Abstract

In Convertion process to be AC voltage and current, often happens some faults as harmonics. Harmonics effect in Electrical Power System is big enough causes overheated to equipment that has lower impedance. The propose of the research is to design and simulate an inverter to get minumum harmonics distortion values less than 5% as stated in Total Harmonics Distortion (THD). In this case, one phase fullbridge inverter performance uses Selective Harmonics Elimation (SHE) Method and Sinusoidal Pulse Width Modulation (SPWM) Method. SHE is used to eliminate ordinal harmonics carried by SPWM Inverter. SPWM only eliminates high ordinal harmonics therefore SHE is needed to eliminate lower ordinal harmonics. Determination of switching angle is solved by Newton Raphson Iteration Method. SPWM and SHE are analyzed based on simulation using MATLAB/SIMULINK 2016a software. SHEPWM inverter is equipped with LC filter to produce sinusoidal waveform output. The result of SHEPWM with LC filter design in single phase inverter produces 222 VAC ouput voltage and 0,28% of THD. Keywords : Inverter, Newton Raphson, SHE, SPWM, THD

Abstract

Energi surya sangat murah untuk didapatkan, tetapi besarnya berfluktuasi setiap saat dan berbeda di setiap wilayah. Pemanfaatan potensi energi terbarukan ini dalam menghasilkan energi listrik diprioritaskan untuk daerah terisolasi atau ditempatkan pada sistem distribusi (generator terdistribusi) yang secara langsung melayani kebutuhan beban. Durasi pembangkit listrik tenaga surya dalam menyediakan energi listrik di grid adalah tidak tetap dan berubah setiap saat. Hal ini disebabkan oleh perubahan potensi cuaca (radiasi matahari) dan pemilihan teknologi yang diterapkan. Ketersediaan sistem generator dengan pola operasi PLTS yang berdiri sendiri diperoleh 44,3% untuk area Panam dan 28,6% untuk area Sudirman. Secara keseluruhan, ketersediaan rata-rata sistem pembangkit tenaga surya (PLTS) untuk kota Pekanbaru adalah 36,45%.

Abstract

South Bekasap Area PT. Chevron Pacivic Indonesia was an area that has flash density reach at 1,970 flash/km2/year with IKL level at 136 thunder days per year. The amount of lightning current that strikes phase wires can be minimized by using a ground wire. this is done by adjusting the angle between the ground wire to phase wire to form a region that free from lightning strikes called protected region. In the analysis of protected region, first we must determined the level of lightning protective system needs base on standart that used in Indonesia, called SNI-03-7015-2004. From the analysis of hazard assesment, it was found the level of lightning protection needs at level I with striking distance at 20 meter. Based on data and analysis, then it is known that the distribution line 13,8 kV So.Bekasap has level protection system that is less good. In protective angle method calculations, the single poles (type A, B, and C) have protection region at 33o and double poles (type SAA, SBB, and SCC) at 26o. While based on rolling sphere method, the single poles (type A, B, and C) have protection region at 13o and double poles with double ground wires (type SAA, SBB, and SCC) at 27o.Keywords: protected region, protection system, protective angle method, rolling sphere method.

Abstract

The distribution system is an important part of the electrical energy distribution activities as directly connected to the customers. Therefore, the distribution system is always required to have good reliability. One way to increase reliability is using recloser. Optimal placement of recloser will be able to maximize reliability. The author used a genetic algorithm method in determining the optimal position of recloser. Objective function is combining SAIFI and SAIDI. SAIFI and SAIDI are calculated using section technique method. Simulation calculations using MATLAB (Matrix Laboratory) programming. Testing program conducted on radial distribution network. The result is recloser position within 0.157 km from existing recloser. Reduction of SAIFI after the addition of recloser is 13.23%. While the reduction of SAIDI is 2.57%.Keywords : reliability, genetic algorithm, recloser

Abstract

This paper describes the design and simulation of a dc-dc buck-boost converter using the buck-boost coupled inductor topology to equalize the dc input voltage source to the load voltage with a wide voltage conversion range. The buck-boost converter coupled inductor system with a closed circuit that is controlled by PI control, voltage mode control, and current mode control on the PWM (Pulse Width Modulation). This circuit is simulated using the PSIM software, and the outputs are analyzed then compared to a buck-boost converter that does not use a coupled inductor. It is indicated that the buck-boost converter without coupled inductor has an input voltage width in the range of 4-21 Volt result in the output voltage of 14 Volt, while a converter using a coupled inductor has an input voltage width in the range of 3-64 Volt, and it generates the steady output voltage of 14 Volt. Key Words: buck and boost converter, coupled inductor, PWM, voltage-mode control, current-mode control, PI control.

Abstract

The transformer is widely used, both in the field of electricity and electronics. Use of the power system allows choosing the appropriate voltage and economical for each purposes. To obtain a good and satisfying design it is necessary to use computer software in design process. The design of single phase and three phase transformer with the help of computer software is intended to replace the conventional process which is done manually so as to improve the efficiency of time and energy. In this research, we use visual basic 6.0 as a program language and the golden ratio (1 : 1,618) is used as the ratio between the width and thickness of the iron coreKeywords: Transformer, Visual Basic 6.0, Golden Ratio

Abstract

One of the significant purposes of reliability system analyzing is to evaluate the system’s ability to complete the load system requirement. The real problems of assessing the adequacy of the generation and bulk power transmission system about providing a dependable and suitable supply at the terminal stations can be designated as composite system reliability evaluation. The electric power system of Pekanbaru is an isolated system consisting of 4 generations, 12 substations, and 22 transmission lines. The calculated reliability evaluation by using expected energy not supplied indices at each substation in the contingency N-1. The outage of the generation unit significantly affects the EENS value in the hybrid system, the amount of capacity that comes out of the system greatly affects the value of the load that can be served. There is no EENS value when the contingency N-1 of the transmission line is due to the ring system model and the radial system as well as the large current-carrying capacity of the transmission line, so that when a contingency N-1 occurs the transmission line system can still serve all load points. The results of this study show that the EENS value existed at the release of the PLTU tenayan 1 and PLTU Tenayan 2. The EENS value is 2347,5415 MWh/ year or 0.054% of the total energy consumption in 2019 at the Garuda Sakti substation.Keywords: composite reliability, contingency, load curtailment, EENS, ETAP 12.6.
