Laboratorial Tests with Transmission Line Model Based on Modified pi Circuits
(Ieee, 2017-01-01)
One way to model the transmission lines is applying cascades of pi circuits for representing these systems. In practice, it is impossible to carry out tests in actual lines responsible for transmitting large blocks of ...
Influence of Damping Resistance in Electromagnetic Transients Using Alternate Structures of pi Circuits
(Ieee, 2017-01-01)
For modeling the transmission lines with lumped elements, it is necessary to use a large amount of 7 circuits in cascade. However, using this type of model, numerical simulations are affected by numerical errors that cause ...
Alternative Model of Three-Phase Transmission Line Theory-Based Modal Decomposition
(Institute of Electrical and Electronics Engineers (IEEE), 2012-09-01)
In this paper is shown the development of a transmission line, based on discrete circuit elements that provide responses directly in the time domain and phase. This model is valid for ideally transposed rows represent the ...

PI Stabilization of a Class of Time Delay Systems
(2003-11-07)
In this paper we use the Hermite-Biehler theorem to establish results for the design of proportional plus integral (PI) controllers for a class of time delay systems. We extend results of the polynomial case to quasipolynomials ...

Integration Methods Used in Numerical Simulations of Electromagnetic Transients
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01)
This paper made an analysis of some numerical integration methods that can be used in electromagnetic transient simulations. Among the existing methods, we analyzed the trapezoidal integration method (or Heun formula), ...
