Modelling and simulation strategy for parametric transient electromagnetic simulations
International Journal of Modelling, Identification and Control, 2013This paper presents an efficient two-step reduction strategy for parametric transient electromagnetic simulations. The first step involves the conversion of a large system of parametrised differential algebraic equations (PDAEs), obtained after finite element (FE) discretisation into a significantly smaller system of ordinary differential equations ...

A model for simulating corona in the electromagnetic transients on transmission lines
Computers & Electrical Engineering, 2003Abstract This paper presents a new model for analyzing the electromagnetic transients along transmission lines, which can be totally or partially under corona. Time-domain modeling techniques have been used for representing the line itself by dividing its entire length into an adequate number of identical sections.

Evaluation of STATCOM model for electromagnetic and electromechanical transients
2018 Simposio Brasileiro de Sistemas Eletricos (SBSE), 2018STATCOM is a FACTS (Flexible AC Transmission Systems) device used for improving power system performance. Among other technologies, the STATCOM can be based on the utilization of modular multilevel converters (MMC), which are voltage source converters (VSC), using IGBT instead of thyristor, providing a robust reactive power support for the system. This

Parametric modeling of transient electromagnetic systems
Radio Science, 1979The modeling of a transient electromagnetic system as a single‐input, single‐output, linear, causal process is considered. Two canonical forms are discussed; one for impulse function input and the other for more general input. Expressions are derived for errors in the estimation of the model parameters caused by errors in the process data.

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 ...

A Fast Electromagnetic Transient Modeling for Modular Multilevel Converter
2024 IEEE 10th International Power Electronics and Motion Control Conference (IPEMC2024-ECCE Asia)When the number of sub-modules (SMs) in modular multilevel converter (MMC) is large, the simulation speed usually slows down significantly. In this paper, we propose a fast electromagnetic transient (EMT) modeling to solve this problem.

Modelling of circuit breakers in the Electromagnetic Transients Program
IEEE Transactions on Power Systems, 1988The recent publication of experimental and theoretical results from verified arc models has made possible the implementation and testing of a dynamic circuit-breaker model using the Electromagnetic Transients Program (EMTP). An estimator was developed to obtain model parameters from test data. Results obtained with the estimator are given, and its data
