Portable Diesel Generators
Is this possible? Explain. Details below.?
An advertisement for a portable electrical generating unit claims that the unit's diesel engine produces 28,000 hp to drive an electrical generator that produces 30 MW of electrical power.
No it isn't possible. The output of the diesel engine is only 20.8 MW and it isn't possible for a generator to produce more power than is given to it.
The 20.8 comes from the fact that 1HP = 746W

A diesel generator is a combination of diesel engine with an electrical generator to generate electric energy.
Most people know that diesel engines in automobiles provide higher mileage, making it an obvious choice for heavy-duty transportation and equipment. Diesel is priced heavily when compared to gas, because it has a higher energy density and more energy can be extracted from diesel when compared to the same volume of gas. Diesel fuel has heavier, oilier and has a higher boiling point when compared to gas. When you compare petrol, gas and other fuels, diesel is least flammable. When compared to gas generators, this generator requires less maintenance. Being rugged and reliable, it can work for long hours at a stretch. Modern diesel generators can overcome noise issues. Onsite fuel delivery is available. These generators are used in many industries like mining, telecommunications, marine and agriculture applications, hospitals, industrial plants and commercial buildings. Although they are built for large loads, modern diesel generator is designed to comfortably handle small loads without wet stacking. These are available in single phase and there phase power generators.
You can find different types of diesel generators in the market. Small portable diesel generators range from 1kva to 10kva, while larger industrial generators range from 8kva -30kva for homes, small shops & offices up to 2000kva used for large office complexes, factories and power stations. These are used as a back up source for outdoor recreational or camping activities. Diesel generators have certain important features like: engine block is an important part of the diesel generators and the four cycle, liquid cooled model helps to improve the life of diesel generator producing less noise. There is little difference between air cooled and liquid cooled diesel generators. Air cooled engines require a tremendous amount of air. Liquid cooling offers a quieter operation and more even temperature control. There are various brands available in the market, but the wise decision would be to choose a generator from the leading brands as they come with the right configuration and warranties.
Diesel generator is most reliable and maintenance-free of all types: no ignition systems, carburetors, nor spark plugs. The fuel can be stored in large tanks; it is less flammable than other fuels and is the safest fuel to store. Diesel generators are widely used in places where grid is not available or as emergency power source if the grid fails.

The power required to run "house loads" does come from the generator. If the generator trips off line because of a protective action or because the reactor itself has shut down, then the energy comes from the grid. If the grid has failed (perhaps causing the generator to trip) then power is still possible from a second offsite source. If both offsite sources fail for some reason, then the emergency diesel generators can power the required minimal loads required to cool the decay heat from the reactor.
