2. Diesel generator - Wikipedia

   en.wikipedia.org/wiki/Diesel_generator

   A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]

3. Power-to-weight ratio - Wikipedia

   en.wikipedia.org/wiki/Power-to-weight_ratio

   A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.

4. Load factor (electrical) - Wikipedia

   en.wikipedia.org/wiki/Load_factor_(electrical)

   In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...

5. Engine–generator - Wikipedia

   en.wikipedia.org/wiki/Engine–generator

   A wattage chart can be used to calculate the estimated power usage for different types of equipment to determine how many watts are necessary for a portable generator. [4] Trailer-mounted generators or mobile generators, diesel generators are also used for emergencies or backup where either a redundant system is required or no generator is on-site.

6. Short circuit ratio (electrical grid) - Wikipedia

   en.wikipedia.org/wiki/Short_circuit_ratio...

   In an electrical grid, the short circuit ratio (or SCR) is the ratio of: the short circuit apparent power (SCMVA) in the case of a line-line-line-ground (3LG) fault at the location in the grid where some generator is connected, to: the power rating of the generator itself (GMW).

7. Power plant efficiency - Wikipedia

   en.wikipedia.org/wiki/Power_plant_efficiency

   To express the efficiency of a generator or power plant as a percentage, invert the value if dimensionless notation or same unit are used. For example: A heat rate value of 5 gives an efficiency factor of 20%. A heat rate value of 2 kWh/kWh gives an efficiency factor of 50%. A heat rate value of 4 MJ/MJ gives an efficiency factor of 25%.
