CHATTANOOGA ENGINEERS CLUB http://www.utc.edu/~engrcs/cec/cec.htm Volume LI May 22, 2000 12:00 noon Number 19 The Cellar at Union Square THIS WEEK__________________________________________________________________ Bruce Pirtle, EPB's System Operating, will make a presentation on the new SCADA( Supervisory Control and Data Aquisition ) system. EPB's SCADA has been in design and implementation for several years. The scheduled completion date is December 2000. The comprehensive data collection system will enable operation personnel to control EPB's substation remotely. LAST WEEK___________________________________________________________________ Gary Forrester, project manager of the Apison substation, from EPB's Operating Division talked about the construction of the new Apison electrical substation in Collegedale. Mr. Forrester was responsible for the construction of this project. Many new ideas were incorporated into this substation. The project was environmentally responsible in the design and installation of environmental drains to protect surrounding areas in case of an oil spill. The design also incorporated microprocessor relays, which simplified the control wiring and added many new features not possible with mechanical relays. The presentation went through the construction from the initial grading work all the way to the completed sub. The Apison project was initialized with the EPB Engineering group. Due to the needed consideration with extreme voltage swings, high loading, and exposure related reliability problems, EPB initiated a joint study with TVA to find the most economical and practical solution. The long distance between a TVA source station and EPB substations is the cause of most of the problems with the power distribution in the area. The major power demand of the area is the McKee Baking Company. Therefore, EPB decided to add a ninth source station in Apison. The total project took less than three years. Engineering studies and property procurement took about one year. Construction took about one year and six months (including a three-month delay caused by El Nino). This substation has been in operation for almost one year and has performed perfectly. COMING PROGRAMS________________________________________________________ May 27 - Memorial Day, no meeting.
