EXPERIMENTAL CHARACTERIZATION OF COMPACT FLUORESCENT LAMPS FOR HARMONIC ANALYSIS OF POWER DISTRIBUTION SYSTEMS

Experimental characterization of compact fluorescent lamps for harmonic analysis of power distribution systems

The modeling of a compact fluorescent lamp for harmonic analysis under terminal voltage variation is presented in this paper.The compact fluorescent lamp is represented Handheld Vacuum Wheel with the diode bridge rectifier model, which is commonly used for harmonic analysis.The set of parameters is estimated for different values of the terminal vol

Long-term agricultural land-cover change and potential for cropland expansion in the former Virgin Lands area of Kazakhstan

During the Soviet Virgin Lands Campaign, approximately 23 million hectares (Mha) of Eurasian steppe grassland were converted into cropland in Northern Kazakhstan from 1954 to 1963.As a result Kazakhstan became an important breadbasket of the former Soviet Union.However, the collapse of the Soviet Union in 1991 triggered widespread agricultural aban
