Early-Time Behavior of the Ground Transient Resistance of Overhead Lines
نویسندگان
چکیده
Ground resistance gives a substantial contribution to the transient response of overhead transmission lines. While the late-time behaviour of the ground transient resistance has been understood quite well, the same cannot be said of early-time behaviour. In this paper, we investigate the early-time behaviour using a high-frequency expansion of the ground impedance in a Taylor series and derive a compact closed-form analytical expression for it. This expression can be used for the transient analysis of transmission lines in a computationally efficient way.

Application of Intelligent Water Drops in Transient Analysis of Single Conductor Overhead Lines Terminated to Grid-Grounded Arrester under Direct Lightning Strikes
In this paper, Intelligent water drop algorithm (IWD) is used to analyze single overhead line connected to grid-grounded arrester. In this approach, at first Norton’s equivalent circuit of the overhead line over lossy soil is computed by method of moments (MoM) and then for the problem under consideration, a nonlinear equivalent circuit in the frequency domain is proposed. Finally applying inte...
متن کاملA new expression for the ground transient resistance matrix elements of multiconductor overhead transmission lines
The ground impedance matrix elements of a multiconductor overhead transmission line do not have analytical inverse Fourier transforms in the time domain. Thus, in general, the ground transient resistance matrix elements are to be determined numerically. Using the low-frequency approximation analytical expressions are available for the ground transient resistance. These expressions present howev...

In this paper, genetic algorithm-based approach for transient analysis of single transmission line connected to arrester is proposed. In this approach, the lightning channel striking the overhead line is first represented by a current source and this source is truncated by a finite set of frequency harmonies in time domain. Norton equivalent circuit viewed across arrester is then computed by me...
متن کاملOn Calculation of the Ground Transient Resistance of Overhead Lines
A constraint on the calculation of the ground transient resistance of overhead lines for small values of time is pointed out. The method for overcoming this constraint is proposed. The source of the ground transient resistance singularity is the low-frequency approximation of the ground impedance. It is shown that the ground transient resistance is not singular for t! 0 if it is calculated with...
متن کاملOne Terminal Digital Algorithm for Adaptive Single Pole Auto-Reclosing Based on Zero Sequence Voltage
This paper presents an algorithm for adaptive determination of the dead timeduring transient arcing faults and blocking automatic reclosing during permanent faults onoverhead transmission lines. The discrimination between transient and permanent faults ismade by the zero sequence voltage measured at the relay point. If the fault is recognised asan arcing one, then the third harmonic of the zero...
