Accurate Frequency Dependent Cable Model for Electromagnetic Transients
IEEE Transactions on Power Delivery, 2016This paper introduces a new frequency-dependent cable model for the simulation and analysis of electromagnetic transients. The model belongs to the traveling-wave class. The key feature of the proposed model is the correct representation of modal propagation function contributions in the phase domain.

An Efficient Synchronous Machine Model for Electromagnetic Transients
IEEE Transactions on Power Delivery, 2011This paper proposes a new synchronous machine model based on the application of Park's transformation to the discretized equations of the phase-domain model. The proposed approach maintains the precision of the phase-domain model and eliminates its computational inefficiencies through a constant admittance matrix. The model includes magnetic saturation.

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

2018 International Conference on Power System Technology (POWERCON), 2018
With the wide application of power electronic technologies in power system, such as HVDC, new energy power stations and FACTS, the dynamic characteristics of the interconnected power grid have changed dramatically, and the traditional quasi steady model based electromechanical transient program cannot simulate the fast switching process of the power ...

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 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.

Modeling hysteresis in electromagnetic transient studies
1995Abstract A hysteresis model is presented in this paper for electromagnetic transient analysis of power system network involving ferromagnetic elements. The major hysteresis loop is represented analytically and the minor hysteresis loops can be created automatically in terms of a displacement varying with nonlinearity.

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 ...

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.

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.
