generaly all power generating devices is expressed in KVA
or MVA then why power ststion is expressed in MW
Answer Posted / anubis
KVA or MVA is used to measure apparent power. MW is used
for real power. Since the resistance and reactance for a
generating device is known, the apparent power can be
calculated. For the power station the apparent power will
not only depend upon the internal impedence of the station,
and the wies, but also upon the grid. This is not a fixed
number and varies with conditions, thus making it
impossible to judge. Thus it is safer to just give the real
power and then calculate th apparent power depending upon
the load used.
