Abstract

Coal Boiler Plant at PT. Salim Ivomas Pratama is a plant for making steam, almost all activities in the cooking oil and margarine production process utilize electrical energy, such as submersible and centrifugal electric motors with controllers, computers, AC inverters, and many others which include non-linear loads. Electrical load whose correlation between voltage and current is unbalanced, this non-linear load will result in harmonic disturbances in the electric power system which causes a reduction in the service life of electrical equipment. Harmonics are defined as voltage and current frequency distortions that are not sinusoidal from pure frequencies. This study aims to determine how effective the active filter design simulated with the PSIM Software is in reducing harmonics with a non-linear load of 3 VSD connected to a 55 kW, 0.37 kW, and 7.5 kW induction motor. The results of measurements and analysis show that there are harmonics on the panel. SDP with a current harmonic value for phase R of 26.6%, phase S of 27.5%, and phase T of 25.5%, when compared with standard harmonics, all phases exceed the standard SPLN with a standard value of 20%. Then it is necessary to reduce harmonics with an active filter, after designing andsimulating it in the PSIM software the simulation results show that the current harmonics have changed for phase R by 3.3%, phase S by 4.0%, and phase T by 3,4 %. This shows that the design of the active filter is quite effective in mitigation a harmonic, to then be applied in practice at PT. Salim Ivomas Pratama in reduction the harmonics in a coal boiler plant.

Abstract

Based on PLN standards regulated in Minister of Energy and Mineral Resources Regulation No. 20 of 2020, changes in voltage on the network must be maintained within the voltage variation range of ±5% (Normal Voltage). Voltage is the change in voltage variations in a short time. Where the voltage change exceeds or below the standard voltage variation range, namely ±5% of the normal voltage. Based on IEEE Standard 1159-1995, the sag voltage is in the range of 10% -90% of the nominal voltage which lasts for 0.5 cycles. The voltage wave is in the range of 120% of the nominal voltage. Changes in voltage variations are caused by many factors such as large motor starting currents, uncontrolled load changes and short circuit current disturbances in the electric power system. The importance of maintaining voltage is a necessity because it is related to the reliability of an electric power system. For this reason, this research proposes "Application of the Fast Fourier Transform Method to Monitor Voltage Fluctuations" as a solution to power quality problems. To make it easier to process voltage (sinusoidal), the Fast Fourier Transform (FFT) method is needed. The FFT method algorithm is needed to convert the time domain into the frequency domain, so that it can simplify the monitoring system process. This research was implemented the FFT method for monitoring voltage fluctuations in no-load and load conditions. From the results, it can be concluded that inductive loads can affect voltage quality. This was proven when carrying out tests under load, from the results of the analysis there was a decrease in voltage (voltage SAG) of 10% (Vrms = 209.5 V; time duration 0.1436 s) and an increase in voltage (voltage swell) of 20.6% ( Vrms = 278.75 V; time duration 0.228 – 0.428 s).

Abstract

In the current test, leaks really need to be carried out at GIS Simpang. This test was carried out by strengthening the 20 kV incoming cable in the GIS Simpang 150/20 kV transformer bay. The impact of measuring this leakage current is to reduce the occurrence of leakage currents so that they are not too severe because this can determine how much the leakage current increases in the incoming cable. The trend test results were measured to determine the comparison between the leakage current in January and the leakage current measurement process at GIS Simpang. Based on the results of leakage current testing on transformer 1 and transformer 2 incoming 20 kV cables from several phases, it shows that the results of the leakage current trend in the cables have not increased significantly. However, from the calculation results listed, it can be seen from the comparison table that the results have increased during the calculation and have slight differences compared to the leakage current measurement results themselves. This is because from the calculation results, the cable temperature detection experienced a slight increase in the cable temperature as measured by thermovision to determine the thermal failure voltage. However, the cable is still suitable for operation because the temperature of the cable itself has a standard that does not exceed 150C for several measured cable phases.

Abstract

The transmission system distributes electricity from power plants to substations before reaching consumers. During this process, obstacles such as power loss and voltage regulation occur, which must meet specific standards to prevent equipment damage. Power loss can result from factors like corona effects and insulator leakage. This study aims to analyze power loss and voltage regulation based on daily peak load data at 14:00 over 15 days, recording current and voltage values on the extra-high voltage Krian-Grati transmission network. This system uses ACSR Gannet conductors with a cross-sectional area of 392.84 mm² and a length of 79.41 km, having a resistance of 0.00086 Ω/km. Manual calculations for short transmission lines show a voltage difference between sending and receiving ends, with the sending voltage being slightly higher due to reactance, preventing a drastic voltage drop. Over 15 days in December 2024, voltage regulation did not exceed the standard maximum of <10%, with the highest recorded value at 4.7%. The highest power loss occurred on day 7 at 0.089 MW, while the lowest was on day 9 at 0.023 MW. The total power loss over 15 days reached 1.024 MW, with a daily average of 0.068 MW.

Abstract

Sajen Village is predominantly an agricultural and livestock-based community. However, the lack of sufficient electricity poses a significant challenge to the development of these sectors. Solar Power Generation Technology offers a sustainable solution due to the village’s potential for utilizing solar energy. To ensure the successful implementation of solar power plant, it is essential to provide the local community with adequate knowledge and skills in its operation, maintenance, and care. This community service program aims to introduce solar power plant to the residents of Sajen Village while equipping them with the necessary technical expertise. The program consists of several key activities: training on solar power plant operation and maintenance, an introduction to the principles of solar power plant design and installation, and evaluation sessions to assess the community's understanding. These activities are designed to empower participants to independently operate and maintain solar power plant systems. The final stage involves evaluating the program’s effectiveness by measuring the participants’ comprehension of solar power plant concepts, operations, and maintenance techniques. This initiative is expected to enhance the sustainability of Sajen Village's agricultural and livestock sectors by addressing the electricity shortage through renewable energy solutions. It also promotes community independence in managing solar power systems for long-term benefits
