Electromagnetic Interference Prediction in Transient Electromagnetic Environment

2007 International Symposium on Electromagnetic Compatibility, 2007
This paper presents an approach to predict the interference effects of a transient electromagnetic environment (EME) caused by an aggregate of wideband transmitters on a traditional narrowband victim. Due to the constraint of the narrowband receiver, it is sufficient to evaluate such wideband parameters of transmitter as effective isotropically ...

Quantum Electromagnetic Transients Program

IEEE Transactions on Power Systems, 2021
This letter devises a quantum electromagnetic transients program (QEMTP) which is the first attempt to tackle the computational challenges in solving EMTP through quantum computing. The main contributions lie in: (1) A quantum-enabled EMTP formulation with Dommel's model encoded in quantum states; 2) An Harrow-Hassidim-Lloyd (HHL)-based QEMTP to solve ...

An Efficient Solver for Electromagnetic Transient Simulation

2019
In this paper a mesh-free method for electromagnetic transient simulation is presented. This method enables to simulate electromagnetic problems avoiding the use of a regular grid in the discretized model. The proposed method is a particular mesh-free method based on particles, that is no initial regular grid but only an arbitrary particles ...

Imaging And Inversion Of Transient Electromagnetic Soundings

8th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1995
The success of geophysical investigations associated with environmental problems is to a large extent determined by the density of the measurements and the quality of the interpretations. Many case studies of mapping of raw materials and hydrogeological investigations have confirmed that dense measurements with traditional methods of geoelectrical and ...

Electromagnetic transient simulation studies

1999
This chapter describes some research results of EMTP-based digital studies of SPWM UPFC. Useful insights into UPFC performance have been attained through detailed analysis and simulation of the UPFC internal structure and regulation method. Voltage and power control simulation results have demonstrated the functions of the UPFC.

The transient electromagnetic field of a dielectric layer

Applied Mathematics and Computation, 2004
For many years the correlation between the propagation of electromagnetic waves in the atmosphere and meteorological conditions has been a topic of study. The present paper treats this problem in the context of an electromagnetic impulse in an abnormal stratification of the lower troposphere, where the stratification layer is called a surface duct. The

An Electromagnetic Flowmeter for Transient Flow Studies

Review of Scientific Instruments, 1951
An adaptation of the electromagnetic flowmeter has been made for the observation of transients in liquid flows. The device responds to flow transients of 0.001-sec duration, and is not affected by ambient pressure changes or the velocity profile of the liquid in the conduit. The effects of fluid resistivity on the instrument are noted.
