First you will need a three phase generator. Mathematically there are 746 Watts per horsepower, but I like to use 1000 Watts for ease of mental calculation. This would mean you would need a 30 kW generator. If using 746 Watts per HP, you would need 22380 Watts, or 23 kW. Make sure this 23 kW is the normal load rating of the generator, not the surge rating! 30 kW would provide more of a safety cushion.

What is single phase ac generator?
It's an electrical generator converting mechanical power into electrical power. The electrical power comes out in the form of single-phase alternating current.
Why would a generator put out 240 volt single phase?
For a home generator, to supply voltage for devices that require 220 V or 240 V. An electric oven or clothes dryer are examples of such devices. The generator at the power plant actually generates electricity at a much higher voltage, for easier transmission (and those are 3-phase generators). Also most homes run on 240 single phase. Power is split at the breaker box. To supply 120 loads and 240 loads. 240 single phase is a common voltage.
How reverse power will occur during synchronizing?
Reverse power flow into a generator can occur during synchronization if the generator is spinning too slowly, or the voltage phase angle is lagging relative to the power system. If the generator is spinning too slowly, power from the system is used by the generator to increase its' speed. If the phase angle is lagging, an initial spike of power will flow into the generator to force it into sync with the system. Typically generator's will match system frequency very closesly, and force the phase angle to leading slightly between the generator and the system. When synchronized, an extra bump of power will flow out while the generator is torqued into phase with the system. This will avoid tripping any reverse power devices.
How do you calculate 3 phase power factor?
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.
Is the kva rating of a three phase generator per phase or a total of the three phases example is a 3 phase 75 kva generator 25 kva per phase or 75 per phase?
The kV.A (not 'kva') rating is the total apparent power of the machine. So a 75 kV.A machine is 25 kV.A per phase.

Does anyone have a power generator for sale?
Yes. I have a several power generators for sale. Single phase, Three phase, Diesel and Petrol. What sort of power generator are you looking for exactly? Industrial, residential?

What is installed capacity of a power plant?
power that can be produced by generator at any insant of time
Can a 6 watt dc generator produce that much electricity which can be used to run a 3 phase and a 2 phase motor?
"2 phase" and "3 phase" are descriptions of AC supplies, which no DC generator can imitate, regardless of its power rating.
How do you convert a single phase generator to a three phase generator?
You really can't without replacing the generator end (head) with an end wound for three phase. Three phase ends are not usually made for smaller generators. Of course, once the power leaves the generator, it could be applied to a static or rotary convertor same as is used with utility power. Make sure the generator has sufficient KW to run both the load and the convertor. I agree. You can't without a converter.
Should residential backup generator in the US be single phase?
The type of backup generator should match the type of utility service you receive. If your utility power is single-phase (almost all residences in the US are), then yes, your generator should be single-phase as well.
If my house has a 200 amp line what size generator would it take to run the house and have the same power?
Your house runs nowhere near 200 amps, so you need to make a list of appliances and fixtures that you use, or that you will need while the generator is running, and add their power consumption together. Add some extra capacity for growth and so the generator is not always at full power. Then talk to dealers about generators with the amount of power you need. To run the house on a generator with the same capacity as the service that you have in your house you would need a 50 Kilowatt generator.
How do you calculate 3 phase power factor?
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.

What changes mechanical energy into electrical energy that can be transported through the power grid?
A three phase alternator (sometimes incorrectly called a generator or AC generator) is a device that changes rotational mechanical energy into electrical energy. The power grid transmits three phase electrical power (usually in Delta configuration) from electricity suppliers to local distribution systems; which then distributes the electrical power as either three phase Delta configuration, three phase Y configuration, two phase, or single phase power depending on the needs if the users.
