Harmonic estimation is essential for mitigating or suppressing harmonic distortions in power systems. The most important idea that spectrum analysis, waveform estimation, source classification, location, the determination of contributions, data clustering, and filter-based elimination capacity are also considered. feature extraction method a fundamental component optimization improves effective...

Nowadays, light emitting diode (LED) lamps have been widely utilized for lighting system due to its low-energy consumption. The harmonic emission standard is ignored by most of the manufacturers, high current will increase injection and cause fire risk. Existing research focuses on investigating emissions from several specific LED drivers, but a systematic evaluation approach not given. contrib...

Harmonics in power distribution system are current or voltage that are integer multiples of fundamental frequency. For example if the fundamental frequency 50 Hz, then the 2-nd harmonics is 100Hz, the 3-rd is 150Hz, etc. A pure voltage or current sine wave has no distortion and no harmonics but non sinusoidal wave has distortion and harmonics. To quantify the distortion, the term total harmonic...

In this manuscript, the author has tried to analyze a study of Variable Frequency Drives. Variable frequency drives are energy saving drives. But they generate harmonics generates. Harmonics introduced by any means affect the performance parameters of any system The presence of harmonics is the system for a long duration & that, too, of higher order affect the various parameters in a Power dist...

Computer Applications in Power System is place an important role to verify the system performance and real time monitoring systems. Most of the Electrical system uses LABVIEW and other software to monitor real time electrical transition. In this paper we are focusing on Power Electronic Conversion system. Power Electronic System is easily simulated using MATLAB Software. Here we are giving easy...

This paper presents a multi-objective control strategy for power quality issues. With increasing applications of nonlinear and semi-conductor devices in distribution systems and industries, power-quality (PQ) problems, such as harmonics, neutral current elimination, voltage sag, voltage swell reactive power has become an unavoidable issue. Due to the changing trends and restructuring of power s...

The topology and control of three-phase 4-wire DSTATCOM consisting of a operating flexibility in the DSTATCOM consisting of a operating flexibly in the voltage or current control mode. In the voltage control DSTATCOM topology includes three single-phase voltage source converters connected in parallel. The proposed DSTATCOM provides the voltage regulation of power factor correction along with ha...

In distribution system (DS), the majority of power consumption has been drawn in reactive loads. These loads are drawn in low power factor and therefore give rise to reactive power burden in the distribution system. So that DSTATCOM controller is used to compensate reactive power, correction of power factor and elimination of current harmonics. This paper presence the 7-Level Cascaded Hbridge I...
