Electromagnetic transient simulation studies
1999This chapter describes some research results of EMTP-based digital studies of SPWM UPFC. Useful insights into UPFC performance have been attained through detailed analysis and simulation of the UPFC internal structure and regulation method. Voltage and power control simulation results have demonstrated the functions of the UPFC.

Accuracy Evaluation of Electromagnetic Transients Simulation Algorithms
IEEE Transactions on Power Delivery, 2022This paper introduces a novel frequency domain technique to globally evaluate the accuracy of electro-magnetic transient simulations. It is shown that simulation accuracy at low frequencies can sometimes be poorer than at high frequency. A modified approach which quantifies accuracy from a driving point as a function of frequency is also introduced ...

An Efficient Solver for Electromagnetic Transient Simulation
2019In this paper a mesh-free method for electromagnetic transient simulation is presented. This method enables to simulate electromagnetic problems avoiding the use of a regular grid in the discretized model. The proposed method is a particular mesh-free method based on particles, that is no initial regular grid but only an arbitrary particles ...

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.
