8/18/2019 Electrical Power Supply System of the Power Plant to the Consumer

1/1

Electrical power supply system of the power plant to the consumer (load), is an

important thing to learn. Given the distribution of electricity, the process through

several stages of power plants producing electric energy, disalurankan to the

transmission network (SUE) directly to the substation. !rom the substation power

supplied to the primary distribution network (SU"), and through direct distribution

substations to distribution networks sekuder (SU#), electric power supplied toconsumers. hus the electricity distribution system functioning distribute electric

power to the wearer through the low voltage network (SU#), while a transmission

line serves to channel e$tra high%voltage electric power to the load centers in large

power (through the distribution network). Generating system (generation plant)

consists of one or more units that will convert mechanical energy into electrical

energy and should be able to generate enough electricity according to customer

needs. he transmission system serves to transfer electrical energy from units of

generation units at various locations with a long distance to the distribution system,

while the distribution system is used to deliver electrical energy to the consumer.

Electric power grid system is the distribution of electric energy from power plant

(power station) to reach the consumers (users) at the level of re&uired voltage. he

electrical power system consists of generating units, transmission units and

distribution units. Electric power distribution system can be divided into two kinds,

namely the distribution system of direct and indirect distribution system. 'irect

distribution system is a system of distribution of electricity conducted directly from

the entral ower lant, and not through the transmission network in advance.

'irect distribution system is used if the entral ower lant is located not far from

load centers, usually located load service area or suburban. *ndirect distribution

system is a system of distribution of electricity is done if the entral ower Station

far from load centers, so as to re&uire the distribution of electricity transmission

network as a network intermediary before being connected to the distributionnetwork deliver electricity directly to consumers. he primary distribution network is

the initial distribution of electricity from the ower lant !itness to consumers for

direct distribution system. +s for the indirect distribution system is the ne$t stage of 

the transmission network in an eort to deliver electricity to consumers. rimary

distribution network or high voltage distribution network (-') has a system

voltage of / k0. !or urban areas voltage above / k0 are not allowed, since the

voltage of 1/ k0 will occur corona symptoms that can interfere with radio

fre&uencies, 0, telecommunications, and telephone. he nature of the distribution

system services is very broad and comple$, because consumers should have served

a dierent location and haracteristics. he distribution system must be able toserve consumers who are concentrated in cities, suburbs and consumers in remote

areas. 2hile there karaktristiknya residential consumers and consumer industry.

onstruction systems distribution channel consists of the airways and underground

conduits. Selection of construction is based on the following considerations3 a

technical reason that the form of the technical, economic reasons, aesthetic reasons

and reasons of continuity of service is appropriate types of consumer services.
