A tunable triode-MOSFET transconductor and its application to g(m)-C filters
(Iscas '99: Proceedings of the 1999 IEEE International Symposium on Circuits and Systems, Vol 2, 1999-01-01) [Trabalho apresentado em evento]
A linear, tunable CMOS transconductance stage is introduced. Drain voltage of the input transistor operating in triode region is settled by a regulation loop and a first-order linear relationship between g(m) and a de bias ...
Reliability evaluation of distribution systems considering automatic reclosers
(2004 International Conference on Probabilistic Methods Applied to Power Systems, 2004-12-01) [Trabalho apresentado em evento]
This paper presents a new methodology to evaluate in a predictive way the reliability of distribution systems, considering the impact of automatic recloser switches. The developed algorithm is based on state enumeration ...
Synchronous machines parameters identification using load rejection test data
(IEEE International Electric Machines and Drives Conference Record, IEMDC, 1997-01-01) [Trabalho apresentado em evento]
This work shows a computational methodology for the determination of synchronous machines parameters using load rejection test data. The quadrature axis parameters are obtained with a rejection under an arbitrary reference, ...
Network reconfiguration of distribution systems using metaheuristics and reliability measures
(2009 15th International Conference on Intelligent System Applications to Power Systems, ISAP '09, 2009-12-09) [Trabalho apresentado em evento]
In an evermore competitive environment, power distribution companies need to continuously monitor and improve the reliability indices of their systems. The network reconfiguration (NR) of a distribution system is a technique ...
