| Abstract: | Based on the traditional charge simulation method,the computation method of electric field intensity of the high-voltage transmission lines taking account the corona discharge was built.In the paper,it is applied in the computation the 750 kV AC transmission lines'ground level electric field,which is in compact arrangement and in the parallel arrangement.The effect factors are including the conductor coefficient,the sub-conductor radius,the phase spacing,the conductor height,the split-conductor number,and the split-conductor spacing.The simulation results showed that increasing the conductor coefficient and the conductor height can reduce the effect of the corona discharge on electric-field intensity. |
| Keywords: | charge simulation method high-voltage transmission line corona discharge electric field intensity |
