The probable risk of electromagnetic fields produced
inside high voltage substation is still considered as a competitive
topic for utility designers and biomedical field researchers. Hence,
the electromagnetic field levels and their induction inside human
body should be pre-evaluated as early as the design stage of the
substation. This paper deals with the computation of the
electromagnetic fields induction in human body inside a typical
high voltage 500/220 kV air-insulated substation (AIS). The typical
high voltage substation is simulated by developing multi-scripts of
m-file Matlab software package to calculate individually both of
electric and magnetic fields. Moreover, analytical human body is
simulated and allocated within the highly exposure zones of
electromagnetic fields. The electromagnetic fields induction inside
the human body during live working conditions at different
accessible positions is evaluated based on the finite-difference timedomain
(FDTD) method for solving Maxwell’s equations and the
absorbed power density (w/m2) is calculated using the power
density vector (poynting vector). |
