Abstract

Sumber energi untuk pembangkit listrik yang berasal dari fosil semakin menipis membuat manusia harus mencari sumber energi alternatif. Salah satu sumber energi listrik alternatif tersebut adalah air. Pembangkit listrik yang menggunakan air sebagai sumber utamanya dan menghasilkan energi di bawah 1 MW disebut PLTMH. Dengan besar debit rata-rata mencapai 9,18 m3/s dan head yang terukur mencapai 4,9 m. Sungai Ciliman di Kabupaten Pandeglang merupakan salah satu sungai yang mempunyai potensi energi yang cukup besar. Menggunakan turbin jenis propeler, potensi awal yang dapat dihitung mencapai 357 kW. Hasil simulasi menggunakan software Turbnpro, total produksi energi pertahun yang dihasilkan adalah sebesar 2679,64 MWH.

Abstract

In this research will optimize the loading system of power plant units 1-4 of PLTU Suralaya using genetic algorithm method. Optimization (unit of commitment) is designed using matlab software with the right purpose and constraints. Unit Commitment is a problem in the work system that determines the timing of the plant to meet the electricity needs. The method used is a system that can produce optimal loading system with a minimum cost. The simulation was conducted on 1-4 units of Suralaya power plant with total load of 33,117 MW for 24 hours. Using genetic algorithm, the cost reduction process is 5.7105%.

Abstract

Gangguan listrik tiga fasa ke tanah merupakan salah satu faktor yang menyebabkan permasalahan kualitas daya. Salah satu gangguan kualitas daya listrik yang sering dijumpai ialah voltage sag. Pada praktiknya, gangguan kualitas daya tidak dapat dihindari. Tujuan dari penelitian ini ialah mengetahui fungsi kompensasi pada unified power quality conditioner (UPQC). UPQC memiliki kontroler yang dapat mengatur media penyimpanan energi DC untuk mengkompensasi tegangan sistem yang turun. Kontroler yang digunakan didasari oleh teori dq0. Hasil dari simulasi menunjukkan tegangan sebesar 66,2% dapat dikompensasi UPQC menjadi 100,4% pada sistem 380 V. Kinerja UPQC cukup bisa diandalkan karena alat ini dapat mengkompensasi tegangan saat terjadi gangguan. Kata kunci: Kualitas daya, voltage sag, UPQC, sistem distribusi

Abstract

Transformer is the most widely used electromagnetic induction equipment in the electrical system. When the transformer is connected to a voltage source it will happen an undesirable phenomenon that is inrush current. The incidence of inrush current in the transformer can reduce the life of the transformer because large currents will enhance the performance of the transformer. One method to reduce inrush current is to use pre-insertion resistor method. This research uses pre-insertion resistor method which is a method with insert resistor on the primary side of transformer with time 0.18 second. The resistor used in the pre-insertion resistor method serves as a current buffer when the process of energizing the transformer. This research uses Matlab Rb2014a software to know the inrush current of transformer. The result of the transformer simulation test using pre-insertion resistor method, the inrush current is reduced by 29% for the 710 kW motor load capacity, with the motor load capacity of 1420 kW reduced inrush current of 30%. Furthermore, with a load capacity of 2130 kW motor, the inrush current is reduced by 28% and for the motor load capacity 3550 kW reduces the current by 27%.

Abstract

The stability of the electric power system is very important, because the stability of the system affects the quality and reliability of electrical energy supply. Many things can affect the stability of the system, one of which is a dynamic load that affects dynamic stability, dynamic stability can be defined as the system's ability to remain in synchronous conditions after the first swing (transient period) until the system reaches steady state condition, a power system is said to be in stable when all variables are stable, both bus voltage, rotor angle and generator rotor rotational speed. In this study the authors used the automatic voltage regulator (AVR) and power system stabilizer (PSS) controls to control the system's dynamic stability, hoping that after installation of these additional control devices the dynamic stability of the power system could be improved so that the system remained stable despite disturbances or load changes . Then a power system simulation was carried out using the MATLAB 2008a program, which proved that the installation of a power system stabilizer can reduce oscillation, in this case PSS works as an electric power controller or reactive power can be seen from the output voltage which only has overshoot 1.0169 before a load change and after being given a load change with the input step 25 overshoot increasing only 1.0215 for output the speed and angle of the generator rotor is less influential.
