Abstract

This research is the design of an On-Grid Solar Power Plant (PLTS), at the Faculty of Engineering building of Universitas Kristen Indonesia (FT UKI). In analysing this design, both from the technical and economic sides and determining the Break Event Point (BEP), the HOMER application tool is used. The research method used is quantitative method, which includes collecting, analysing and presenting data in the form of numbers. After doing the HOMER simulation. PLTS consists of 407 solar panels with a total overall power capacity of 150,890 Wp (watt peak), as well as 16 units of inverters with a total overall capacity of 160,000 kW (kilowatt), and the total cost of all components is Rp. 1,245,305,649.95. In terms of economics, the cost savings from the Net Present Cost (NPC) value of this design is Rp. 830,000,000, saving the Levelised Cost of Electricity (LCOE) cost of Rp. 227.87/kWh (kilowatt hour), and saving Operation & Maintenance (O&M) costs of Rp. 142,000,000. From the results of this study, a BEP value of around 7.27 years was obtained.

Abstract

This paper presents the results of research on a 290 Wp (Watt-peak) Off-Grid Solar Power Plant (PLTS) at the Faculty of Engineering Building, Universitas Kristen Indonesia - Jakarta, aiming to investigate current harmonics on the load side and reduce the Total Harmonic Distortion (THDi) value using a single-tuned LC passive filter. Based on the measured current per order, calculations were conducted, revealing that the THDi on the load side (LED) amounted to 16,42%. The dominant harmonic currents were the 3rd order with a THDi of 5,7% and the 10th order with a THDi of 15,3%. According to the simulation results using MATLAB Simulink, the single-tuned LC passive filter was capable of reducing the THDi level on the LED from 16,42% to 1,81%.

Abstract

Beban listrik nonlinier menyebabkan timbulnya distorsi harmonik, faktor daya rendah, dan harmonik arus dan tegangan pada beban listrik residensial. Studi ini meneliti kualitas daya listrik residensial. Studi ini mencakup faktor daya, THD, TDD, arus dan tegangan harmonik. Berdasarkan hasil pengukuran, diperoleh THDv sebesar 1,91%, masih dalam batas 8% IEEE-519 2022. Juga diperoleh, dominan THDi orde ke-5 sebesar 7,7% dan THDi orde ke-3 sebesar 6,6%, yang melebihi batas 4% standar IEEE-519 2022. Juga, diperoleh nilai TDD sebesar 10,7%, yang lebih tinggi dari batas standar 5%. Dari hasil simulasi, diperoleh nilai TDD 3,586 %, masih dalam batas standar 5%, dan THDi orde ke-5 sebesar 1,990 % dan THDi orde ke-3 sebesar 2,946%, yang memenuhi batas 4% standar. Berdasarkan nilai THDv dan nilai TDD hasil pengukuran, maka diperoleh faktor daya sebenarnya 0,822. Namun, setelah simulasi, terjadi kenaikan faktor daya sebenarnya menjadi 0,921. Hasil penelitian menunjukkan bahwa intervensi melalui simulasi mampu menurunkan distorsi harmonik arus hingga memenuhi standar IEEE-519 2022 sekaligus meningkatkan efisiensi faktor daya sistem.
