Actually DG size has to select depends on maximum demand
and considering base load and starting load and step load
base load = total maximum demand - loads which are
taking high loads at startign
starting load = if motor loads are DOL starts 6 times to
the Ifl will take at starting and soft
starters /VFD's will take 3 times to Ifl
step load = Whwn the main power supply is off
immidiently what are the load we can
switched ON through DG -called step load
(generally 40-60% of Dg load can be ON as
first step)
So our selected DG shopuld meet the step load and capable
to withstand startign loads
