEE 1584 standard was mathematically developed to provide a 95% chance for recommending at least the correct PPE hazard risk category. Knowing the inherent assumptions in IEEE 1584 for safety, engineers can make safer PPE recommendations to their clients.
