Evaluation of Corona and Line Models in Electromagnetic Transients Simulations
IEEE Power Engineering Review, 1991The main purpose of this study is to make a comparative evaluation of the large number of available corona models in terms of their accuracy and suitability for interface with the EMTP (electromagnetic transients program). The recommended models have been interfaces with the standard frequency dependent transmission line model in the EMTP.

A smoothed particle interpolation scheme for transient electromagnetic simulation
IEEE Transactions on Magnetics, 2006In this paper, the fundamentals of a mesh-free particle numerical method for electromagnetic transient simulation are presented. The smoothed particle interpolation methodology is used by considering the particles as interpolation points in which the electromagnetic field components are computed.

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

z-transform-based methods for electromagnetic transient simulations
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2007This is an introductory paper on z-transform-based methods for electromagnetic transient simulations of power systems. Since the theory of the z-transform was originally developed for the analysis of time series data defined at equidistant time steps, simulation models developed using z-transforms can readily be used in electromagnetic transient ...

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.

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.
