Stability Analysis of Electromagnetic Transient Simulations
2018We present an analysis of the stability characteristics of the discretized Maxwell-Ampere equations that result from a finite integration of the potential formulation. We demonstrate that the derivation of the discrete versions of these equations will result into unstable formulations unless, in the conversion from a continuous expression to a discrete

Modeling of a buried conductor for an electromagnetic transient simulation
IEEJ Transactions on Electrical and Electronic Engineering, 2006AbstractThe paper has proposed a distributed‐line model of a buried bare conductor with horizontal and vertical configuration by assuming an artificial insulator outside of the bare conductor so that the characteristic impedance and the propagation velocity of the buried conductor is evaluated as an insulated conductor (cable) by the cable constants ...

Electromagnetic Transient Simulation of Hybrid Electric Vehicles
2007 IEEE International Symposium on Industrial Electronics, 2007The paper presents a procedure for modeling emerging hybrid and electric vehicle drive-trains in a transient simulation program. The benefit of such models is that they enable detailed studies to be carried out on the performance of the drive-train through detailed modeling of drive motors, power converters, and energy storage subsystems.

Modeling and Simulation of ±800kV HVDC Electromagnetic Transients
2020 Asia Energy and Electrical Engineering Symposium (AEEES), 2020With the dense access of Large-scale high voltage direct current (HVDC), the problem of AC and HVDC interaction is prominent. To ensure the safe and stable operation of AC/DC hybrid power grid, it is necessary to accurately simulate HVDC transient and steady state according to the actual control program.

Transient simulation of helical coil electromagnetic launchers
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2018Purpose Helical coil electromagnetic launchers (HEMLs) using motion-induced commutation strategy solve the problem of synchronization control perfectly. HEMLs can meet the requirements of multiple applications such as the electromagnetic catapult, electromagnetic mortar and high-velocity coilgun. The trade-off between the velocity and efficiency is an

Investigation of the use of electromagnetic transient models for transient stability simulation
6th International Conference on Advances in Power System Control, Operation and Management. Proceedings. APSCOM 2003, 2003This paper presents the advancement in enhancing the transient stability simulation with detailed device level modeling of power electronic devices such as FACTS and HVDC. An electromagnetic transient (EMT) model of an SVC has been built and incorporated into a conventional transient stability (TS) program.

Transient Simulation of Electromagnetic Forming of Aluminium Tubes
Advanced Materials Research, 2005The recent push to use more aluminium in automobiles has stimulated interest in understanding electromagnetic forming (EMF), which uses induced electromagnetic fields to generate high strain rates during the forming process. The high strain rates increase the formability of aluminum materials and might reduce elastic spring-back and wrinkling of the ...

Simulation of Electromagnetic Transients in Power Systems
2012Transients in power systems are initiated by abrupt changes to otherwise steady operating conditions. These changes would be as a result of any of the following: opening or closing of circuit breakers, switching conditions, lightning or any other fault condition.

Synchronous generator models for the simulation of electromagnetic transients
2010Techniques for modelling of synchronous generators in the simulation of electromagnetic transients are described. First of all, an adequate mathematical model of the generator is established. It uses the conventional set of generator data only, which are readily available, but it is flexible enough to accommodate additional data, if and when such ...
