| Abstract: | The research on power system black-start after large-scale electric interruption is an important subject for ensuring the secure operation of power systems. The mechanism of internal overvoltage in restoring the non-loaded long distance overhead line during the power system black-start process is analyzed,and the calculation model of overvoltage is established.The general software for simulation of power systems is applied to calculate power frequency overvoltage and switching overvoltage for checking. This study is useful for formulating practical black-start schemes. |

| Keywords: | black-start overhead line power frequency overvoltage switching overvoltage |
