2. Generator Makeup – Major Components
Engine (mechanical energy)
Alternator (electrical energy)
Cubicle (control/monitor/breakers)
Governor (engine speed for frequency)
Voltage regulator and excitation system
Cooling System (heat removal)
Skid base & fuel tank
Canopy with lifting bale

3. Build-up of a generator
Engine speed
related to the frequency
AVR
related to the output voltage
AVR
First, let’s look at the build-up of a generator. Generators use diesel driven engines that provide the active power, measured in kilowatts. The engine speed is in direct relation with the frequency.
The alternator converts the mechanical energy into electrical energy which is measured in kilo volt-ampere and is connected to the engine with coupling discs.
Inside the alternator there is an AVR, automatic voltage regulator that ensures that the output voltage is stable, independent of the load demand.
Finally, attached to the alternator is a cubicle containing power connections and it is to these power connections that the customer connects his cables from his devices.
So to remember, the engine is responsible for the frequency and the alternator for the voltage.
Power connections
Engine Power = kW
Alternator Power = kVA

6. UL2200 UL 149 High Spec Standby Generators
Applicable for supplying emergency power for the duration of a utility outage. Should be applied where reliable utility power is available and may not be run in parallel with the public utility, except for closed transition transfers. Requires an ATS (Automatic Transfer Switch) or some other type of electrical switchgear.

Prime 90 kW 113 kVA 90%
Continuous 80 kW 100 kVA 80%
Prime Power is our best application!

26. AML Data

27. Generators – kW vs kVA – 3 Phase
277/480vac Wye, 120/208vac Wye, 120/240vac Delta.
kW / .8 = kVA
Standby or Prime rating
All 3 phase generators are designed for a power factor = 0.8
Example : 100 kVA alternator kW diesel engine
This means that the generator is used most optimal if the load has a power factor of 0.8
At that time both engine power and alternator power can be used at 100%

28. Generators – kW vs kVA – Single Phase
120vac, 240vac
kW = kVA
Standby or Prime rating
Single phase generators are designed for a power factor = 1.0
Example : 100 kVA alternator = 100KW kW diesel engine
This means that the generator is used most optimal if the load has a power factor of 1.0
