Abstract
The electrical power system is an essential part of a factory, providing the necessary electrical flow for production. Electrical disturbances need to be minimized, including harmonic disturbances which are often overlooked. These disturbances arise from non-linear loads such as inverters that cause harmonic distortion and imperfect waveforms. The aim of this research is to identify and analyze how to reduce these harmonics. The research begins with observing harmonic disturbances occurring at PT. Indo Acidatama, followed by a literature review to understand how previous researchers addressed harmonic distortion. Next, a design is created using ETAP, the design results are tested for compliance with applicable standards, and the process concludes with the writing of a report. The design and analysis results show that in the single line diagram of the distribution system at PT. Indo Acidatama, harmonic distortion causes the THDv and THDi values in the distribution system to not comply with IEEE 519 and SNI 7029:2004 standards, where THDv and THDi values must be below 5%. From the analysis of the distribution system, non-linear loads such as VFDs cause high harmonic distortion at three buses: lamp pump (THDv 5,53%, THDi 2,49%), SDP power spray dryer (THDv 5,52%, THDi 2,49%), and vipump (THDv 5,52%, THDi 2,62%). Non-linear loads also cause high power losses, namely 16,2 kW and 40,0 kVAR. The installation of a high pass damped filter on the SDP power spray dryer bus, which is a source of distortion due to VFD, can reduce harmonic distortion at order 17. After installing the filter, the harmonic distortion values decreased: lamp pump bus (THDv 2,60%, THDi 1,44%), SDP power spray dryer bus (THDv 2,60%, THDi 1,52%), and vipump bus (THDv 2,60%, THDi 1,52%). Power losses also decreased to 15,4 kW and 32,0 kVAR.
