Question
what is load flow?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
To calculate bus voltage, currents, Mwatts, MVar and power
factor. The results will indicate abnormal conditions of
overvoltage, undervoltage, overload of transformers and
cables.

Answer
# 2
To calculate the system capacity (or power source)or total
load calculation. We can measure also the load divination
according to requirement (so we decided the MCC, PCC CAPACITY).
for ex: In new plant project first we know about the total
load (short ckt current) for deciding transformer rating,
cables, pcc, mcc other equipment.
