Generation of Electricity And the Electricity Grid

Power Plant

also referred to as a _______ and sometimes a generating station or generating plant, is an industrial facility for the generation of electric power.

Electromagnetic Induction

a current produced because of voltage production (electromotive force) due to a changing magnetic field.

Michael Faraday

Electromagnetic Induction was discovered by ____ ________ in 1831

Number of Coils
Changing Magnetic Field

factors that influence this voltage production.

Generators

a rotating machine that converts mechanical power into three-phase electric power.

electric motor

a machine that converts electrical energy into mechanical energy.

Stator

refers to the stationary component in an electric motor or generator.

rotor

(the rotating part) spins.

steam turbines

Most of the electricity in the Philippines is produced in ____ _______

turbine

converts the kinetic energy of a moving fluid (liquid or gas) to mechanical Energy

power distribution grid

Electrical power travels from the power plant to your house through a system called the ____ _____ _____

National Grid Corporation of the Philippines (NGCP)

who is the transmission system operator in the philippines

transmission system operator

It is in charge of operating, maintaining, and developing the country's state-owned power grid, controls the supply and demand of power and updates the daily power situation outlook for Luzon, Visayas, and Mindanao power grids

Transformer

a device that transfers electric energy from one alternating-current circuit to one or more other circuits,

Step-up transformers

a type of transformer where it convert low voltages to high voltages.

Step-down transformers

A type of transformer that converts high voltages to low voltages.

25000

A power plant generates around ____V

240

A step-down transformer outside your house steps the voltage down to ___V

20000

A distributing substation steps the voltage down to _____ V

100000

A substation steps the voltage down to ____ V

345000

A power station steps up the voltage to ______V so it can be transferred through power line

Substation

a part of an electrical generation, transmission, and distribution system.transform voltage from high to low, or the reverse, or perform any of several other important functions.

distribution transformer

is a transformer that provides a final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer.

pole-mount transformers

If a transformer is mounted on a utility pole, they are called __________

pad-mounted transformers

If the distribution lines are located at ground level or underground, thus known as __________.

Single Phase

a two-wire alternating current (ac) power circuit. Residential homes are usually served by a single-phase power supply.

Three Phase

a three-wire ac power circuit. Commercial and industrial facilities usually use a three-phase supply.

230V 60Hz

The main voltage and frequency to be used for the load schedule. It is the mean voltage and AC power most residence receives

Rectifier

an electrical component that converts alternating current (AC) to direct current (DC).

Inverter

An electrical component that converts to direct current (DC) to alternating current (AC).

Private Distribution Utilities

electric distribution companies that are owned by private entities.
