The influence of harmonics from non-linear loads in the measuring transformers of electrical substations
(2006-04-01)
The mainstreams of research papers developed to analysis of electrical systems power quality for non-linear loads are conducted for low voltage feed. This, if in one hand have furnished important results about the performance ...
Non-linear modal analysis for beams subjected to axial loads: Analytical and finite-element solutions
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A rigorous derivation of non-linear equations governing the dynamics of an axially loaded beam is given with a clear focus to develop robust low-dimensional models. Two important loading scenarios were considered, where a ...
A Time-domain Harmonic Power-Flow Analysis in Electrical Energy Distribution Networks, Using Norton Models for Non-linear Loading
(Ieee, 2014-01-01)
The purpose of this paper is to present the application of a three-phase harmonic propagation analysis time-domain tool, using the Norton model to approach the modeling of non-linear loads, making the harmonics currents ...
A set of linear equations to calculate the steady-state operation of an electrical distribution system
(2011-12-19)
In this paper, the calculation of the steady-state operation of a radial/meshed electrical distribution system (EDS) through solving a system of linear equations (non-iterative load flow) is presented. The constant power ...

On an Optimal Linear Control Applied to a Non-Ideal Load Transportation System, Modeled with Periodic Coefficients
(Trans Tech Publications Ltd, 2011-01-01)
In this paper, a load transportation system in platforms or suspended by cables is considered. It is a monorail device and is modelled as an inverted pendulum built on a car driven by a DC motor. The governing equations ...

Non-linear 3D finite element analysis of full-arch implant-supported fixed dentures
(Elsevier B.V., 2014-05-01)
Despite the necessity for faster clinical protocols for immediate loading of implant-supported dentures, there is a lack of biomechanical studies to confirm the rigid splinting effectiveness. We compared the stress in ...
