Computation of Electromagnetic Transients
Proceedings of the IEEE, 1974Switching operations, faults, and other disturbances produce surges on transmission lines and oscillations in transformer and generator windings. Such electromagnetic transients have primarily been studied with transient network analyzers since the late 1930's. In recent years, digital computer programs have been de-.

Computation of Transient Electromagnetic Fields Due to Switching in High-Voltage Substations [PDF]
IEEE Transactions on Power Delivery, 2010 Switching operations of circuit breakers and disconnect switches radiate transient electromagnetic fields within high-voltage substations. The generated fields may interfere and disrupt normal operations of electronic equipment.

Firefly Algorithm for Transient Electromagnetic Inversion
IEEE Transactions on Geoscience and Remote Sensing, 2022Transient electromagnetic (TEM) method is widely used in regional mineral resources surveys, environmental engineering geological surveys and shallow surface geophysical exploration, and so on. However, interpretation and inversion of TEM data is a complicated process.

Electromagnetic Transients and Modelling
2019Transients are the norms and the musts of the energy conversion in power electronics systems. Previous research is focused on the large-timescale electromagnetic transient processes, while neglecting short-timescale switching processes and stray parameters. When failure mechanisms of components and the enhancement of the power-conversion capability are

Transient electromagnetic field
European Journal of Physics, 1997The transient and asymptotic solution of the Maxwell equations for a system of two bidimensional particles of opposite charges is studied. Initially the particles are at rest at the same point, then one remains motionless while the other drifts at constant velocity.

Electromagnetic Interference Prediction in Transient Electromagnetic Environment
2007 International Symposium on Electromagnetic Compatibility, 2007This 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, 2021This 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 ...
