Research on corona discharges from plasma generators has been studied using the line-plane configurations (L-PC). The purpose of this study is to calculate the comparison of the level of conformity of the voltage current characteristic curve (I–V) from the simulation results of numerical calculations of the electrode geometry function and the results of experimental data. There is an electrode (electrode 1) in the form of a rectangular plate with a very thin thickness which has a length and width of a and b respectively in an upright position (line configuration). Electrode 1 has a distance of c to electrode 2 which is in a lying position (plane configuration) below the electrode 1. Furthermore, by using variation of c of 2.5 cm, 2.8 cm, 3.1 cm and 3.4 cm, the two electrodes are connected to the plasma generating equipment, thus producing a plasma discharge that comes out of the tip of the electrode 1 towards electrode 2. Research results from all variations of c prove that there is a high degree of suitability between numerical calculations with experimental data by taking the value of the fitting for the sharpness shape factor of k in the area with the largest plasma discharge.

Highlights• This paper focuses on the (I-V) characteristics calculations of the corona discharge.• The numerical calculation approach uses the concept of the electrode geometry model. • There is an accuracy high degree between the numerical calculations and the research data.

The calculation of the electrode model in the corona plasma discharge case has been carried out using the semi-ellipse line to plane (S-ELTP) configuration model in the air. The final focus of this research is to calculate the (I–V) current–voltage characteristics of the plasmas discharge. Part of the work in the (I–V) characteristics includes computational calculations and carrying out experimental activities. Experimental data include current vs voltage variations that occur at the time of plasma discharge. All the discharge processes are generated by a positive DC voltage source. The arrangement of the geometric configuration of the electrodes consists of two plates in the form of a half ellipse (active electrode) and a rectangular plate (passive electrode) in a mutually perpendicular position. The size variation of the active electrode includes variations of the small and large size plates with each plate having two variations in the distance between the two electrodes. The calculation concept of the electrode model is to insert the certain shape sharpness factor of k in the numerical calculation in the sharp electrode capacitance part. The k factor value is obtained by calculating the fitting between numerical simulation and research data. The research results prove that there is a fairly high level of conformity between numerical simulation and the research data. Simulation calculation for the (I–V) characteristic curve and its level of accuracy used Python GUI Programming.

Penyediaan energi baru dan terbarukan yang lebih ramah terhadap lingkungan akhir-akhir ini lebih mengemuka tidak hanya karena energi fosil yang semakin menipis tapi sebagai bentuk tanggung jawab terhadap energi berkelanjutan. Namun pada tataran pelaksanaan meski pemerintah melalui KEN dan RUEN telah memberikan pedoman sejauh ini belum berjalan baik. Lebih khusus terhadap pemanfaatan energi surya yang secara ironis yang berpotensi terbesar justru pemanfaatannya paling sedikit. Makalah ini memberikan studi awal pada ide skema pemanfaatan energi surya melalui Photovoltaic (PV) atap yang terkoneksi jaringan on-grid tanpa penyimpanan energi sebagai pembangkitan terdistribusi Distributed Generation dengan memanfaatkan jaringan lisrik yang telah terkoneksi luas. Metode ini memanfaatkan keunggulan jumlah pelanggan yang sangat besar dan dengan memanfaatkan sebarannya yang luas dengan program pembiayaan nasional yang berbeda dengan penggunaan PLTS terpusat berskala besar.
