Hi Guys,
Firstly, I apologize to all my friends on AAC for adding one more thread to the already existing clutter of nonsensical threads started by me. I tried my level best to solve this doubt pertaining to physics of Load Sharing on my own with whatever study material I have, but in vain (browsing the net didnt help me either). As a result, I had no option but to put it up as an extra thread on this forum. I hope you guys would be kind enough to bear with me!
But before I start my never ending rant, I want to clarify that this problem is theoretical in nature and not related to the practical conditions pertaining to large generators hooked up to large power grids (Infinite bus).
Consider two power sources A and B (DC generators/batteries . I have considered DC power for clarity), connected in parallel and sharing a common load. Suppose I increase the EMF of say, source A (EMF of source B remains un-altered). On applying Superposition Theorem I found that the terminal voltage Vt across the load would obviously rise also resulting in an increase in the total load current I(load) .so far, so good.
But then I tried comparing the above results with the Terminal voltage Vt versus Load current I(load) characteristics of two DC generators operating in parallel and sharing a common load. I observed that if the EMF of say Gen A is increased, Gen A takes up more load with a significant increase in the bus terminal voltage Vt across load.
However, according to the Vt I(load) characteristics, in spite of the increase in Vt, the load current and hence output power is shown to remain constant.
This, in my opinion, directly defies Ohms Law ..which in turn is the cause of my doubt.
A voltmeter joined parallel with the connected load would then never indicate the rise in Vt as the voltmeter current Iv(however small) is now part of the total load current I(load), but which remains constant {according to the Vt - I(load) characteristics} as mentioned above.
Any kind of help/suggestion in this regard will be greatly appreciated ..or else, this thread too will be destined for (like several others before it), a pre-mature demise!
Thanks & Kind Regards,
Shahvir
