“…The proposed modelling technique can be extended to represent three-phase lines by lumped parameters using modal decoupling, as is well established in the technical literature on TLM [7,8,12]. A three-phase line can be decoupled into three independent propagation modes, which can be modelled as three single-phase lines using the lumped-parameters approach and the proposed filtering technique, as shown in Fig.…”

An efficient and simplified procedure is proposed for the reduction of high-frequency oscillations and erroneous magnitude peaks in electromagnetic transient simulations in power transmission systems modelled by the lumped electric parameters approach. This procedure consists of the inclusion of analogue filters in the equivalent representation of multiconductor transmission lines without modifying its electromagnetic propagation characteristics. The analogue filter modelling is conducted as a function of the line length and line parameters. The proposed simulation methodology is applied directly in the line modelling, which means that the filtering/correction process represents a real-time process during simulations, without post-processing filtering techniques using digital filters or variations in the solution methods. The results obtained directly in the time domain by the proposed modelling/simulation methodology are compared with simulations obtained from well-established line models using the numerical Laplace transform and the Bergeron method.

“…As well-established in the technical literature on TLM, the impedance of transmission lines is highly dependent of the frequency due to the earth-return current (soil effect) and the skin effect in the conductor. This means that the transmission lines are characterized by a longitudinal impedance ZðxÞ, resulted from the soil and skin effects [5,7,8]. Thus, the inclusion of the frequency effect in transmission line models is an important issue for simulation of electromagnetic transients.…”

A new transmission line model is proposed based on the well-established Bergeron method. The conventional Bergeron model is characterized by the line representation by concentrated longitudinal and transversal parameters, i.e., electrical parameters of the line are represented by means of electric circuit elements. The original approach of this research is the inclusion the frequency effect in the longitudinal parameters of the Bergeron line representation. In order to increase the frequency range covered by the proposed model, the line is represented by a cascade of line segments which are modeled following the proposed frequency-dependent Bergeron circuit. The differential equations resulted from the proposed development are represented by state matrices. The line representation by cascade of frequency-dependent Bergeron circuits enables to extend the application of the new modeling technique for simulations considering a wide range of frequencies, from a switching up to an atmospheric impulse. The proposed line model is validated based on results obtained from the well-established line model using numerical Laplace transform.

“…Although PI-section transmission models are extensively used, it has drawbacks of resulting in oscillations due to the lumped parameters [9]. Several solutions have been developed and post processing filters methodology is proposed to attenuate the oscillations [10].…”

In power systems, compensation techniques are used to improve the power transfer capacity in the transmission lines. Controlling the voltage profile along the line helps to control the transmittable power and this is achieved through compensation techniques. In this paper, different line models are used for the estimated power transmitted in the line both with and without shunt compensation. It is observed that with the Bergeron line model and PI-section model the estimated power is higher compared to that with the series RL model both with and without shunt compensation. PSCAD is used for the simulation.
