Abstract

This paper discusses the determination of the reliability index of the power distribution system. The reliability of the power distribution system is strongly influenced by the duration and frequency of the disturbance, causing customers not to receive electrical energy. This reliability is measured by indices called SAIFI, SAIDI, and CAIDI. The method used to calculate the failure rate required to determine the reliability indexes are the section technique and Failure Mode Effect Analysis (FMEA). The results obtained using the FMEA method are better results. Compared to PLN's SAIFI and SAIDI standards, the Malili feeder is still quite reliable, because its value is smaller than the PLN standard. However, when compared to the IEEE standard, this Malili feeder is not categorized as reliable because the SAIFI value obtained is still higher. While for SAIDI the value is still below the IEEE standard. To improve the reliability index of this feeder, it is necessary to add a protection component to localize the fault.

Abstract

There are several types of photovoltaic system configurations, one of which is the on-grid PV system. This system is simple compared to other systems. Because there are two different energy sources that can supply the load either together or separately, an analysis of how the irradiation affects the electrical parameters on the load side or the grid itself is required. The goal of this research is to examine the performance of on-grid PV under various irradiation variation, type, and load power to power factor, grid frequency, and load conditions. To measure the performance of on-grid PV, parameter calculations are carried out in the form of PV efficiency, final yield, reference yield, and performance ratio, and the results of measurements of power factor, grid frequency, and load are observed due to variations in irradiation, type, and load power. The results show that the performance of on-grid PV is good; low irradiation can result in a decrease in the grid power factor, while the grid and load frequencies are in normal conditions for various variations of irradiation, type, and load power.
