Wide-band switches and true-time delay (TTD) phase shifters have been developed using distributed microelectromechanical system (MEMS) transmission lines for applications in phased-array and communication systems. The design consists of a coplanar waveguide (CPW) transmission line (W = G = 100 m) fabricated on a 500m quartz substrate with fixed–fixed beam MEMS bridge capacitors placed periodica...

Controller Area Network operational characteristic supports periodic, sporadic and event based task behavior of distributed embedded system for industrial applications. CAN connect distributed Electronics Control Units (ECU) serially in the network and share measured data of different parameters and control information from the different places. System reliability and redundancy can be affected...

This paper deals with the shunt compensation design of long 380kV-50Hz XLPE cables by simulating a double-circuit partially cabled connection with the transmission length of 80 km in the Dutch transmission system. The proposed procedure for shunt compensation sizing is fully elaborated in this paper. Four sizing criteria are used to find the minimum required size of compensation. All simulation...

-This paper presents an algorithm for locating faults on two-terminal power transmission lines. Unsynchronized twoend voltages and currents are processed in the algorithm for determining the distance to fault and the synchronization angle. The calculations are performed initially for the lumped model of the transmission line. Then, these results are used as the initial data for the Newton-Raphs...

This paper presents the modeling of highly nonlinearcircuits using a total-variation-decreasing (TVD) differencescheme developed for the simulation of problems involving shockphenomena. In contrast to the commonly used leapfrog scheme,a second-order accurate TVD method based on the Lax–Wen-droff scheme is applied to one-dimensional nonlinear transientelectromagnetic-wave...

In this paper a transformerless Static Synchronous Series Compensator (SSSC) to increase the power capacity of a 230 kV transmission line is proposed. In order to eliminate the transformer, a 15-level cascade H Bridge (CHB) inverter is employed within the proposed compensator structure to inject reactive power to the transmission line. The theory of instantaneous p-q power using in the compensa...

We call piezoelectromechanical (PEM) truss beam a truss modular beam coupled with a transmission electrical line when the coupling is obtained by piezoelectric actuators which act as bars in the module and as capacitances in the electrical line. The truss module length is assumed negligible with respect to the considered wave lengths. The transmission electrical line is assumed continuously dis...

In this paper, waveforms of collided digital signal bits are analyzed by superposition of step responses of a distributed constant circuit for a transmission line. Our analysis indicates narrow voltage spike on the leading edge of bit pulses in collided waveforms. The width and peak of the spike calculated by our analysis were matched with those of experiments. Since the spike might cause signa...
