Lightning arrester modeling using ATP-EMTP
2004 IEEE Region 10 Conference TENCON 2004., 2004This paper describes operating analysis of metal oxide surge arrester, IEEE and Pinceti model, using ATP-EMTP. Nowadays the Provincial Electricity Authority (PEA) and the Metropolitan Electricity Authority (MEA) mostly use lightning arrester from Ohio Brass and Precise brand.

POREĐENjE SOFTVERSKIH ALATA ATP/EMTP I SIMULINK U KOORDINACIJI IZOLACIJE
Zbornik radova [Elektronski izvor], 2023The paper demonstrates the procedure of risk assessment of electrical equipment insulation failure due to atmospheric lightning using various software tools. When applying any method for determining the risk of insulation failure, it is necessary to repeat a number of simulations of the transient process due to atmospheric lightnings in order to see ...

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 narrowband power line communication using ATP-EMTP
41st North American Power Symposium, 2009The simulation of narrowband power line communication is carried out by use of the J. Marti line model in the ATP-EMTP simulation program. The modal attenuation constants for three distribution line structures are obtained and frequency domain simulations on a ‘typical’ rural 11 kV network are carried out.

Bewley’s Lattice Diagram Implementation by using ATP/EMTP
IEEE Latin America Transactions, 2019Transients caused by lightning that strikes to transmission lines, switching operations or faults, are fundamentals in selecting equipment insulation levels and protection devices. Thus, studies of electromagnetic transients on transmission lines have demonstrated that when a change on the normal operation of the system takes place, voltage and ...

Transient analysis of a distribution transformer using ATP-EMTP
2018 1st International Conference on Power, Energy and Smart Grid (ICPESG), 2018The paper reports investigation on different parameters of an 11-kV line that affect the lightning impulse failure of a distribution transformer in Pakistan. The equivalent model of the transmission system was developed in ATPDRAW, and the simulations have been carried out in Alternative Transients Program — Electromagnetic Transients Program (ATP-EMTP)

Simulation of power system dynamic phenomena in ATP/EMTP
2014 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC), 2014Recent developments in synchronized voltage phasor measurements has made wide area protection and control schemes possible. Recently, wide area disturbances has forced utilities to design protection and control schemes to protect the power system from angular, voltage and frequency instabilities, in order to avoid a complete or partial blackout.

Islanding detection active methods: Implementation of simulation models using ATP-EMTP
Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010, 2010Distributed generation (DG) units are rapidly increasing and most of them are interconnected with distribution network to supply power into the network as well as local loads. Islanding operations of DG usually occur when power supply from the main utility is interrupted due to several reasons. Islanding conditions cause negative impacts on protection,
