CN Tower Lightning Return-Stroke Current Simulation
Different functions have been used to model the lightning return-stroke current with the aid of direct current measurements at tall structures. In this paper, a comparison between the Pulse function and Heilder function is carried out to find out the suitability of each of these functions for simulating the lightning return-stroke current, measured at the CN Tower. An automated system for deter...
متن کاملLightning Surge Analysis on Grounding Models of a Transmission Lines
Lightning has been one of the important problems for insulation design of power systems and it is still the main cause of outages of transmission and distribution lines. The lightning return-stroke current and the charge delivered by the stroke are the most important parameters to assess the severity of lightning strokes to power lines and apparatus. In order to calculate lightning surge analys...
متن کاملImprovements of an FDTD-Based Surge Simulation Code and Its Application to the Lightning Overvoltage Calculation of a Transmission Tower
This paper presents new features recently added to a general-purpose surge simulation code based on the FDTD (Finite Difference Time Domain) method. The added features include various-shape conductor models, lumped-parameter circuit-element models, a lightning-channel model, and an integrated analysis environment (IAE). For precisely modeling the shapes of various conductors, the following cond...
متن کاملImplementation of a Transmission Line Model with the PEEC Method for Lightning Surge Analysis
This paper proposes a simple transmission line model adopted with the partial element equivalent circuit (PEEC) method for lightning surge analysis. The proposed approach is employed for calculating tower surge responses and voltages across insulators of an actual transmission tower. The proposed approach increases the efficiency of the method in terms of computation time because of reducing a ...
متن کاملDevelopment of a Practical Model for Optimizing Surge Tanks and Air Chambers in Water Transmission Systems
Surge tanks and air chambers are the most useful solution to deal with water hammer in water transmission systems (WTS). The optimal design of these protective devices can be effective in reducing the costs of constructing and operating a water transmission system. In this article, some software with the capability of simulating and optimizing these protective equipment is presented. To simulat...
