Abstract

The grounding system design of the 150 kV substation have resolve affect in lightning strike area. The purpose of this study is to determine the duration of the potential difference penetration that occurs due to direct or indirect lightning strikes. The parameter method grounding system uses a combination of  R and L for the grid section and a combination of RLC for the rod section. Simulations due to direct lightning strikes in nearby areas greatly affect the spike in the amount of potential difference. The potential difference in the area closest to the lightning strike with a maximum surge of 57.42 V with a neutralization duration of 0.21 μs. At the furthest distance from a lightning strike, the maximum potential difference spike is only 3.14 V with a neutralization duration of 2 μs. The average duration of neutralization due to lightning strikes is 2 μs. In the simulation of a direct lightning strike striking electrical equipment, it causes a very high potential difference spike in lightning strike area of ​​992.96 V with a spike duration of 0.012 μs. The farthest area point at the location of the lightning strike has a spike of 31.07 V with a spike duration of 0.06 μs. The duration of neutralization at a potential difference below 1 V, has a duration of more than 2 μs depending on the distance from the location of lightning strike. The grounding system design is able to perform good performance with a fast potential difference neutralization duration in the event of a direct or indirect lightning strike. Lightning strikes that occur will not cause dangerous step and touch voltages for personnel in the 150 kV substation area.

Abstract

The need for electrical energy continues to increase over time. However, in Indonesia power plants are still dominated by fossil fuel power plants, and there are still many areas without access to electricity. The use of renewable energy is needed to replace fossil fuels considering that fossil fuels can run out one day. The coastal area of Batakan Village in Tanah Laut Regency, South Kalimantan Province, was chosen as the focus location for conducting hybrid power plant simulations because this village is located in a coastal area where wind and solar energy sources are abundant. Batakan Village is approximately 40 km from Pelaihari City. Medium-voltage network transmission system (JTM) is supplied from Pelaihari City, and it is almost certain that this village experiences large power losses over long distance. This power loss will be detrimental if an effort is not made to reduce it. The purpose of this research is first to determine the optimal hybrid power plant configuration design to reduce power loss in the electricity system in Batakan Village. Second, it will analyze the power loss of the hybrid power plant system in Batakan Village, and finally, this research is going to analyze the investment feasibility of the hybrid power plant system in Batakan Village. In this study, the design of renewable energy plants, such as solar power plants (PLTS) with a total capacity of 406.1 kW and wind power plants (PLTB) with a total capacity of 125 kW, and the electricity network (grid system) are used together in a hybrid power generation system. The ETAP software was used to analyze the power losses of the hybrid power generation system, while the HOMER software was used to determine the net present value (NPV) and cost of energy (COE) of the hybrid power generation system. The results show that the configuration of the solar, wind, and grid systems is the most optimal. It is obtained from the results of ETAP simulations that have been carried out during average load and peak load conditions that by including the Solar Power Plant and Wind Power Plant power losses in the electricity system in Batakan Village can be reduced from the previous one using the system configuration only connected to the PLN power grid (grid system only). The total power losses incurred was 269.1 kW of active power and 1613.5 kvar of reactive power at average load reduced to 266.9 kW of active power and 1568.9 kvar of reactive power. At peak load the total power losses were 423.4 kW of active power and 2573.0 kvar of reactive power and they deceased to 41.,5 kW of active power and 2510.5 kvar of reactive power. In terms of investment, the COE value decreased by IDR 111, and the NPC decreased by IDR 6,600,000,000 at the average load. At the peak load COE decreased by IDR 88, while NPC by IDR 7,000,000,000. The return of investment (ROI) value is 13.2%, which indicates that the investment is still in the profitable stage.

Abstract

Impedansi menara transmisi menjadi parameter yang harus dipertimbangkan sebelum pembangunan jaringan transmisi. Terbatasnya alat ukur menjadi kendala melakukan pengukuran langsung terhadap menara transmisi secara utuh. Dengan merancang rangkaian ekivalen menara yang akan diukur, pengukuran dapat dilakukan dengan mengukur resistansi dan reaktansi sampel material menara terlebih dahulu. Peralatan pembanding pengukuran parameter pasif resistansi dan reaktansi merupakan suatu sistem yang disusun dari beberapa komponen dan alat ukur yang dirangkai. Rangkaian ini terdiri dari rangkaian pengaman inrush, autotransformator variabel, dan beberapa komponen penyusun lain. Dengan menginjeksi suatu material menara transmisi 150 kV akan menjadi langkah awal dalam mengetahui resistansi dan induktansi. Material yang diinjeksi akan dihubungkan dengan osiloskop menggunakan probe tegangan dan probe arus untuk kemudian diamati perbedaan waktu antara gelombang tegangan dan gelombang arus, dihitung sudut fasenya, dan dihitung resistansi serta induktansinya. Dengan adanya mekanisme peralatan ini akan menjadi pembanding bagi alat ukur LCR meter. Dengan rancangan yang lebih mudah dirakit dan mudah dijumpai di lapangan, ini akan menjadi alternatif apabila LCR meter tidak tersedia.

Abstract

ABSTRAKBiaya utilitas adalah salah satu komponen terbesar dalam biaya produksi sebuah pabrik farmasi. Dari total biaya utilitas, 63% berasal dari pemakaian energi listrik. Jika energi listrik tersebut dapat diperoleh dari Energi Baru Terbarukan (EBT) hingga 10.65%, maka akan berdampak positif bagi biaya produksi. EBT yang dapat dipakai adalah Pembangkit Listrik Tenaga Surya (PLTS) dengan memanfaatkan atap gedung produksi. Selain penghematan perlu diperhatikan dampak interkoneksi PLTS terhadap arah aliran daya, kestabilan sistem kelistrikan saat gangguan, dan potensi terhadap sambaran petir ke instalasi PLTS. Optimalisasi desain PLTS dengan Helioscope menunjukkan kapasitas PLTS yang dapat dipasang hingga 1,1 MWp. Hasil analisis aliran daya dengan ETAP menunjukkan bahwa daya reaktif yang mengalir balik ke jaringan PLN sangat kecil. Sistem kelistrikan dengan injeksi daya dari PLTS ini dapat stabil setelah mengalami gangguan. Berdasarkan metode sudut perlindungan maka untuk 9 bangunan yang dipasang PLTS tersebut diperlukan proteksi petir level IV.Kata kunci: energi surya, kestabilan sistem tenaga, aliran daya, perlindungan sambaran petir ABSTRACTUtility costs are one of the largest components in the production expenses of a pharmaceutical plant.
