Back-flashover Investigation of HV Transmission Lines Using Transient Modeling of the Grounding Systems
The article presents the transients analysis of the substation grounding systems and transmission line tower footing resistances which can affect to the back-flashover (BF) or overvoltage across insulator chain in an HV power systems by using EMTP-RV software. The related transient modeling of the grounding systems is based on a transmission line (TL) model with considering the soil ionization....
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 کاملMonitoring and Novel Applications of 220kV/500kV Egyptian Grid Parameters Using family of PMU based WAMS
Egypt is moving towards smart grid infrastructures to enable efficient bidirectional power supply with reduced carbon footprint. The target smart grid will feature distributed energy generation with renewable energy systems. With the improvement of wind power technology in Egypt, increase of wind power capacity, the impact of wind power on the grid has become an important research topic as well...
متن کاملDevelopment of a Fire-Induced Flashover Probability Index (FIFPI) for Eskom Transmission Lines
The need for a fire-induced flashover probability index (FIFPI) for Eskom’s transmission lines (South Africa) became evident soon after the installation the Advanced Fire Information System (AFIS) in 2004. Thousands of wildfires were detected by satellites close to transmission lines, but only a small percentage (4%) of these fires caused a flashover. Historical flashover data was compared to s...
متن کاملSimulation of Lightning Surge Propagation in Transmission Lines Using the FDTD Method
power transmission lines. Numerical computation of solving the Telegraphist’s equations is determined and investigated its effectiveness. A source of lightning surge wave on power transmission lines is modeled by using Heidler’s surge model. The proposed method was tested against medium-voltage power transmission lines in comparison with the solution obtained by using Bewley lattice diagram. As...
