EMTP RV-based study of solid-state fault current limiter for distribution systems
2006 IEEE Power India Conference, 2006A fault current limiter (FCL) can reduce the fault current in a feeder system to a desired level and permit continuous power to be fed to loads. An EMTP RV based study to limit fault currents in a distribution system using a solid-state fault current limiter (SSFCL) is presented in this paper.

STATCOM model in EMTP RV using hysteresis current controlled voltage source converter (VSC)
Canadian Conference on Electrical and Computer Engineering, 2005., 2006In this paper, a static compensator (STATCOM) model in EMTP RV of a voltage source converter (VSC) is presented. The STATCOM is connected to the end of a transmission line. The DC/AC conversion is obtained by using pulse width modulation (PWM) based on a current hysteresis controller.

Current Transformer modeling in EMTP-RV for transients studies
2012During the last decades the demands on current transformers for protection has increased rapidly. Overcurrents in power networks and also time constants for the short-circuit DC offset are increasing. Very short breaker tripping times are stipulated and achieved by fast operating protective relay systems.

Izrada modela vodikovih gorivih ćelija i implementacija modela u EMTP-RV softver [PDF]
, 2020 Model vodikove gorive ćelije je razvijen i implementiran u EMTP softveru. Matematički model vodikove gorive ćelije je izrađen na temelju postojeće literature. Za razliku od većine dostupnih matematičkih modela, implementirani model može simulirati ponašanje bilo koje vodikove gorive ćelije, a koja koristi vodik kao gorivo i zrak kao oksidans.

Basis for the development of new toolbox for short-circuit studies in EMTP-RV
2018EMTP-RV software has been used for a few decades mostly for slow and fast transients. The most typical studies were indeed lightning surge and transformer energization. New modules have been developed quite recently to enlarge the scope of studies that can be easily done with EMTP-RV (stability, protections, lightning induced overvoltage, parametric ...
