Application of the Heidler function in electromagnetic transients programs [PDF]
Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2021 The paper analyzes the possibility of using the Heidler function in programs for electromagnetic transients. The parameters of the Heidler function are calculated for various standard waveforms, where greater accuracy is shown for certain waves than with

Modelling of Secondary Arc Using EMTP-RV [PDF]
The Transactions of The Korean Institute of Electrical Engineers, 2012 Most of faults occurred in transmission lines are single-phase to ground faults and transient faults. Single-phase auto reclosing is an appropriate scheme to maintain the system stability and restore the system effectively when those faults are occurred.

Power-Smoothing Scheme of a DFIG Using the Adaptive Gain Depending on the Rotor Speed and Frequency Deviation [PDF]
, 2017 In an electric power grid that has a high penetration level of wind, the power fluctuation of a large-scale wind power plant (WPP) caused by varying wind speeds deteriorates the system frequency regulation. This paper proposes a power-smoothing scheme of
