This research presents a discrete-time transmission line model based on the propagation of travelling waves. In this approach, the transmission line is emulated by means of many interconnected elementary delay cells implemented with switched-capacitor (SC) circuits. The accuracy and limitations of this method is compared to existing transconductance-capacitor (gm-C) solutions and is evaluated in the...
This paper presents constraints involved in the microelectronic implementation of a transmission line model based on transconductor-capacitor (gm-C) topologies. The presented line model, based on the discretization of a transmission line into a finite number of series inductors and shunt capacitors, is aimed for the fault location in power network, a technique using the Electromagnetic Time-Reversal...
This paper examines the use of the symmetrical components theory for the representation of unbalanced conditions, when using the concept of analog emulation for highspeed power system analysis. This concept has been proven and validated through the realization of a mixed-signal hardware platform dedicated to power system studies. Computations related to the grid are handled by analog electronics,...
This paper explores the potential and limitations of analog integrated circuit techniques for the simulation of low-loss or lossless 1D or 2D transmission mediums. In this approach, a transmission line is mapped into a ladder consisting of N identical LC elements, each modeling a finite length increment of the line. Inductors are then emulated by a gyrator-capacitor combination, yielding a classical...
This paper presents the extension of a platform originally devoted to symmetrical transient stability analysis, into the domain of unbalanced faults. The aim of this solver is to increase the speed of dynamic stability assessment for power systems. It is based on an analog representation of the grid alongside dedicated digital resources for the simulation of the models of power network components...
