초록
This paper describes the TNA(Transient Network Analyzer) modeling/operating methods and the analysis results of expected overvoltages of 765 kV system in 2005 by the TNA. The power system is expressed as the equivalent inductance of power system, power source, transmission line, switch, and etc. in the TNA. We have examined the overvoltages in the ground fault case, the fault clearing case and the closing/re-closing case. The maximum line-to-line overvoltage is 1.87 p.u., which occurs between SS and SA at the fault clearing case.
