@sophiecentaur @jim hardy I have a lot of respect for the power industry and I see an enormous wave of change coming as renewables gain ground. I am curious about how the transition will bring new challenges to it. What could be the emerging areas of research influenced by the foray of renewables?

I see. That makes things a lot clearer to me. I'm not getting into the calculations but on a rough approximation, I understand that the currents in the secondaries of both transformers will adjust themselves in such a manner (assuming the phases are in sync, for now) that the voltage at the...

Only considering practical situations here. You've partially answered another of my doubts in this reply. The load sharing will be as you say, dependent on the alternator regulators. What about transformers though?

Yes of course, considering both phase and magnitude.

Oh thanks for the update. So if two different sources energise the bus, the source at a lower voltage will draw current instead of actually acting as a source, though the amount of current would be proportional to the voltage difference. I think this will be the correct representation of the...

I'm talking about substation level, say 415V or 6.6kV switchboards. I'm more interested in how the system would behave electrically and be affected by such a configuration. I do understand the safety concerns which you mentioned. It is certainly a good point.

Even though its possible to keep a bus charged from more than one AC voltage sources, what can be the consequences of doing so? My thoughts: - Assuming thst both the sources have similar (but not equal) phase and magnitude, we can expect small circulating currents. Which brings into question the...

What can I do to accelerate the motor?

Thanks for the explanation about the ultracapacitor. It was really helpful. :)

I see. Can you help me understand the real purpose of using the capacitors? I was planning to simply control the dc motor with a chopper circuit without introduction of capacitors but the problem that arises is quick drain of the battery. I have another doubt. Will the motor consume more...

I took the schematic from a presentation that was prepared by MIT students so I don't have doubts about it. However I cannot understand the function of this circuitry. Here's the link to the presentation :- http://web.mit.edu/first/kart/everpres.pdf

There's a diode in parallel with the capacitor. Actually I was searching for a way to increase the acceleration of the motor. According to me, the speed controller will determine that but my teammate insisted that capacitors are used to increase the acceleration of motors and he also found out...

I need to determine the capacitance for a capacitor that I will be connecting in series with a DC series motor to control the current drawn from the battery by the motor. How should I proceed? I have attached the schematic.
