When ac generators are operated in parallel frequency and voltage must be equal or frequency and voltage must equal amperage?
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.
What else can I help you with?
Why shaft generator can not operate in parallel with auxiliary generator?
Normal shaft generators do not have droop-control for frequency and voltage. Semiconductor (drive) based variable speed shaft generators may have those today.
What causes generators in parallel with same voltages and KW to have different amps?
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.
Describe the procedure for paralleling the ships alternators or generators?
To parallel ship alternators or generators, first, ensure that both units are synchronized in terms of voltage, frequency, and phase sequence. Use synchronization equipment to adjust the output of each generator until they match. Once synchronized, connect the generators to a common bus, ensuring that circuit breakers are in the open position before making connections. After confirming that all parameters are aligned, close the circuit breakers to engage the generators in parallel operation.
Is this normal during a parallel of two generators where lead generator is higher in both load ampere and reactive power than the lag generator but with the same frequency same kilowatt load?
No it is not normal. Ideally both the generators share the load equally provided both generator ratings and other parameters are same.
What is parallel generator?
A parallel generator is a generator system that operates alongside one or more other generators to provide a combined power output or to share the load demand. This configuration allows for increased reliability, flexibility, and efficiency in power generation, as it can adapt to varying energy needs. In parallel operation, synchronization is essential to ensure that voltage, frequency, and phase are matched across all generators. This setup is commonly used in industrial applications, backup power systems, and renewable energy installations.
Frequency voltage and amperage must be equal when ac generators are operated in parallel?
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.
Is it feasible to parallel the dissimilar rating generators?
yes,but the two dismaler generators should have the following similarity; 1]same voltage rating 2]same frequency 3]same rpm.
Why shaft generator can not operate in parallel with auxiliary generator?
Normal shaft generators do not have droop-control for frequency and voltage. Semiconductor (drive) based variable speed shaft generators may have those today.
What happens to amperage in series and parallel circuits?
In series, Amperage remains constant. In parallel, Amperages are added.
What causes generators in parallel with same voltages and KW to have different amps?
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.
What is the procedure for paralleling the ship's generators?
To parallel ship's generators, first ensure both generators are synchronized in frequency, phase, and voltage. Use the synchronizing panel to monitor these parameters, making necessary adjustments to the speed governor and voltage regulator. Once synchronized, close the circuit breaker to connect the generators in parallel, and monitor load sharing to ensure even distribution. Regularly check for any alarms or irregularities to maintain safe operation.

What does Incoming and running generators are in same phase while paralleling two generators mean?
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
How do you parallel two generators with different kw?
To parallel two generators with different kilowatt (kW) ratings, first ensure they have compatible voltage and frequency outputs. Next, adjust the governor settings to synchronize their speeds and match the phase rotation. Connect the generators to a common busbar, ensuring the load is shared proportionally to their capacity, typically using load-sharing controllers. Finally, monitor the system for any imbalances or issues during operation.

Does battery amperage doubles when in a 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.
