Viscosity Of Hydrocarbon Liquids Saturated With Gas
( Qatar University , 1995 , Article)Experimentally measured kinematic viscosities are reported for benzene, cyclohexane and n-heptane saturated with hydrogen, nitrogen and carbon dioxide. A Zeitfuchs cross-arm viscometer suspended in a unique design ... -
The Voltage Collapse Problem Based On The Power System Loadability
( Qatar University , 1997 , Article)This paper addresses the problem of voltage instability at which the power system reaches its maximum admissible load. A voltage collapse proximity indicator (VCPI) is derived and its performance is investigated. The VCPI ... -
Voltage Stability Margin Identification Using Local Measurements And Linear Kalman Filter
( Qatar University , 2002 , Article)Voltage stability investigation is of a great importance for long-term electric load expansion as well as power system operation. This paper presents a new algorithm for identification of voltage instability in a specified ...
