Abstract |
The outages of transmission lines give big damages to the industrial world Lightning outages occupy above 50[%] among the outages of transmission lines. To decrease the lightning outage rates, it is necessary to by countermeasures considering economical points. For the lightning protection of power transmission lines, it is very important to accurately predict the lightning outage rate because the reliability criterion for transmission line is normally specified as the number of flashovers per 100[㎞] per year. The phenomenon of an insulator flashover by a lightning stroke is a very complex electromagnetic event. And to calculate the lightning outage rates of transmission lines, so many calculation should be repeated because there are many overhead lines and power lines. Therefore it is necessary to develope a program for it. In this paper, we briefly introduce the basic concept for lightning outage calculation algorithm and the program. |
