ABSTRACT

In order to ensure the safe and reliable operation of transmission lines, a calculation model of electric field of EHV electronic lines based on field strength correction model is proposed. The model is simulated, and the nominal electric field intensity distribution of different models is compared with the four bundles conductor overhead ground wire model. The results show that the influence of the overhead ground wire on the nominal electric field strength around the transmission line is very small, so it is feasible to use the simplified model of ignoring the overhead ground wire in the engineering application; the simplified model of the equivalent conductor is not suitable for analyzing the electric field strength near the line, but suitable for analyzing the area far away from the line and the calculation amount is greatly reduced.
