Analysis on Three-dimensional Hybrid Electric Field and Related Electrostatic Induction Effect of ±800 kV DC and 500 kV AC Parallel Transmission Line Considering Rainy Days
摘要
Abstract
In order to confirm the effect of hybrid electric field below ±800 kV DC and 500 kV AC parallel transmission line on the human body in rainy days,considering rainy environment,we calculated the three-dimensional nominal electric field and ion flow field below the ±800 kV DC and 500 kV AC parallel transmission line by combining the three-dimensional optimized charge simulation method and the Deutsch hypothesis.Moreover,the hybrid electric field was calculated by Matlab.The calculated results show that the electric field distribution near the ground in rainy days is wavy.In rainy days,the electric field has some shielding effect.And with the increase of rainfall intensity,the shielding effect is stronger.When people stand in the rain with an umbrella,the electric field near the top of the head is distorted,but the induced current density and induced current on the surface of the human body are basically within the safety range stipulated by the INCIRP,so the human body will not be hurt.关键词
