Diesel generator sets in our country are nominal based on the main power, which is continuous power. The maximum power that a generator set can use continuously within 24 hours is called continuous power. During a certain period of time, the standard is that every 12 hours, there is 1 hour that can be overloaded by 10% on the basis of continuous power. At this time, the unit power is what we usually call the maximum power, which is standby power, that is, If you purchase a main 400kw unit, you can run it up to 440kw in one hour within 12 hours. If you purchase a backup 400kw unit, if you don't overload it, you usually operate it at 400kw. In fact, the unit has always been in an overloaded state because the actual rated power of the unit is only 360kw, which is very detrimental to the unit, will shorten its lifespan, and cause an increase in failure rate.

1) The unit of apparent power is KVA, which is commonly used in China to express the capacity of transformers and UPS.

2) The active power is 0.8 times the apparent power, measured in kilowatts, and is commonly used in power generation and consumption equipment in China.

3) The rated power of a diesel generator set refers to the power that can operate continuously for 12 hours.

4) The maximum power is 1.1 times the rated power, but only 1 hour of use is allowed within 12 hours.

5) The economic power is 0.5 or 0.75 times the rated power, which is the output power of a diesel generator set that can operate for a long time without time constraints. At this power, fuel is the most economical and the failure rate is the lowest.
