Voltage Stability Enhancement Based on Optimal Allocation of Shunt Compensation Devices Using Lightning attachment procedure optimization
This paper proposes a combined approach to determine the optimal allocation of different shunt compensation devices (shunt capacitor, static var compensator, and static synchronous compensator) in power systems. The developed ...
CMOS SHUNT REGULATOR WITH BANDGAP REFERENCE FOR AUTOMOTIVE ENVIRONMENT
(Iee-inst Elec EngHertfordInglaterra, 1994)
Aplicação do shunt piezoelétrico para controle passivo de chatter no processo de torneamento da liga Ti-6Al-4V ELI
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Mecânica - PPGEMecCâmpus São Carlos, 2022-08-01)
One of the main limitations for increasing the productivity of machining processes is the emergence of self-excited vibrations. This type of phenomenon, commonly called chatter, arises due to the interaction of the cutting ...
Shunt quenching and concept of independent global shunt in multijunction solar cells
(IEEE Electron Devices Society, 2018-07)
We show that two-terminal multijunction cells interconnected by tunnel junctions are fairly immune to individual local shunts, thanks to the shunt quenching. Interestingly, they may still suffer from global shunts. We ...
Sizing and location of shunt FACTS devices in power system using genetic algorithms
(UniandesMaestría en Ingeniería EléctricaFacultad de IngenieríaDepartamento de Ingeniería Eléctrica y Electrónica, 2011)
FACTS (Flexible AC Transmission Systems) devices are used to improve different problems in a power system. In this work, a Genetic Algorithm (GA) is used to solve a multi-objective optimization problem which consists of ...
Voltage stability analysis taking into account a shunt connected device based on power electronics
(Universidad Nacional de Colombia Sede Medellín, 2011)
In this paper the power system voltage stability problem is analyzed with active power–voltage (PV) curves, as a voltage compensator is introduced. The PV curves’ shape has been a subject of great concern, especially when ...
Needle guided ab interno technique for tube insertion through the ciliary sulcus in uncontrolled glaucoma
(SAGE Publications, 2022)
Purpose: To describe a modified ab interno technique for the tube implantation from a glaucoma draining device into the ciliary sulcus. Materials and methods: The modified ab interno technique was performed on four eyes ...
Effect of parametric uncertainties on the performance of a piezoelectric energy harvesting device
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2012)
The use of piezoelectric materials for the development of electromechanical devices for the harvesting or scavenging of ambient vibrations has been extensively studied over the last decade. The energy conversion from ...
