Computation of electromagnetic fields around HVDC transmission line tying EGYPT and KSA

The aim of this work is to compute the electromagnetic fields of a proposed high voltage direct current transmission line (HVDC) tying Egypt and KSA. The line is flat configuration with a stressed voltage of ±500 kV, bundle four, normal height of 30.2 m from ground level to pole conductors and clearance between positive and negative pole of 31.1m. The line is analysed and simulated. The charge simulation method (CSM) is used to calculate the electric field at ground level for that line while the current simulation technique is used to calculate the magnetic fields. The maximum electric and magnetic fields of the line are affected by changing the height from ground level to pole conductors. The effect of pole outage of the line on the spatial distribution of the magnetic and electric field is also studied.
