Modeling of Inverter-Based Resources Using Equivalent Current Sources in EMTP-RV

2020 IEEE Power & Energy Society General Meeting (PESGM), 2020
This paper presents a time-domain, equivalent current source model (CSM) for inverter-based resources in EMTPRV for evaluating their harmonic impacts, behavior, and interactions with the grid. Whereas detailed inverter models can be accurate if the inverter design and parameters are precisely known, their simulations are time-consuming.

Simulation of transient regimes from a naval power system using EMTP-RV

Eurocon 2013, 2013
This paper presents the simulations made with a special software (EMTP-RV) for the analysis of transient regimes corresponding to the disconnection of a generator from the supplying bars from a power naval system, which is a system with limited power. One could determine the effects of driving various protections at the chosen timings.

EMTP-RV Analysis of Lightning Surges on Wind Turbines

RE&PQJ
This paper is concerned with lightning surge propagation on wind turbines. As wind power generation undergoes rapid growth, lightning incidents involving wind turbines have come to be regarded as a serious problem. Nevertheless, no known studies exist yet in Portugal regarding lightning protection of wind turbines. Hence, we present a case study,

EMTP-RV Model of Hydraulic Digital Governor

International review on modelling and simulations, 2011
This paper presents EMTP-RV model of hydraulic digital governor. Based on block scheme of a digital turbine control system, a novel EMTP-RV model of hydraulic digital governor for stability studies has been developed. Developing of hydraulic digital governor is an important step in achieving a fully integrated system for stability studies.

Power Transformer and Surge Arrester Modeling for Fast Front Overvoltages Using EMTP-RV

2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D), 2020
Inadequately rated surge protection devices in a power system can result in partial, complete as well as catastrophic damage to assets from overvoltages. A conservative approach could be to adopt the highest value(s) of rated insulation level for a given voltage class, however, this approach may be uneconomical and impractical.

EMTP RV-based study of solid-state fault current limiter for distribution systems

2006 IEEE Power India Conference, 2006
A 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.
