Abstract

Solar energy is a source of energy that will never run out and has almost no negative effects on the environment. In this study using Pvsyst software with Stand Alone/Off Grid PV System conditions. Bagan Deli is one of the kelurahan in Medan Belawan sub-district which is located in a coastal area to analyze the potential for solar energy which is located at latitude 3.7756° north longitude, longitude 98.7033° east longitude. The optimal tilt angle according to the latitude is 10° (Tilt Angle) and the Azimuth angle of 180° (Azimuth Angle) facing south. The PV module used in the simulation is a solar cell module selected from the PVsyst database, namely Si-mono TDB 156X 156-36P 150W. The electricity load per day is 2,625 kWh/day, the need for electricity supply in one year is 958.1 kWh. Through the PVsyst software simulation, the Stand-Alone Solar Panel System uses 4 solar panels with a power of 150Wp, an area of ​​4 m2 and 2 batteries with a capacity of 200 Ah which are installed in series. The results of the performance of the Stand-Alone Solar Panel System obtained unused Energy of 0.2 kWh/kWp/day, Loss on PV Array of 1.12 kWh/kWp/day, Loss on PLTS System of 0.28 kWh/kWp/day, Energy that supplied to the user at 3.05 kWh/kWp/day.

Abstract

Distribution transformer is one of the most important components in the electric power distribution system. Distribution transformers often experience load imbalance problems. One previous study showed that load imbalance can reach 25.6% which contributes to increased power losses. This study aims to analyze the relationship between the percentage of load imbalance and the power losses incurred at PT. PLN (Persero) ULP East Binjai. This study was conducted with a quantitative approach by calculating the percentage of load imbalance and the resulting power losses. Data were collected through direct observation, voltage and current measurements, then calculations and analysis were carried out. The results showed that a greater percentage of load imbalance occurred at night at 12.96% while during the day at 10.03%. And the resulting power losses occurred at night at 853.3 Watts while during the day at 4,386.3 Watts. Thus, it can be concluded that the greater the percentage of load imbalance, the greater the power losses incurred.

Abstract

This paper analyzes the efficiency performance of a 7.5 kW three-phase induction motor controlled by a Variable Speed ​​Drive (VSD) for industrial speed regulation applications. The motor is rated at 380 V, 50 Hz, four poles, with a nominal speed of 1440 rpm. A constant voltage-to-frequency (V/f) control strategy is implemented with operating frequencies varying from 30 Hz to 50 Hz. Simulation-based analysis is conducted to evaluate electrical input power, mechanical output power, rotational speed, torque, and efficiency under different operating conditions. The results show that the motor input power decreases from approximately 8.0 kW at 50 Hz to 4.0 kW at 30 Hz, indicating significant energy-saving potential during partial-speed operation. Motor efficiency increases with frequency, ranging from 80.0% at 30 Hz to a maximum of 88.8% at the rated frequency. The reduced efficiency at lower frequencies is mainly attributed to the dominance of constant losses such as core and mechanical losses. The study confirms that VSD-based speed control improves operational flexibility and enhances energy efficiency of three-phase induction motors, making it suitable for industrial applications with variable load and speed requirements.

Abstract

This study discusses the analysis of the electrical system at the MDN302 Mabar Gudang Site, which is used to support the operation of telecommunications equipment. The electricity supply at the site comes from a three-phase PLN network with a voltage of 380/220 V, but the installed operational loads use a single-phase system (phase–neutral). The study was conducted through field surveys, electrical parameter measurements, and technical calculation analysis to evaluate the performance of the electrical distribution system. The analysis includes power calculations, system current, distribution cable voltage drop, MCB capacity selection, and evaluation of the grounding and lightning protection systems. Voltage drop calculations were performed using a single-phase system approach with copper conductors and international units (SI). The calculation results show that the voltage drop value on all distribution lines is below the maximum limit of 5% according to the 2011 PUIL standard. The grounding resistance value obtained of 0.5 Ω also indicates that the grounding system has met safety requirements. In addition to technical aspects, this study also presents a Bill of Quantities (BoQ) as part of the electrical system material planning. The selection of MCB capacity and relatively large cable sizes was carried out as a long-term planning strategy to anticipate future load increases. Based on the analysis results, the electrical system at Site MDN302 Mabar Gudang was declared safe, reliable, and feasible for operation.
