Abstract

There are 2 methods of placing the Arrester and Fuse Cut Out (FCO) as protection at  distribution substation, namely the placement of the Arrester before the Fuse Cut Out (FCO) and the placement of the Arrester after the Fuse Cut Out (FCO). Each method has a different impact in overcoming the coming lightning implosion voltage disturbance. The purpose of this study is to determine the effect of arrester placement before and after FCO on distribution transformers on lightning surge interference, and to find out how the performance of arresters and FCO when lightning surge interference occurs. In this study there are three calculations, namely the calculation of the arrester placement before the FCO, the calculation of the arrester placement after the FCO and the calculation of the maximum protection distance of the lightning arrester with the transformer. The results of this study are the placement of the Arrester before the FCO, the surge voltage that passes to the primary side of the transformer is 53,8567 kV/ µs, this value is still below the transformer TID of 125 kV. Then in the Arrester placement after the FCO the surge voltage that passes to the primary side of the transformer is 58   kV/ µs, this value is still below the TID of the transformer of 125 kV. The maximum distance of arrester placement to the transformer is 14,1 m. The conclusion of this research is that the arrester works optimally in the two placements as for FCO does not work well in the Arrester placement after FCO.

Abstract

Research has been conducted on lightning strikes with rainfall to determine the relationship between the two. The problem in this study is how the relationship between lightning clouds to the ground with rainfall in Pontianak City. The lightning data used is lightning detector data originating from the BMKG Supadio Station and rainfall on the BMKG website. The method used in this study performed a linear regression test and a correlation test using the Spearman correlation method. The results obtained show a relationship between rainfall and cloud lightning to the ground daily with a Spearman correlation of 0.2237 which means that the relationship between the two variables has weak strength. The strength of the relationship between the number of cloud lightning strikes to the ground with low rain intensity and the 22.37% relationship between rainfall intensity and the number of cloud lightning to the ground. The correlation coefficient obtained is positive. The relationship between the two variables is unidirectional and can be interpreted that high rain intensity will cause the number of lightning strikes to increase. The intensity of rainfall determines less the size of the number of cloud lightning strikes to the ground. The correlation value between the number of cloud lightning strikes to the ground and the intensity of rainfall in Pontianak City in the weak correlation category with a small value (R2) close to zero. The coefficient of determination is 0.088. This means that 8.8% of the variation from lightning strikes can be explained by variable variations in rainfall.

Abstract

A generator is an electrical device that functions as a tool that can convert mechanical energy into electrical energy. Generator efficiency will affect the performance of the PLTU system, the greater the generator efficiency, the better the generator efficiency, therefore generator efficiency is an important thing to maintain the quality of electrical energy that will be distributed to consumers. The aim of this research is to calculate the influence of fluctuating turbine power on generator efficiency using the Steam Property mobile application. Based on the average value obtained, the efficiency of the unit 1 power plant is 87.46%, with an average load of 4.26 MW and actual turbine power of 4.88 MW. The lowest efficiency display occurred on day 1 with an efficiency of 78.83%, while the highest efficiency value occurred on day 5 with an efficiency of 91.28%. Changes in the load on the generator affect the generator efficiency value which is followed by changes in actual turbine power, where if the load value is close to the actual turbine power value then the efficiency is large and vice versa.

Abstract

This study aims to analyze and design an effective Solar Power Plant (PLTS) in Sambas Regency using the spatial data-based Weighted Overlay method. Sambas Regency, located in the 3T (Disadvantaged, Frontier, Outermost) area and directly bordering Malaysia, faces the challenges of uneven electricity distribution and the growth of energy demand that continues to increase along with population growth. With significant renewable energy potential in West Kalimantan, especially solar energy reaching 20 GW, this research has high relevance in providing sustainable solutions to support the region's energy needs. A GIS-based Weighted Overlay approach is used to determine the optimal location of PLTS by considering various parameters such as NDVI, NDBI, NDMI, LST, Slope, Rainfall, distance to PLN substation, and existing PLTS location points. The results of this mapping and analysis were then integrated into the technical design of the PLTS using PVSyst software. This research successfully overcomes practical obstacles, such as land protected by the Ministry of Environment and Forestry, by providing detailed solutions that can be implemented. With the continuous growth of energy demand in Sambas Regency, the implementation of utility-scale solar power plants is becoming increasingly urgent. Through economic analysis that includes NPV, PI, IRR, and DPP, this investment can be concluded as feasible. With the application of the right methodology, it is hoped that this research will make a real contribution in supporting Indonesia's efforts to achieve carbon-neutral targets and meet energy needs in border areas that are still unelectrified.

Abstract

Lemukutan Island is an island administratively located in Bengkayang Regency, West Kalimantan province. Currently, electrical energy on Lemukutan Island is supplied by 1 unit of Diesel Power Plant (PLTD) which has an installed capacity of 140 kW, but PLTD only operates 14 hours/day, from 16.00 to 06.00 WIB. One of the efforts to be able to provide 24-hour electricity services on Lemukutan Island can be done by operating PLTD for 24 hours and alternative efforts by utilizing hybrid Solar Power Plants (PLTS). In a hybrid system between PLTD and PLTS, researchers calculate the capacity of solar panels, calculate the number of batteries, calculate the number of solar charge contoller, and calculate the capacity of the inverter to be used. The economic analysis used only calculates the initial investment cost and OM costs. Based on the calculation of solar panels used as many as 1473 units with a capacity of 550 Wp, the total watt-peak power is 810 kWp, batteries with a total energy of 2418.9 kWh, Solar Charge Controller using 207 units and 7 inverter units. In the calculation of the total initial investment costs incurred amounted to Rp.10,122,917,594 and investment cost of Rp. 12,497,429/kWp if the installation cost is 0.6%. OM costs amounted to Rp.101,229,175 while the operational and maintenance costs that must be incurred in accordance with the age of the PLTS project that is run following the life of solar panels for 25 years amounted to Rp. 1,760,485,107.

Abstract

This research employs Optisystem for evaluating network quality through calculation and simulation. It includes direct observation of installed devices at Perum 4 East Pontianak and network simulations using parameters like Power Link Budget, Rise Time Budget, BER, and Q factor. Calculations indicate that power levels on the downstream and upstream sides meet the standard. RTB analysis and BER and Q factor simulations confirm compliance with PT Panglima Kamayo Media and ITU-T G.984 standards. However, a design-implementation mismatch affects two consumers with significant power deviations, necessitating network improvements. PLB and RTB calculations on both sides confirm compliance with standards, and simulations validate the furthest network's feasibility. Yet, two specific consumers, 24 and 27, require improvements due to Prx power exceeding limits. These enhancements should consider internal and external factors, such as anthill interference. Overall, Perum 4 East Pontianak's FTTH network meets standards with potential improvements for uniformity, offering valuable guidance for PT Panglima Kamayo Media in enhancing consumer services.
