Efficient simulation of electromagnetic transients in power networks

In this paper is proposed a high level programming approach based on data structures for the accurate and efficient simulation of electromagnetic transients in electric circuits and power networks. The proposed methodology uses the nodal analysis technique as in the commercial EMTP-type programs to update voltages and currents in the power network. In addition, it is used the numerical trapezoidal integration rule to solve the continuous differential equations of each power system component. This program is implemented in MATLAB^® with a minimum of code lines and is capable to get the same waveforms of commercial EMTP-type programs such as PSIM^® and RSCAD^®. Finally, the proposed programming approach has the flexibility to incorporate new components of power systems regardless of their complexity.
