Answer / rajani
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

Answer / sheo
Suppose LOAD-1000 KW
So design load of Genset @ 80% inefficiency.
and power factor @80% in case of ( Failure of capacitor)because life of Capacitor and Gen set never equal to each other.
so 100% power back-up for 1000 KW load required DG 1000/0.64=1562.5 KVA
Recommended DG-1500 KVA

Answer / rakesh kumar sharma
generally the efficiency of the D.G.set is 80% because of
the power factor.so u have to add 20% on the entire
load.

Answer / sijish
DG normaly loads up to 80% of the full load rating,
First step.Calaculate the load in KW.
Consider the staring current of the Load.
The minimum Amps rating of the dg shoul be 4 Times the
Running current of the motor load

Answer / anil
Depending up on the total load to select the dg.for 5kw
load 10kva DG is suitable.
dg can be loaded for 80% of full load ,ie 8kw
calculating PF 6.4 kw can be loaded in 10kva dg.

Answer / m.prabhakar
Depending up on the total load to select the dg.For example
180KW load is there 200kva capacity genarator is sufficient.
