Abstract

This paper presents electrical power distribution network reliability. Reliability is one of the most critical factors of a network operating system that is supported. Several things become essential parameters in determining an index that complements the distribution system, namely SAIFI and SAIDI. This research is able to know about the high levels obtained by the distribution system at the Wates substation. With this analysis, it is expected that this will become a reference for improving service quality in the coming year. Based on the results of calculations and analyses that have been done, it can be said that the distribution system at the substation has been reliable, because all feeders have met the standards set by the SPLN, IEEE, and WCS, especially the WT 05 feeder meets the standard.

Abstract

This paper presents the performance of the electrical power distribution network under dynamic loading. The performance of a distribution system can be seen from the power losses generated by the network. If the power losses are low, then it can be said that network performance is excellent. Another parameter is the distribution network voltage profile. The voltage profile is significant in the distribution network. A very long distribution line will cause a voltage drop at the end of the network. This condition is very undesirable, so efforts must be made to improve the distribution network voltage profile. The method for correcting the voltage profile is by installing capacitors or reconfiguring the network. In this study, an evaluation of the performance of the distribution network at PLN Temanggung was conducted. The results showed that several network points experienced below-standard voltage drops. Therefore it is recommended to install power capacitors or reconfigure the networks.
