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.

A PMU Model for Wide-Area Protection in ATP/EMTP
IEEE Transactions on Power Delivery, 2016Phasor measurement units (PMUs) are the key components in modern wide-area monitoring, protection, and control systems. This paper addresses the development of a PMU model in the Alternative Transients Program/Electromagnetic Transients Program. The performance of the proposed PMU model is assessed during normal and abnormal operating conditions using ...

Grounding Grid Transient Simulation and Its Application Based on the ATP-EMTP
2012 Third International Conference on Digital Manufacturing & Automation, 2012A transient grounding grid numerical model is developed in this paper for calculation of grounding grip transient response fast and accuratelyi£This model considers the ground as some conductor segments, each conductor section as a grounding unit. The transmission-line modeling method was used to this model.

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.

Simulation of the effect of voltage transients on an induction motor with ATP/EMTP
2009The present study aims at understanding the behaviour of the induction motor when subject to different kinds of disturbances. The intention was to broaden the study of some disturbances by using a transient simulation software, ATP/EMTP, and comparing results with laboratory measurements.

Complex R-X Diagram for Mho Relay Visualization in ATP/EMTP
2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC), 2020Overhead transmission lines are probably the electrical component most vulnerable to lightning, short circuits, human errors, overloads and ageing due to the long trajectories they have. In this paper, the operation of the Distance Relay (21-ANSI/IEEE Standard Device Number) as primary or main protection as well as backup protection for overhead ...

The Calculation of 750kV Line Parameters Based on ATP-EMTP Simulation
2016 International Symposium on Computer, Consumer and Control (IS3C), 2016Transmission line is one of the major components of the power system. It is great significance to accurately obtain the frequency power parameters of transmission line for the entire power system to operate safely and reliably. In order to acquire the power frequency parameters of 750kV overhead line, a new method is proposed in this paper. This method
