Design and Performance Analysis for Welding Fumes Extraction System 1

Abstract During Welding operation, the fumes and metallic gases are emitted from the work piece, which cause the pollution and hazard to workers, when gases were inhaled or ingested. This usually cause respiratory effects such as lung disease, bronchitis and possible of lung cancer. This paper deals with the designing of fume extraction system and evaluate the performance such as efficiency of the system, filtration capacity, and environmental friendly, during the welding proces...

A New Voltage Stability Index For Predicting Voltage Collapse In Electrical Power System Networks

ABSTRACTPower system voltage instability often results in voltage collapse and/or system blackoutwhich is a source of concern for power network operators and consumers. This workproposes a new line stability index that is suitable for investigating the voltage stabilitycondition of Power System Networks (PSNs). This index, which is called the New LineStability Index-1 (NLSI_1), is derived from first principles and shown to incorporate theLine Stability Index (Lmn) and the Fast Voltage S...

Development Of Nonlinear Control Schemes For Electric Power System Stabilization

ABSTRACTPower system stabilizers and other controllers are employed to damp oscillations inpower systems, thereby guaranteeing satisfactory dynamic performance following majornetwork disturbances. However, the parameters of these controllers are often tuned basedon the power system linearized model which generally is a function of the systemoperating point or state. These controllers suffer from poor performance when the systemstate changes. The aim of the research work reported in thi...
