| Abstract: | Based on wring mode and line parameters of 500 kV PaichangⅡ,this papers computes power frequency over-voltage rising times of no-load long line, then builds simulation model of 500 kV Paichang Ⅱ line and simulates power frequency voltage rising and switching over-voltage times in different operation mode by electromagnetic transient simulation software ATP . Combining simulation results and test situation,this thesis proposes the best method. |
