Prediction of Harmonic Distortion in a Distribution System Caused by Housing Loads

Abstract
: This paper will di
scuss about impact of
nonlinear
load in residential costumer to harmonic distortion.
Electricity
consumer
behaviour
particularly
in
the household sector
with the development of
technology will
evolve
.
Equipment used
for
everyday purposes
continues to grow
and
has become a
lifestyle
.
The
modern life is
becoming fabulous with the invention of new technology, so that many more electricity utilities are used by
people and their houses in daily life. Nowadays, loads in the housing electricity utility do not only
contain of
linier loads, but also non
-
linier loads such as television, computer, microwave, fluorescent lamp and so on. The
problem uses
nonlinear
load is create harmonic distortion. The harmonic distortion will reduce the life time of
electrical equipmen
t and inefficiency. The purpose of this research is to do
modelling
and prediction of
harmonics level on housing electricity utility. The
modelling
and prediction of this research was using
harmonic
analysis
with ETAP PowerStation version 4.0.0 C. This exp
eriment was done in five houses as sample. The
measurement was done on non
-
linier load and Kwh
-
meter in every house using Fluke 41B. The result of
measurement on Kwh
-
meter on houses was compared in order to get the analysis result for VTHD, ITHD,
power fac
tor and frequency. The results research showed that VTHD, power factor (PF) and frequency on
house are comply to the normal standard. VTHD result (maximum 5) is

Beside those, ITHD on
house also comfortable to due standard, but there are house
es that did not comply into the appointed standard.
The analysis result showed that energy saving lamp cause the biggest harmonics level. The level of harmonics in
every house depends on how many electricity equipment used in it
