| Abstract: | In a modern power system,inappropriate operation or fault handling may cause calamitous outages and lead to widespread blackout.During the process to work out black-start scheme of power system,it is necessary to repeatedly calculate and verify the overvoltage of the energized transmission line for various black start schemes.The mechanism of internal overvoltage in restoring the non-loaded long distance overhead line during the power grid black-start process is analyzed,BPA and ATP that the general software for simulation of power systems are applied to calculate power frequency overvoltage and switching overvoltage for checking.The results show that the overvoltage is within the extent of design criteria.This study is useful for formulating practical black-start schemes. |
| Keywords: | black-start power frequency overvoltage switching overvoltage BPA and ATP |
