“…The transient analysis of overhead lines in the presence of surge arresters is generally a difficult task because of the impulse characteristics of complex grounding grids and nonlinear behavior of the arresters. There are several approaches either in the frequency domain 1‐3 or in the time domain 4‐6 . The frequency‐domain methods can easily incorporate the frequency dependence of electrical parameters of ground (dispersive ground) with inherent difficulties in dealing with non‐linear elements 2 .…”

In this paper, an efficient hybrid method is proposed for transient analysis of an overhead line equipped with a grounded arrester. The proposed method adopts a nonlinear equivalent circuit consisting of linear and nonlinear parts respectively associated with the overhead line and the arrester. In the first part of the paper, an intelligent model based on qualitative concepts in electromagnetics is proposed for derivation of the linear part. With the use of this qualitative model, the behavior of the linear part is first extracted as simple and unchanged membership functions, and effects of parameters of the problem, that is, the height of the overhead line and the electrical parameters of the ground, are then extracted as simple curves so that the linear part based on the qualitative model is efficiently computed in the frequency domain. The qualitative model, in contrast with the conventional numerical methods, is very efficient, and in comparison with the approximate ones, is broad band. In the second part of the paper, with the aid of an efficient optimization algorithm, called intelligent water drop algorithm (IWD), the lightning overvoltage across the arrester is efficiently computed.

“…In addition, time-domain solutions can be obtained without frequency-time domain transformations. To apply the FDTD method to surge analyses, several techniques for representing thin wires [9][10][11], surge arresters [12,13], arcing-horn flashover models [14], and so on have been developed, making the method an effective tool for the study of electromagnetic transient phenomena in power stations, substations, transmission lines, distribution lines, and buildings [15,16]. For direct or nearby lightning strikes, the FDTD method has been used to study electromagnetic fields and voltages induced on electrical wires inside buildings and the effect of building structures [17][18][19][20].…”

The finite‐difference time‐domain method is one of the most widely used numerical electromagnetic computation techniques, and it has become an effective tool for analyzing electromagnetic transient phenomena in three‐dimensional structures and grounding systems. However, the available approaches for representing thin wires apply only to bare conductors such as overhead power lines and earth electrodes. In this work, we demonstrate the applicability of thin‐wire representation techniques to wires surrounded by both lossy and lossless media, such as reinforcing bars inside lossy concrete. The validated technique is then illustrated through the study of a reinforced‐concrete building struck by lightning to evaluate the effect of concrete on the penetration of lightning electromagnetic pulses inside the building. © 2019 Institute of Electrical Engineers of Japan.

“…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.
