What engine size is needed fo 20kw generator?
Have a look at AuroraGenerators.com If it is diesel your looking at about 1 gallon per hour however likely you are not running at full load. You can expect to be using on average 0.5 gallons per hour on an Aurora Diesel Generator
Would a defective governor cause a generator motor not run?
Yes, if the governor failed in a way that "makes it think" the generator is always running too fast it might prevent the generator from running at all.
Why steam turbine speed is kept constant in power plants?
Well, the steam turbbine is most likely connected to an A/C generator which gives off the same frequency as the grid, so by running the turbine on a fixed frequency you don't have to condition the electricity before it can be released onto the grid.
What is meant by free running frequency in phase locked loop?
The VCO is a special type of oscillator that has a frequency controlled by an applied voltage.The frequency of the VCO without any control signal applied is called the free running frequency.
How do you convert 120 v 60 Hz generator to 100 v 50 Hz as in how to use an American made generator in Eastern Japan?
Try running the generator at lower rpm by adjusting engine speed. If 120v 60hz generator is designed for 1200 rpm, then try running it at 1000 rpm.
Why must the oncoming generator on a power system be parralleled at a higher frequency than that of the running system?
If the frequency of the oncoming generator is slightly higher than the system frequency, the phase angle between the system and generator voltages will slowly change at a frequency equal to the difference between system and generator frequencies.
What conditions are necessary for paralleling two synchronous generator?
•The RMS line voltages of the two generators must be equal.••The two generators must have the same phase sequence.••The phase angles of the two a phases must be equal.••The frequency of the new generators, called the oncoming generator, must be slightly higher than the frequency of the running system.
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
What is the effect on a steam turbine if the system is running in under frequency?
It results in reduced ventilation and affect the turbine more than the generator.

What does paralleled mean?
Parallel means running in exactly the same direction,and will NEVER intersect.
How much does it cost to run a diesel generator?
The cost of running a diesel generator can vary depending on various factors such as the size and efficiency of the generator, the price of diesel fuel, and the duration and frequency of usage. On average, diesel generators consume about 0.5 to 1 gallon of diesel fuel per hour for every kilowatt (kW) of power produced. To calculate the cost, you would need to know the current price of diesel fuel, the generator's fuel consumption rate, and the number of hours the generator will be running. By multiplying these factors together, you can determine the approximate cost of running a diesel generator.
Would a defective governor cause a generator motor not run?
Yes, if the governor failed in a way that "makes it think" the generator is always running too fast it might prevent the generator from running at all.
How is running water electricity?
Running water can turn a turbine that runs a generator.
What is cumulative frequency?
Cumulative frequency is the running total of class frequencies.
Why steam turbine speed is kept constant in power plants?

What is the functions of synchronous?
The light system of paralleling generators has lamps hooked in series and connected between the hot lead of the lead generator and the hot lead of the lag generator. When one generator is running faster than the other one, the lights will blink off and on as the generators come in and out of phase with each other. Adjusting the throttle of the lag generator and bringing it closer to synchronise speed will cause the lights will start to pulsate slower and slower until they go off for a period of seconds and then on for a period of seconds. At this point the two generators are electrically paralleled. Count the time between on off on of the lights. At half the off time (zero voltage) throw the switch and the generators will lock together, the two generators will be running in parallel with each other. Manually to keep them paralleled requires a bit of work, as the faster generator will try and take the load and motor the other one. This is where a governor is a great asset. If the generators are tied together out of phase two things could happen. The least problematic would be the generators breaker will trip. The second and most dangerous is if the lag generator is just a little bit out of phase when the switch is thrown, then the generator will be jerked into phase lock as momentary heavy current flows between the two generators. The sudden loading of the generator has been known to break crankshafts of the engine driving it.
