Categorized by use
1) commonly used units
This type of generator sets run year-round, generally located in areas far from the power grid (or utility) or near industrial and mining enterprises to meet the construction of these places, production and living electricity. In areas of rapid economic development, due to the construction of the power grid can not keep up with the needs of users and set up a short construction period of commonly used diesel generator sets to meet the needs of users. This type of generator sets are generally larger capacity, non-constant load to provide continuous power supply, there is no restriction on the time of continuous operation, and allows every 12h within 1 h overload power supply time, overload capacity of 10% of the rated output power. This type of unit is adjusted to a lower point in relation to the permitted power relative to the limit power of the machine due to its longer operating time and heavier load.
2) standby unit
Under normal circumstances, the user needs power supplied by the utility, when the utility power limit pull the gate or other reasons for interruption of power supply, to ensure that the user's basic production and life of the generator set set. This kind of generator sets are standing in the telecommunication department, hospitals, industrial and mining enterprises, airports and television stations, and other important power-using units with a tight supply of utility power. This type of unit at any time to maintain a standby state, can provide continuous power supply to non-constant load.
3) Emergency unit
The sudden interruption of utility power will cause large losses or personal accidents in the power equipment, often set up emergency generator sets for emergency power supply to these devices, such as high-rise buildings, fire systems, evacuation lighting, elevators, automated production line control systems, important communication systems and patients are doing important surgical procedures with the medical equipment, etc.. This type of unit should be able to sudden interruptions in the utility power, can quickly start running, and in the shortest possible time to the load to provide stable AC power to ensure timely power supply to the load, the degree of automation of this unit requires a higher degree.
