“…As shown in Fig. 8(b), the proposed model is composed of two models, that is, the surge arrester model proposed in [9] and the flashover model described in Section II-A. In the technique proposed in [9], the surge arrester is treated as a lumped-parameter nonlinear resistor, and the nonlinear voltagecurrent relationship is represented by a piecewise linear function based on some discrete points.…”

“…Among the full-wave numerical approaches, the FDTD method is more straightforward to use in terms of handling nonflat ground surfaces and inhomogeneous electrical parameters in the soil and incorporating nonlinear phenomena, and it has been applied to surge analysis [8]. In addition, to apply the FDTD method to lightning surge analysis with nonlinear phenomena, several techniques have been developed to represent lightning surge arresters [9], [10] and flashover phenomena at a long air gap such as arcing horns in high-voltage transmission lines for FDTDbased surge simulations [11] by employing a flashover model developed for circuit-theory-based simulations [12]. The technique used to represent long-air-gap arcing horns in the FDTD method was employed in lightning surge analyses of a 500-kV air-insulated substation [13], [14] and a 275-kV transmission line [15].…”

The operating voltages of low-voltage control circuits in power plants and substations have decreased with the installation of digital control equipment. This increases the susceptibility of control equipment to abnormal surges, which arise mainly from lightning. To protect control equipment from lightning, it is necessary to predict lightning surges invading power plants and substations and design effective lightning protection methodologies. Compared with conventional simulation techniques based on circuit theory, full-wave numerical approaches are advantageous in handling three-dimensional structures such as transmission line towers, grounding structures, nonhorizontal wires, such as incoming power lines to power plants and substations, and lightning-induced effects. In this study, to apply the finite-difference time-domain (FDTD) method to the lightning surge analysis of an air-insulated substation, we first propose techniques for simulating the nonlinear breakdown characteristics of short-air-gap arcing horns and transmission line surge arresters installed in 77 kV transmission lines for FDTD-based surge simulations, and compare the breakdown characteristics calculated using the proposed techniques with measured results for validation. Second, as an example of the application of the proposed techniques to practical surge analysis, it is confirmed that we can reproduce the measured results of lightning surges invading a 77 kV air-insulated substation in the case of a direct lightning strike to its nearby transmission line tower by taking into account lightning-induced voltages arising from the lightning current flowing through the lightning channel and transmission line tower, which are commonly ignored in conventional circuittheory-based simulations, multiphase back-flashover phenomena, and the effect of applied AC voltages.

In this work, the authors have studied the interaction between electromagnetic fields which are generated by lightning and overhead line in electrical power system. For this study, the authors constructed a system of equations. In which the network topology; with all its elements (linear or not) and wave exciter lightning are taken into account. This analysis is developed in time from the general equations of transmission lines with second members, with consideration of the frequency dependence of the correction terms related to the impedance of a finite conductivity of ground as well as non-linearities loads. The simulation results presented in this study demonstrate the effectiveness of this analysis for the calculation of induced voltages generated by lightning on a grid of lines.

In this paper, we propose an efficient modeling technique for incorporating surge arresters in finite-difference timedomain (FDTD) simulations of lightning-induced disturbances in power networks. Instead of using piecewise linear approximations for the V-I curve of an arrester, as usually done in the literature, we derive new updating equations for calculation of electric field components required at each FDTD time step. This is done in a semi-implicit manner where we first obtain a time-stepping relation of electric field based on the V-I curves of the arresters. The time-stepping relation in each time step is solved by the NewtonRaphson method to update the electric field components. The proposed technique is implemented into a nonuniform parallel FDTD code, which is used to simulate a three-phase distribution line of about 800 m equipped with lightning arresters and a neutral wire, installed at the International Center for Lightning Research and Testing at Camp Blanding Florida. The results of FDTD numerical simulations are found to be in excellent agreement with experimental data associated with triggered lightning.
