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

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.
