| Abstract: |
| As the lightning intruding wave may destroy the insulation of electrical equipments in high-voltage substation，a simple lightning overvoltage calculation method is proposed based on Bergeron equivalent model，which simplifies the multi-catadioptric problem of waves on the finite line，as well as the network equations and calculation program. The Bergeron equivalent models of lossless uniform conductor and lumped parameter elements are described and the mathematical models of 500 kV substation electrical equipments with lightning overvoltage are established. The overvoltage is calculated for 500 kV substation inlet line undergoing lightning intruding and its distribution on equipments is obtained，which proves the proposed method is effective. |
