Research on Operation Overvoltage of Extrahigh Voltage Line Based on Software of PSCAD/EMTDC

Yi Tu

Abstract

The operation overvoltage of extrahigh voltage line is analyzed theoretically.The results are validated by PSCAD/EMTDC simulation,and the simulation results also show that the trip overvoltage is mainly related to the line current and the power establishing width angle when tripping occurs.It is also shown that the switch on overvoltage is mainly related to the residual voltage before switching.
