Cálculo y diseño asistido por ordenador de tomas de tierra en instalaciones eléctricas: una formulación numérica basada en el método integral de elementos de contorno
(1995)
[Resumen] En esta tesis doctoral se presenta una formulación numérica general para el
cálculo y el diseño asistido por ordenador de tomas de tierra en
instalaciones eléctricas. En primer lugar, se identifica la naturaleza ...
A numerical refraction-diffraction model in the ray-front coordinate system
(Computational mechanics: new trends and applications (CD-ROM), 1998)
[Resument] A model for the propagation of water waves is presented, which retrieves the
concepts of rays and fronts from the geometrical optics approximation. Their definition here
is nevertheless different in that it ...
Una formulación general de elementos de contorno para el diseño asistido por ordenador de tomas de tierra en subestaciones eléctricas
(Centro Internacional de Métodos Numéricos en Ingeniería, CIMNE (Barcelona), 1996)
[Resumen] La puesta a tierra de una instalación eléctrica es imprescindible para
garantizar su seguridad cuando tienen lugar situaciones de fallo. Para su correcto
diseño se requiere la determinación de una serie de ...
A BEM approach for grounding grid computation
(Computational Mechanics Publications, 1994)
[Abstract] Grounding systems are designed to preserve human safety and grant
the integrity of equipments under fault conditions. To achieve these goals,
the equivalent electrical resistance of the system must be low ...
A BEM formulation for computational design of grounding systems in stratified soils
(Centro Internacional de Métodos Numéricos en Ingeniería, 1998)
[Abstract] Substation grounding design involves computing the equivalent resistance of the earthing system -for reasons of equipment protection-, as well as distribution of
potentials on the earth surface -for reasons of ...
A boundary element numerical approach for earthing grid computation
(Elsevier, 1999)
[Abstract] Analysis and design of substation earthing involves computing the equivalent resistance of grounding systems, as well as distribution of potentials on the earth
surface due to fault currents [1,2]. While very ...
Desarrollo de una formulación numérica basada en el MEF para la estabilización de problemas de transporte por convección-difusión
(Sociedad Española de Métodos Numéricos en Ingeniería, 1999)
[Resumen] La modelización de problemas en mecánica de fluidos cuando la velocidad del fluido es elevada resulta complicada debido a la aparición de inestabilidades en la solución numérica al emplear esquemas convencionales ...
Development of a CAD system based on a BEM approach for earthing grids in stratified soils
(Elsevier, 1999)
[Abstract] The design of safe earthing systems is esential to assure the security of the persons as well as the protection of the equipment and the continuity of the power supply. For the attainment of these aims, it is ...
Analytical integration techniques for earthing grid computation by boundary element methods
(Centro Internacional de Métodos Numéricos en Ingeniería, CIMNE (Barcelona), 1992)
[Abstract] Analysis and design of substation earthing involves computing the equivalent resistance of grounding systems, but also distribution of potentials on the earth surface due to fault currents [1]. While very crude ...
A validation of the boundary element method for grounding grid design and computation
(Centro Internacional de Métodos Numéricos en Ingeniería, CIMNE (Barcelona), 1992)
[Abstract] Several widespread intuitive techniques developed during the last two decades for substation grounding analysis, such as the Average Potential Method
(APM), have been recently identified as particular cases of ...
