Modelling of a Multipurpose Photovoltaic Generator Block Using ATP-EMTP
IEEE Latin America Transactions, 2019One of the major references to deal with electromagnetic transients is the ATP-EMTP program whose associated tools, ATPDraw (a graphical interface) and MODELS (a programmable language), have pushed its use to other electrical system analysis. In this context, this article aims to show the development of a computational block to represent the ...

Implantation of a static model of the corona effect in the ATP-EMTP software
International Workshop on Systems, Signal Processing and their Applications, WOSSPA, 2011Several mathematical and physical models of corona effect have been developed over the world. The main difference between them resides in the modeling techniques and the adopted hypotheses. To the author knowledge, until now the ATP-EMTP (ElectroMagnetic Transients Program) package does not have such model.

Study on the Identification of Lightning Over-Voltage Based on ATP-EMTP
Applied Mechanics and Materials, 2014Lightning overvoltage often leads to transmission lines trip, which is the weak link of power system. In this paper, 110-kV transmission line model is studied on the basis of the EMTP software. Several simulation models are established for back flashover lightning, induced lightning, shield failure. The transient process of lightning stroke is studied.

An ATP-EMTP Monte Carlo procedure for backflashover rate evaluation
2012 International Conference on Lightning Protection (ICLP), 2012The paper presents the ATP-EMTP implementation of a Monte Carlo procedure aimed at evaluating the backflashover rate (BFOR) of an HV overhead line (OHL). The ATP-EMTP circuit model of the OHL includes detailed line insulation and lightning representation; spatially extended and/or involved grounding systems are represented by a new, simplified model ...

Simulation of Power Line Communication using ATP-EMTP and MATLAB
2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe), 2010In this paper, a simulation test bed for narrowband Power Line Communications (PLC) is demonstrated. The method is able to quickly assess the performance of modulation schemes for an arbitrary network constructed in the ATP-EMTP software, both for point to point and for multi-point to point communication. Demodulation is carried out in MATLAB. The test

Microturbine harmonic impact study using ATP-EMTP
2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat. No.04EX951), 2005ATP-EMTP simulations of a 3-phase commercial power distribution system containing 250 kW, 480 V microturbines running at less than full load and producing harmonic currents that violate recommended current distortion limits are described. The purpose of the simulations was to investigate the extent to which the nonlinear currents generated by the ...

Simulation of VFTO by ATP/EMTP with Various Arc Models
Applied Mechanics and Materials, 2014Several arc models representing a disconnector’s closing operation in a 252kV gas insulated switchgear (GIS) are implemented with a computer program ATP/EMTP to simulate very fast transient overvoltage (VFTO). Arc models are used as black box models in connection with a test circuit.
