Field Profiles Underneath and Between Proposed Hybrid Power Lines in Egyptian Grid

The great destination of this research manuscript is focusing to evaluate the electric and magnetic field profiles between and closed to submitted hybrid power lines in Egyptian grid. Three hybrid lines are patterned and modeled. The first arrangement is double-circuit operating with AC voltage of two hundreds and twenty kilo voltage parallel with bipolar circuit of DC voltage of ±500 kV, while the second arrangement is flat working at 500 kV AC and parallel with ±500 kV DC circuit. The third one constitutes of one circuit AC with voltage of 220 kV and one DC circuit stressed with voltage of ±500 kV on the same pylon. Two numerical mechanisms were applied to estimate the field profiles beside and among the presented lines. The first mechanism is the charge emulation technique (CET) for electric field estimation and the second one is the current emulation mechanism (CEM) for magnetic field evaluation.
