Power Plant Electrical Distribution Systems
course provides an introduction to the design of electrical distribution systems
found in electrical power generation plants. The type of equipment utilized
in the electrical distribution systems is discussed in terms of its design,
function, role and backup capabilities.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
completion of this course one should be able to understand the role of the following
equipment in a power plant distribution system: Main electrical generator, isolated
phase bus duct, step-up transformer, station auxiliary transformer, non-segregated
phase bus duct, station startup transformer, medium voltage switchgear, secondary
unit substations, and motor control centers. Along with the role of each type
of equipment, one should understand how the equipment is utilized to provide
reliable power to the station.
Modern power plants
have an extensive electrical distribution system to provide reliable power to
all of the support equipment in the power plant. The utility operating the power
plant is in the business of generating electrical power twenty four hours a
day, seven days a week. Since electrical power can not be economically stored
the plants must be online to produce power when the electrical demand is present.
In this regard, the power plants must be highly reliable. Backup power sources
within the plant must be ready to supply needed power within moments. This course
will provide an overview of these systems and the relationships between the

This course has provided an overview of the major electrical distribution equipment in an electric generating power plant. The role of the generator, main transformers, medium voltage, and low voltage switchgear was explained. Although each power plant is different in its design, they are surprisingly very similar in their electrical distribution systems. Hopefully, this course has provided a sense of the magnitude of the scope in providing electricity to the consumer every day of the year.
