POWER FACTOR=TRUE POWER IN WATTS/APPARENT POWERIN KVA


It should be noted that power factor, like all ratio
measurements, is a unitless quantity.
For the purely resistive circuit, the power factor is 1
(perfect), because the reactive power equals zero. Here, the
power triangle would look like a horizontal line, because
the opposite (reactive power) side would have zero length.
For the purely inductive circuit, the power factor is zero,
because true power equals zero. Here, the power triangle
would look like a vertical line, because the adjacent (true
power) side would have zero length.
The same could be said for a purely capacitive circuit. If
there are no dissipative (resistive) components in the
circuit, then the true power must be equal to zero, making
any power in the circuit purely reactive. The power triangle
for a purely capacitive circuit would again be a vertical
line (pointing down instead of up as it was for the purely
inductive circuit).

I am new guy as an electrical engr. in a 100MW HFO based power project. I am in operations division. I have noticed from last few days, my supervisor sends the last 24 hours energy generation calculation to my plant manager. I have noticed, he calculated last 24 hour's generated energy differences in KWH then he multiplied it with a multiplying factor 960. for example: total difference =2.685 KWH*960= 2577.6 MWH. but he does not not know what is multiplying factor 960?? can anybody explain it??

I have tow 200 KVA UPS, both are in parallel mode.My question is that, both are running on battery when power fail, if one of them fail (Eg rectifire fails or some other reason), at thet time reverse power will come to faild ups if it comes then it will harm to failed ups or not? if not then how it protects to faied ups????????????????
