'Electrical Substations: Living With the Old' Course Description

This is a challenging time for utilities and their employees. Competition compels utilities to minimize costs wherever possible. Customers demand better service, including reliable, quality power. Operations and maintenance costs continue to rise, but at the same time there is pressure to reduce those costs. More critically, it is evident that much of the basic electric utility infrastructure is approaching the end of its design life. At the same time, demand for power continues to increase, placing higher stress on the already ailing facilities. Many of the experienced personnel needed to address these problems are poised for retirement and are not being replaced.

Can yesterday’s substations meet today’s demands? Should substation equipment be refurbished or should it be replaced? If replacement is the chosen option, what should it be replaced with? New advanced technologies can improve efficiencies and increase existing equipment and line ratings without adding facilities. For example, embedding intelligence in the power system can reduce the demands on executives, engineers, technicians, and operators. Industry professional needs to understand both the underlying analysis techniques and the new advanced technologies in order to assess the problems and address those issues effectively.

This seminar will examine these problems and present potential solutions. It will speak to advanced technology’s impact on maintenance, and examine strategies for evaluating the condition of the equipment. New and advanced technologies of the Intelligent Grid will be developed as they relate to the bulk transmission system, the distribution system, and the customer connection.

The course structure is unique in that the electric power-systems concepts required for an understanding of the focus material will be summarized in sessions distributed throughout the course. We will begin by introducing the Intelligent Grid and then clarify essential definitions, nomenclature, and relevant topics of power system analysis. Included later in the course will be intensive reviews of basic power calculations, power factor correction, simulation techniques for balanced and unbalanced short circuits (including symmetrical components), load flow, and power quality.

The instructors (the principal engineer of a consulting firm actively involved in power system refurbishment issues and an experienced professor of electric power systems) have designed the course to balance theory and up-to-date practice. Introduction of the relevant theory makes the course ideal for those who have been out of academia for some years, and for those utility personnel whose electrical background did not emphasize power system analysis.

The textbook and notes
As part of the course, each attendee will be provided a copy of a course textbook (to be decided)as well as a relevant set of notes. This material will be a useful permanent reference.
