Determination and statistical treatment of short-circuit currents for faults on the lines of networks of 440 kV CESP system
(1995-12-01)
The distribution of short-circuit current is investigated by means of two methods, one direct and the other analytic; both methods consider uniform probability distribution of line faults. In the direct method, the procedure ...

Identification of Fractional-Order Transfer Functions Using a Step Excitation
(2015-09-01)
This brief proposes a new method for the identification of fractional-order transfer functions based on the time response resulting from a single step excitation. The proposed method is applied to the identification of a ...
An inductor-free realization of the Chua`s circuit based on electronic analogy
(SPRINGER, 2009)
Although literature presents several alternatives, an approach based on the electronic analogy was still not considered for the implementation of an inductor-free realization of the double scroll Chua`s circuit. This paper ...
Chaotic communication based on the particle-in-a-box electronic circuit
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
A secure communication system based on the error-feedback synchronization of the electronic model of the particle-in-a-box system is proposed. This circuit allows a robust and simple electronic emulation of the mechanical ...
Allocation of protective devices in distribution circuits using nonlinear programming models and genetic algorithms
(Elsevier B.V., 2004-04-01)
The optimized allocation of protective devices in strategic points of the circuit improves the quality of the energy supply and the system reliability index. This paper presents a nonlinear integer programming (NLIP) model ...
