Low-impedance busbar differential protection modeling and simulation using ATP/EMTP
2017 Workshop on Communication Networks and Power Systems (WCNPS), 2017This work describes the modeling of busbar differential protection function by using the MODELS language available in the software Alternative Transients Program (ATP). This type of modeling includes data acquisition and signal conditioning modules for suitably implementing the commercially used 1-out-of-1 and 2-out-of-2 logics. This algorithm is based

Modeling of surge currents in lightning protection system using ATP-EMTP
2014 ICHVE International Conference on High Voltage Engineering and Application, 2014The paper presents computer simulations of current distribution in lightning protection system (LPS) for a small residential structure. The primary objective was the theoretical examination of the current waveshapes in different parts of the circuit and the division of the injected impulse current between the grounding system of the LPS and remote ...

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

Simulation of lightning transients on 110 kV overhead-cable transmission line using ATP-EMTP
Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010Due to construction of a highway in the eastern part of Croatia, a new 110/x kV substation was built with two parallel connecting underground cables. Cables were connected to already existing 110 kV overhead lines. At the place where the transition between overhead lines and cables is made, surge arresters were installed. In this paper lightning stroke

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.
