Lightning stroke characteristic assessment method

Abstract

The invention discloses a lightning stroke characteristic assessment method which includes the following steps of: (1) determining a lightning stroke model; (2) determining a tower model and impulse grounding resistance; (3) determining an insulator model and flashover criteria of the insulator model; (4) selecting a line model and a matched load; (5) changing the neutral point grounding modes; (6) measuring zero sequence current values and neutral point potentials in different grounding modes. The lightning stroke characteristic assessment method has the advantage of being capable of being used for accurately assessing the effect of difference of the neutral point grounding modes in a 10kV lightning stroke characteristic on the lightning stroke characteristic.

AI Technical Summary

Benefits of technology

This new technology helps evaluate electrical cables' ability to protect against heavy rain without causing disruptions or damaging them during their use. It uses an algorithm that predictes how much it will hit each other when exposed to strong sunlight compared to its surrounding area. By doing this, researchers are able to better identify potential hazards associated with these wires. Additionally, they suggest selecting appropriate reconstructed sections within specific regions where there may have been significant damage caused due to high levels of solar activity. Overall, this innovation improves safety standards for power transmission networks while ensuring reliable operation over time.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of an electricity distributor's protective system against lightening attacks (LF) while maintaining its ability to detect and respond quickly to any failures such as lightnings strike events. Current methods involve resistors placed at specific points along the transmission route to prevent electrical discharges from damaging underground cables. However these conventional techniques may still result in temporary arcs causing equipment failure and potentially increasing health hazards associated with LFL.
