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 formulation for the substation grounding design
(Elsevier, 1999)[Abstract] A Boundary Element approach for the numerical computation of substation grounding systems is presented. In this general formulation, several widespread intuitive methods (such as Average Potential Method) can ... -
A fully discrete BEM-FEM method for an exterior elasticity system in the plane
(Elsevier BV * North-Holland, 2001)[Abstract] We present a modified version of the usual BEM–FEM coupling for the exterior elasticity problem in the plane (cf. Costabel and Stephan, SIAM J. Numer. Anal. 27 (1990) 1212–1226). This new formulation allows us ... -
A numerical approach based on the BEM for computing transferred earth potentials in grounding analysis
(2003)[Abstract] In this paper we present a numerical approach based on the Boundary Element Method for the analysis of a very common problem in electrical engineering practice: the existence of transferred earth potentials in ... -
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 ... -
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 ... -
¿Son fiables los métodos convencionales para el cálculo de redes de puesta a tierra?
(2004)[Resumen] Para diseñar una toma de tierra es preciso calcular su resistencia equivalente y la distribución de potencial en la superficie del terreno durante una derivación de corriente [1, 2, 3]. Para elllo las normas sólo ... -
Why do computer methods for grounding analysis produce anomalous results?
(IEEE Power Engineering Society, 2003)[Abstract] Grounding systems are designed to guarantee personal security, protection of equipments and continuity of power supply. Hence, engineers must compute the equivalent resistance of the system and the potential ...
