Abstract

Industry is one of the economic sectors that plays a role in processing environmental resources into products with higher utility values. This process includes design activities, industrial engineering, and service provision. Matra Abadi Workshop, a manufacturing industry that in its operations produces harmonic currents in the electric power system network, especially in low-order harmonics such as 3rd, 5th, 7th, 9th, and 11th. To reduce the negative impact of harmonics on the power system, the use of passive harmonic filters is required. Among the types of filters used, single tuned filters are a common choice because of their simple construction and effectiveness in reducing certain order harmonics that exceed the IEEE 512–2014 standard limits. This study discusses the implementation of both types of filters in a manufacturing industry environment. The harmonic reduction process is carried out through filter design and testing using Matlab/Simulink software-based simulations. The simulation results show that after the application of passive filters, the harmonic current levels in all load configurations were successfully suppressed to within the IEEE 512–2014 standard limits. The reduction in Total Harmonic Distortion (THDi) after the application of the single tuned filter was recorded in the range of 17.86% to 11.06%. In addition, there was an increase in the power factor from 0.68 before the filter was installed to 0.91 after the installation, which indicates an improvement in the overall power system performance.

Abstract

The wood processing industry heavily relies on three-phase induction motors to drive high-power equipment such as chipper machines. One of the major challenges in operating these motors is the high inrush current during startup, which can destabilize the power system and accelerate equipment wear. This study aims to analyze the effectiveness of using a soft starter as a starting method for a 400kW induction motor in a chipper application. The research method is an experimental case study involving direct field observation and theoretical calculations of electrical parameters such as nominal current, current limiting, torque, and trip class. The observation results show that the actual starting current of 1,216.15 A remains below the calculated current limiting threshold of 1,575 A, while the trip class value of 2,835 A provides optimal protection. The use of a soft starter proves effective in reducing inrush current, maintaining voltage stability, and enhancing the reliability and efficiency of motor operation. This research supports the application of soft starters as a suitable solution for high-power motor starting in heavy industrial settings.
