generally the generators are synchrozised by checking three conditions
1. their terminal voltages must be the same
2.their frequencies must be same
3.their phase sequence must be same
if any one of the conditions are not satisfied and they are connected in parallel then the machines will be burnt with in a fraction of second

∙ 12y agobefore synchronizing two generators be sure that the incoming generator little bit high frequency than other generator.after that processed before turning on in synchronization be sure that the indicator light of the synchronization meter 5 mins. before twelve and that is the time to synchronize the two generator....

∙ 9y agoCoupling 2 generator in parallel isn't as easy as you think:
their voltages must have the same value, the same frequency, and the same phase (ie, the voltage signal provided by one generator mustn't be shift phased compared to the signal of the other one).
Generally, you are parallelling a generator into a larger grid. What you do is set the new generator for slightly higher voltage than the grid and slightly higher frequency than the grid, and then monitor their phase angle with a synchrometer. As the new generator comes into and out of phase with the grid, you get ready to close the breaker and at the same time be ready to close the steam bypass valves on the condenser. At the correct point, usually 12:00 leading, you close the breaker and close the bypass valve. Closing the breaker locks the generator into the grid, while closing the bypass valve forces the generator to take some load. Then you adjust the frequency of the generator to trim to the desired MVars. Yes; the generator is locked, so adjusting the frequency is actually not possible, but this does affect MVars, and you want the correct MW/MVA/MVar load on the generator as quickly as possible, to avoid destabilization and possible damage.

Is it possible to synchronize two or three generators of different KVA ratings?
Yes. In fact hundreds of generators of different sizes are run in sync with each other every day ;-) Now, it may require some special equipment, depending on how you're setting this up.
Is it possible for generators having different power factor to work together?
yes, it is possible. in fact in power systems all the generators do not run with same power factor.
When is a good time to use power generators?
A good time to use a power generator is when there is a power cut in the vicinity. power generators will provide a temporary energy source for household essentials to be run from.
Why generators are rated at 0.8 lagging power factor?
Rated power factor

Power Generators for Convenience?
Power generators convert mechanical energy to electrical energy. The many types of power generators have residential and commercial uses. Most popular of power generators is the mobile portable generator. Due to mobility, campers use portable generators for power in remote areas. Also, portable generators make power available for activities like tailgating where no electrical hookups exist. Increasingly, portable power generators are assisting homeowners in weathering storms during power outages.
What condition must be met to synchronize an alternator to an existing three-phase power line?
1.The effective voltages of the incoming generator must be exactly equal to that of the others or of the bus bars connecting them.2.The phase rotation or sequence of the running and incoming generators must be same.3. The frequency should be same.
How do you connect 2 power inverters to get 240volts?
You must synchronize the 2 inverters to have 240 the Xantrex DR4040 must have a synchronization cable. Hope that help
Why do power stations use synchronous generators and not induction generators?
This is not entirely true. In small power stations not connected to grids and wind turbines they usually use induction generators instead of synchronous for their capability of producing energy at varying rotor speeds and their price which is lower the synchronous generators. Before I tell you why they use synchronous in big power stations connected to the grid you must know that usually you have more than one power plant connected to the grid. And if you want the power of each power plant to be added to the grid you need the all the alternating currents to be in phase so the frequency must be the same. And as you probably know they are called SYNCHRONOUS generators because the speed of the rotor (the frequency) is the same as the AC supply current. So obviously it will be much easier to control the frequency of a synchronous generator and therefore easier to synchronize with the grid.
What types of small power generators are there?
There are many types of small power generators out there that save energy and money that will work just as well as larger power generators. Portable generators would be the perfect small power generator because they range from one thousand to eight thousand watts if you are using it to power your tools.
Are home solar generators as productive as a gas powered generator?
Home solar generators are usually as productive as gas powered generators. Solar panels are collecting power throughout the day and store it in batteries while gas generators are for instant power. Solar generators are more useful for long term power needs.
What is a sources of alternative fuels?
wind powered generators (power from the wind) water powered generators(power from water) solar panels (power from the sun)
I need information on solar power generators for the home.?

Where can power generators be bought from?
You can buy power generators from many different places online such as Amazon or Ebay. However, you can also purchase generators from a hardware store in your town or at a Walmart or Target.
What are uses of generators?
it can power your car
The Best Small Power Generators?
The best small power generators will be silent. The major point of using small power generators is that they can be used just about everywhere. Most people use generators like this when they are out camping or if the power goes out during a storm. In either of these situations, you don't want to worry about the noise making other people angry. This is why it's always important to look for quiet generators.
