Improving power efficiency demands lower impedance power distribution for less loss through I2R loss
and less inductance for faster regulation.
With a fixed slot area, the only way to increase conductor size and lower I2R loss
is by increasing the slot-fill factor ([S.sub.ff]) given by the following equation:
The total real power loss (I2R loss
) in a distribution system consisting of b branches can be written as
Higher-voltage operation is key to efficiency, since it reduces I2R loss
. In addition, by using a one-stage down conversion chain instead of two stages (i.e.
Thus, the primary and secondary distributions lines in rural areas caused high line resistance and I2R losses
in the line.
are minimized when operating at these voltage levels and this helps maximize power delivery to the end-equipment and improve efficiency.
