With the development of cities and electric power
industry, the demand of electrical energy, generation,
transmission, distribution and the voltage levels have increased
considerably. Therefore the power frequency electric field and
environmental impact assessment near and under the high
voltage overhead busbars, incoming and outgoing feeders inside
the high voltage substations (HVS) have caused wide public
concern. Nowadays most research on electric field are concerned
with calculation the electric field distribution around the
transmission lines, insulators and cables but they rarely
concerned with its calculation in busbar area inside HVS. In this
paper, a different type of calculation is achieved, the charge
simulation method (CSM) is employed to analyze the three
dimensional (3-D) electric field distribution near and under the
busbars, incoming and outgoing feeders. Also, the effect of
changing the level of operating voltage, the space between the
phases, the level of calculation inside HVS is demonstrated |
