Abstract

Harmonic is one of sinusoidal components, one wave period from which having multiple frequency of its fundamental frequency one, leading to electrical power quality problems. Harmonic distortion in term of voltage and current ones, generally is due to non linier impedance. Inverter is one of example of it. There are some items that will be measured. There are value of harmonic at  source and value of voltage and current harmonic when inverter does not have any load. IEEE Standard of 519-1992 as a reference in determining maximum limitation voltage and current harmonics. The result of the tests were showed that voltage harmonic distortion at inverter did not exceed the IEEE 519-1992 maximum limitation of 5%. While current harmonic distortion had exceed the maximum limitation of the IEEE 519-1992. The highest results were exceeding 57,52 % when inverter does not have any load. After using passive filter that function for reducing the value of harmonic,  the total harmonic distortion (THD) current w only 6,837%  when inverter does not have any load.   Keywords : Voltage, Current, Harmonic Distortion, Passive Filter.

Abstract

System distribution has used 13 of loads with source of generation from substation. It will be simulated on EDSA Technical 2005 in bad weather that occur in system during one month. Probability of bad weather occurance is 8,33%/year with failure rate almost twice than normal condition, about 2000%. The result shows that weather contributes significant influence for reliability of distribution system although the bad weather happened in short time. Keyword : failure rate, reliability, distribution system.

Abstract

The reliability of the distribution system will give direct impact to power supply availability. By adding some DG to a distribution system increase the reliability of the distribution system. The research aims to analize the impact of installing DG in a distribution system to system reliability. There were  fourth case studies in this research. The first one was the study of reliability of a distribution system without DG. The second and the rest ones were DG installing to system in different bus location. In order to be able to calculate parameters needed for the distribution reliability such as system reliability index,  EDSA Technical 2005 software was used. The result of research show that by installing DG to each load bus always give improvement to system reliability in each load. The optimum reliability was obtained when DG was install at bus 4. Keywords: reliability, distribution system, DG and EDSA.

Abstract

Voltage and current harmonics produced by nonlinear loads which reduce electrical power quality and energy saving lamp is one of example of it. This research was done by performing studies in harmonic voltage and harmonic current from four different brands of energy saving lamp having power rating of 8 watt, 16 watt, and 20 watt and uses IEEE Standard of 519-1992 as a reference in determining maximum limitation voltage and current harmonics. The result of the tests were showed that total harmonic distortion (THD) voltage at each different brand of energy saving lamp having power rating of 8 watt, 16 watt, and 20 watt did not exceed the IEEE 519-1992 maximum limitation of 5%. While total harmonic distortion (THD) current at each different brand of energy saving lamp having power rating of 8 watt, 16 watt, and 20 watt had exceed result range exceeding 71,2%. After using low pass RC filter as passive electronic circuit, the total harmonic distortion (THD) current was obtained for each different brand of energy saving lamp having power rating of 8 watt, 16 watt, and 20 watt, it was showed that the range of total harmonic distortion (THD) current under 14,262%.
