Frequency and voltage, yes. Amperage - desirable but not mandatory. Paralleled generators that are equally sized generally have a load balancing control that accomplishes this function. Generators that are of different ratings may be loaded to different current levels because of their capacity limitations.
If L1 is parallel to L2 and L2 is parallel to L3 then L1 is parallel to L3.
A structure that is parallel.
No, never. Parallel lines are line that will NEVER intersect.
Non-parallel lines intersect at some point, parallel lines don't.
There are no parallel lines in a triangle.
This question is worded awkwardly, but, the answer would be, They must be of equal Voltage (primarily) and equal frequency. If they were of different voltages, one would feed the other. The amperages can be different. If these generators were going into a distribution unit, the DU would have to have a frequency matcher, and would also force the output voltage to meet the load voltage (in the case of minor voltage deviations). Can you rephrase this question into several smaller questions? I'll help you out as much as I can from there, and go to "MY Bio Page" and ask other more detailed questions.
yes,but the two dismaler generators should have the following similarity; 1]same voltage rating 2]same frequency 3]same rpm.
Normal shaft generators do not have droop-control for frequency and voltage. Semiconductor (drive) based variable speed shaft generators may have those today.
In series circuits, amperage is the same at all points along the circuit. In parallel circuits, the total amperage is equal to the sum of the currents flowing through each branch.
If they are at the same voltage, and the same kW, the only thing left that will influence the output amperage is the power factor the generator is running at.
When two generators are to be run in parallel, one generator is first started and some load is given. Then second generator is brought in parallel with the running generator (subject few conditions, like voltage, frequency, phase angle). First generator which is running is known as running generator, the second generator which gets connected is known as incoming generator
List out the conditions to be satisfied for running two or more DC shunt generators in parallel?
Yes, and when in series the voltage doubles.
No it is not normal. Ideally both the generators share the load equally provided both generator ratings and other parameters are same.
Yes it can
What is frequency of parallel resonance formula?
Restate your question. Generators don't run in series. Generators always run on parallel synchronizing so your question is wrong.
