1. self-contained power supply
Some units without power supply, such as islands far away from the mainland, remote pastoral areas, rural areas, barracks on the desert plateau, workstations, radar stations, etc., need to configure their own power supply. The so-called self-contained power supply is the self-service power supply. In the case of low power generation, diesel generating units often become the first choice of self-contained power supply.
2. Emergency power supply
Standby power supply, also known as emergency power supply, is mainly used for emergency power generation, although some units have the relatively stable and reliable power supply, in order to prevent accidents, such as circuit failure or temporary power outage, they still configure their own power supply for emergency power generation. It can be seen that the standby power supply is actually a kind of self-contained power supply, but it is not used as the main power supply, but only as a relief means in emergencies.
3. Alternative power source
The role of the alternative power supply is to make up for the shortage of power supply. There may be two situations. One is that the price of the power grid is too high, and diesel generating units are chosen as alternative power sources from the perspective of cost saving. Another is that in the case of insufficient power supply, the use of power is limited, and the power supply department has to pull the switch everywhere to limit the power supply. At this time, in order to produce and work normally, the power unit needs to replace the power supply to relieve.
4. Mobile power supply
Mobile power is a power generation facility that has no fixed place to use and is transferred everywhere. The diesel generator set is the first choice of mobile power supply because of its handiness, flexibility and easy operation.
