Research ArticleOpen accessIn the abstractElectric Power System Under-Voltage Load Shedding Protection Can Become a TrapLuiz Augusto Pereira Fernandes, Alexandre Rocco, Heraldo Silveira Barbuy, Geraldo Caixeta GuimarãesProblem statement: Under-Voltage Load Shedding (UVLS) protection of Electric Power Systems (EPS) is frequently used against Voltage Collapse (VC), however when there is automatic bus voltage regulation with excessive capacitive compensation, the UVLS scheme may not trip. In this case, load shedding must be based in a Voltage Collapse Proximity Indicator (VCPI). Many UVLS procedures may not be appropriate today. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,203 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Emissions from Power Stations on the Ambient Air Quality of Selected Urban Areas in KuwaitBader N. Al-Azmi, V. Nassehi, A.R. KhanIn Kuwait, two main power stations, one comprising of seven-300MW steam generators at Doha and other with eight-300MW steam generators at Subyia cover the major power requirement of Kuwait city.

Research ArticleOpen accessIn the abstractControl Strategy for Discontinuous Conduction Mode Boost Rectifier with Low Total Harmonic Distortion and Improved Dynamic ResponseH.S. AthabDue to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harmonics. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,418 accessesView PDFCite
