Abstract: Overvoltage and its accidents are common,which seriously threatens the stability and reliability of power system.It is necessary for power grid to obtain accurate,high-quality overvoltage data,as is one of the basis for the precisely transient analysis modeling and safe operation of power system.Previously some relevant research has captured a mess of overvoltage data,meanwhile errors or invalid waveforms are incorporated into the overvoltage database,the low quality data results in valueless an... More
