Analisis Penggunaan Filter Damped untuk Mereduksi Total Harmonic Distortion (THD) di Rumah Sakit Umum Daerah (RSUD) Klungkung

Majalah Ilmiah Teknologi Elektro, 2018
Pengoperasian beban non linier merupakan penyebab timbulnya harmonisa. Tingkat distorsi atau disebut Total Harmonic Distortion (THD) yang tinggi berpotensi menurunkan kualitas energi listrik yang disalurkan. Dalam penelitian ini dilakukan pengukuran THD pada tiap Sub Distribution Panel (SDP) di RSUD Klungkung.

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 ...

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.

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.

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 %.

A 3-to-5 V Input, 80 Peak-to-Peak Voltage (Vpp) Output, 2.75% Total Harmonic Distortion Plus Noise (THD+N), 2.9 μF Load Piezoelectric Actuator Driver with Four-Switch Buck–Boost

Actuators, 2023
As human–computer interaction has become increasingly popular, haptic technology has become a research topic of great interest, since vibration perception, as a type of haptic feedback, can enhance user experience during an interaction. However, the high power consumption of existing drivers makes them unsuitable for use in portable devices.

Determination of Total Harmonic Distortion (THD) on a 33kv Distribution Network: A Case Study of Island Business District

Nigerian Journal of Technology, 2015
Modern day AC power systems are proliferated by the introduction of several kinds of nonlinear loads which generate harmonics in a power system and this has a cumulative negative effect on power quality. Examples of nonlinear loads are power electronic devices, which cause distortion of voltage and current waveforms and consequently create a number of ...

A New Multicarrier Sinusoidal Pulse Width Modulation (SPWM) Strategy based on Rooted Tree Optimization (RTO) Algorithm for Reducing Total Harmonic Distortion (THD) of Switched-Capacitor Nine-level Inverter in Grid-connected PV systems

Indonesian Journal of Science and Technology, 2021
This paper proposed a new strategy of sinusoidal pulse width modulation (SPWM) technique to control three-phase nine-level switched-capacitor inverter (9LSCI) in grid-connected PV systems. The main advantage of this inverter is high voltage gain, achieved by switching the capacitors in series and parallel to boost up the output voltage using low ...
