1. POWER SYSTEM

2. Introduction
• The power system is a network which consists generation,
distribution and transmission system. It uses the form of
energy (like coal and diesel) and converts it into electrical
energy. The power system includes the devices connected to
the system like the synchronous generator,
motor, transformer, circuit breaker, conductor, etc.
• The power plant, transformer, transmission line, substations,
distribution line, and distribution transformer are the six main
components of the power system. The power plant generates
the power which is step-up or step-down through
the transformer for transmission.

5. Defination of power generation
• Electricity generation is the process of generating electric
power from sources of primary energy.
• For utilities in the electric power industry, it is the stage
prior to its delivery to end users
(transmission, distribution, etc.) or its storage (using, for
example, the pumped-storage method).
• Electricity is not freely available in nature, so it must be
"produced" (that is, transforming other forms of energy
to electricity).

6. • Production is carried out in power stations (also called
"power plants").
• Electricity is most often generated at a power plant
by electromechanical generators, primarily driven
by heat engines fueled by combustion or nuclear
fission but also by other means such as the kinetic
energy of flowing water and wind.
• Other energy sources include
solar photovoltaics and geothermal power.

7. Power stations
• An installation where electrical power is generated for
distribution
• A power station, also referred to as a power plant and
sometimes generating station or generating plant, is an
industrial facility for the generation of electric power.
• Power stations are generally connected to an electrical grid.
• Many power stations contain one or more generators, a
rotating machine that converts mechanical power into three-
phase electric power.
• The relative motion between a magnetic field and
a conductor creates an electric current.

8. Types of generations
• Steam power stations
• Hydroelectric power stations
• Nuclear power stations

17. • Transmission lines are sets of wires, called conductors, that carry electric
power from generating plants to the substations that deliver power to
customers.
• At a generating plant, electric power is “stepped up” to several thousand
volts by a transformer and delivered to the transmission line.
• At numerous substations on the transmission system, transformers step
down the power to a lower voltage and deliver it to distribution lines.
• Distribution lines carry power to farms, homes and businesses.
• The type of transmission structures used for any project is determined by
the characteristics of the transmission line’s route, including terrain and
existing infrastructure.

Present and future ………….

28. • Supervisory control and data acquisition (SCADA) is
a control system architecture comprising computers,
networked data communications and graphical user
interfaces (GUI) for high-level process supervisory
management, while also comprising other peripheral
devices like programmable logic controllers (PLC) and
discrete proportional-integral-derivative (PID) controllers
to interface with process plant or machinery.
• The use of SCADA has been considered also for
management and operations of project-driven-process in
construction.
