The recent ban on conventional incandescent lamps for residential use led Brazilian consumers to choose from three main lighting technologies: incandescent halogen, CFL (Compact Fluorescent Lamp), and LED (Light Emitting Diode). Despite the fact that their electrical performances are well known,...

This paper proposes a reduced 2nd, 3rd, 5th and 7th harmonic current of all power supply units and ac drives which effects of heating neutral cables and transformer. The commercial or automation building require the operation of many parallel-connected switch mode power supply and ac drive on...

The recent ban on conventional incandescent lamps for residential use led Brazilian consumers to choose from three main lighting technologies: incandescent halogen, CFL (Compact Fluorescent Lamp), and LED (Light Emitting Diode). Despite the fact that their electrical performances are well known,...

Nowadays, grid-connected photovoltaic (PV) systems constitute an emerging technology. This has given rise to concerns about their contribution to harmonic distortion levels in utility grids. Valuable insight into the electrical behavior of such a system, including its impact on power quality,...

The wind farm generators are new energies sources in the Algerian electrical networks, as every project their placements are determined by the wind assets of the site suitability (economic evaluation), its proximity to the power grid of which it will be connected (technical assessments). The...

This paper is deals with the implementation of a software control method for harmonic content evaluation in the dq synchronous rotating reference frame for grid side VSIs (Voltage Source Inverters) used in DPGS (distributed power generation systems) applications. In order to verify the...

An evolutionary computation approach for optimization of power factor and power output of wind turbines is discussed. Data-mining algorithms capture the relationships among the power output, power factor, and controllable and non-controllable variables of a 1.5MW wind turbine. An evolutionary...

Electrical arc furnaces are commonly employed in industry to produce molten steel by melting iron and scrap steel. Furnace control is a necessary operation for production optimization. The principal parameters to be controlled are: maximum productivity requirements, minimum power off time, good...

This paper describes a doubly fed induction generator (DFIG) control for wind energy generation. The DFIG model is established and the adopted control strategies for machine side and grid side converters are described. Flicker phenomenon is defined and its emission of variable speed wind turbine...

This paper presents the design and implementation of an instantaneous current control technique for a three-phase shunt hybrid power filter (SHPF) to compensate harmonics generated by non-linear loads. The control of the SHPF is based on synchronous reference frame (SFR) method. The SHPF...
