Abstract

This paper discusses the improvement of dielectric strength of dielectric coconut oil using olive oil to be used as an alternative to liquid insulation on high voltage equipments. Increasing the breakdown voltage level has been done by adding olive oil of 5% -25% into coconut oil. Heating was considered to reduce the water content in coconut oil. Electrical testing (using breakdown voltage test), physical testing (by testing the water content using oven method), and analysis of the acid content of simple saturated fat using mixing formula, have been performed to determine the feasibility of coconut oil as insulation agent. The test results indicated the breakdown voltage of a pure coconut oil value of 23.47kV / 2.5mm, which did not fulfilled the IEC 156 standard, which is 30kV/2.5mm. The addition of olive oil could increase the breakdown voltage level to 38.73 kV / 2.5 mm and if the heating can reach 51.15kV/2.5mm. The highest breakdown volatge level of 54.01kV/ 2.5mm could be obtained by mixing the olive oil and heating the coconut oil at once. ell. It can be concluded that the addition of olive oil could decrease the saturated fatty acid content from 91% to 72.2%, whereas the heating could reduce the water content from 2697 ppm to 361 ppm. From the point of view of water content, the modified coconut oil could not meet the maximum permitted standard JIS 2320, which is 50 ppm. Based on the achieved breakdown voltage level, the considered coconut oil will be able to work on electrical equipment with a working voltage level of 0.75 kV-13.2 kV.

Abstract

AbstractThis study discusses the improvement of the power factor in the Glenmore Sugar Industry electrical system. Low power factor can be caused by variations in inductive loads. This has an impact on large currents and high reactive power so that a black out can occur in the Glenmore Sugar Industry electrical system. Low power factor is corrected with the most effective Costum Power Devices, namely Static Var Compensator (SVC) and Static Synchronous Compensator (STATCOM). The evaluated and corrected load buses are those with low power factor.The simulation results show in the application of SVC for the lowest results, power factor increased from 0.76 to 0.78 with reactive power values in the range from + 1.6 to – 0.64 MVAR. The power factor increased from 0.76 to 0.85 with reactive power values in the range from +4.9 to –1.9 MVAR. And for the highest results, the power factor increased from 0.82 to 0.92 with reactive power values in the range from +3.9 to –1.5 MVAR.The application of STATCOM can increase the power factor with reactive power values in the range from +4.9 to – 0.994 MVAR, +1.6 to -0.32 MVAR and +3.9 to -0.7875 MVAR. Keywords – Power factor, SVC, STATCOM, Reactive power, Industry.

Abstract

Abstrak – Pemanfaatan energi listrik sebagai upaya menciptakan green energy memerlukan suatu tindakan yang mendukung produksi energi yang efisien dengan menggunakan satu atau lebih energi alternatif yang dapat digabungkan menjadi sumber energi terdistribusi. Permasalahan pokok permintaan sumber energi yang semakin meningkat adalah keandalan sistem dan kualitas daya. Kualitas daya berkaitan dengan pengurangan nilai rugi-rugi daya listrik, berkurangnya nilai jatuh tegangan serta kontinuitas penyaluran energi listrik yang baik. Penambahan distributed generation (DG) pada sistem eksisting dinilai mampu mengurangi permasalahan kualitas daya dan meningkatkan keandalan sistem. Penelitian ini membahas optimasi penempatan DG dengan menggunakan metode Cat Swarm Optimization dan Krill Herd Algorithm. Optimasi dilakukan dengan menginjeksi DG pada sistem eksisting. Dari proses optimasi dengan CSO diperoleh penurunan rugi daya sebesar 0,2 % sedangkan dengan KHA diperoleh penurunan 29,5 %. Perbaikan profil tegangan dengan metode KHA dinilai lebih baik dari CSO dengan nilai diatas 0,99 p.u sedangkan CSO 0,96 p.u. Penelitian ini mengindikasikan bahwa metode KHA lebih baik daripada metode CSO.Kata Kunci — Distributed Generation, Cat Swarm Optimization, Krill Herd Algorithm.

Along with the development of technology, a lot of research is carried out to improve the efficiency of voltage regulators. One of the efforts to improve this efficiency is to modify the converter part on the voltage regulator. In this journal will be discussed about the Forward-Flyback Autotransformer converter (AFF) used as voltage regulator. The reason for using autotransformer in this simulation is because the efficiency of autotransformer is higher when compared to ordinary transformers. AFF converter simulation is done by providing variations in the form of duty cycle and also resistive load. This simulation is done to prove the comparison between theory and simulation as well as prove the efficiency of AFF converter is higher when compared to ordinary transformers. After the test, the highest AFF converter efficiency was achieved at 99.06% when the duty cycle value was 0.6.Keywords: AFF Converter, Duty Cycle, Resistive Load.

Abstract

The transmission line that functions to distribute energy from the generating center to the load center must function efficiently. However, the extensive network allows the line operation to be inefficient. This allows the occurrence of power losses and voltage drop in the system. Therefore, efforts are needed to effectively utilize the available power system capacity, one of which is by installing new devices such as TCSC (Thyristor Controlled Series Capacitor). The method used is the Sensitivity Index. Power flow analysis using PSAT (Power System Analysis Toolbox) program. Based on the data analysis that has been done, it was found that the most sensitive line is Pngkep70kV–Mndai. After the installation of the TCSC device on the sensitive line, there was a decrease in power losses and an increase in voltage stability in the system compared to before the installation of TCSC. Thus it can be concluded that the installation of TCSC provides a positive performance on the electricity system of South and West Sulawesi.

Abstract

Road, as one of the land transportation infrastructure, is important for economic improvement of an area. It needs special and regular maintenance by the local government, in order to keep the road in good condition. For this purpose, the government conducts a survey with the aim of getting criteria for determining priority of road maintenance. The obstacle in implementation of road maintenance is the lack of criterias which make difficulties in determining the priority of road maintenance. Decision-making system is needed to solve the problems of determining the priority of road maintenance. Fuzzy Analytical Network Process (FANP) can solve the problem by calculating the criteria to get priority value. This method consists of many steps, namely weighting among criteria, weighting among sub-criteria, triangular fuzzy number, fuzzy synthesis, weight matrix, and priorities. The results show that the priority order of routine road maintenance is Jl. Jakarta, Jl. Kelud, and Jl. Kyai Tamin. The accuracy rate obtained in this research is 66.67%. Sensitivity test shows that the damage of the roads and the road density are important factors in generating the weight value road maintenance priorities.

Abstract

The transportations have important role in facilitating population mobility, one of the transportations are the train. In order to decrease mass, speed up the movement, and decrease carbon emission, electrification has been done, so that electrical train was created. Three-phase induction motor is chosen as a mover because of its sturdiness, lack of brush and commutator, and also shock wave. Three-phase induction motor works using induction principle therefore the excitation can be obtained from stator induction to rotor. One of the most important parameters on the transportations is braking. Regenerative braking becomes an excellent option since it can obtain energy from braking process, it converts kinetic energy to electrical energy, in that case the motor act as a generator. It can occur when the slip is negative. Negative slip can be obtained when the synchronous speed is under the rotor speed. The testing to analyze capacitors capacitance for motor excitation is needed before applying to the real condition. The test has been done in two steps, there are noload test and loaded test using dc to dc converter and battery. The result from Simulink MATLAB 2022a simulation shows that the bigger capacitors capacitance, the lower regeneration frequency produced, so that the synchronous speed will be lower, then negative slip will be bigger that can inflict bigger braking torqueand bigger regeneration voltage. Keywords–– Capacitor Capacitance, Rotor Rotating Speed, Regeneration Voltage, Regenerative Braking, Synchronous Speed, Three-Phase Induction Motor, Torque
