RANCANG BANGUN FILTER PASIF UNTUK MEREDUKSI TOTAL HARMONIC DISTORTION (THD) AKIBAT PEMAKAIAN LAMPU HEMAT ENERGI (LHE) DAN LIGHT EMITTING DIODE (LED)

Lektrokom : Jurnal Ilmiah Teknik Elektro, 2021
This paper discusses the design of a passive filter system for energy saving in Energy Saving Lamps (LHE) and Light Emitting Diode (LED), but for LHE and LED lamps for current Total Harmonic Distortion (THDi) that do not meet the standard. To reduce the current THD, it can be done by installing a single tune passive filter.””In this paper, we discuss ...

Power quality enhancement using active power filter five-level cascade H-bridge under unbalanced and distorted grid

Electrical engineering & Electromechanics, 2023
Introduction. To improve the power quality of a supply system, the total harmonic distortion (THD) is the most important parameter in the quantification of harmonics caused by nonlinear loads. In practice, it must be less than 5 %.

SIMULASI PENGGUNAAN FILTER AKTIF SHUNT DENGAN KONTROL PI UNTUK MEREDAM TOTAL HARMONIC DISTORTION (THD) PADA GEDUNG DH TEKNIK ELEKTRO UNIVERSITAS UDAYANA

Jurnal SPEKTRUM, 2023
Every daily activity requires electrical energy. Electrical energy loads vary. Harmonic distortion is one of the results of current and voltage wave disturbances caused by non-linear loads, such as lamps, computers, and air conditioners, among others. This causes a decrease in the quality of electric power.

Design of a Three‐Phase PWM Rectifier Based on Improved Whale Optimization Algorithm Optimized Fuzzy Control

Advanced Control for Applications, Volume 8, Issue 3, September 2026.
Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

Analisis Total Harmonic Distortion (THD) dan Arus Harmonik Akibat Penggunaan Lampu Hemat Energi (LHE) dan Light-Emitting Diode (LED) secara Kolektif Pada Jaringan Tegangan Rendah

Jurnal Fokus Elektroda : Energi Listrik, Telekomunikasi, Komputer, Elektronika dan Kendali), 2021
Currently, people are increasingly using energy saving lamp (LHE) and LED because of their energy saving and low power consumption. But the use of LHE and LED in large quantities can reduce the quality of electric power. This is because LHE and LED are classified as non-linear loads which are a source of harmonic distortion for low-voltage power lines.

Design and Simulation of a Carrier PWM‐Based Capacitor to Support a Dynamic Voltage Restorer for Voltage Swell and Voltage Mitigation in the Distribution System

Engineering Reports, Volume 8, Issue 7, July 2026.
This study designs and simulates a capacitor‐supported dynamic voltage restorer (DVR) using Carrier PWM control to mitigate voltage sags, swells, and distortions in three‐phase distribution systems. The self‐supported DVR employs a DC‐link capacitor as an energy buffer, eliminating external storage needs. Control via Synchronous Reference Frame Theory (
