Diesel generator sets have the advantages of flexibility, less investment, and easy start-up. They are widely used in communication, mining, road construction, forest areas, farmland irrigation, field construction and national defense engineering. There are many types of diesel generator sets. According to the fuel classification of the engine, they can be divided into diesel generator sets and composite fuel generator sets; according to the speed classification, they can be divided into high-speed, medium-speed, and low-speed diesel generator sets. You introduce several types of diesel generator sets:
1) Commonly used units
This type of generator set operates all year round and is generally located in areas far away from the power grid (or commercial power) or near industrial and mining enterprises to meet the needs of construction, production and living in these places. In areas with relatively rapid economic development, because the construction of the power grid cannot keep up with the needs of users, common diesel generator sets with short construction periods are set up to meet the needs of users. This type of generator set generally has a large capacity, provides continuous power supply for non-constant loads, has no limit to the continuous operation time, and allows 1 hour of overload power supply time in every 12 hours, and the overload capacity is 10% of the rated output power. . Because of the long running time and heavy load of this type of unit, the allowable power relative to the limit power of the unit is adjusted to a lower point.
2) Standby unit
Under normal circumstances, the power required by the user is supplied by the mains. When the mains is cut off or the power supply is interrupted for other reasons, the generator set is set up to ensure the basic production and life of the user. This type of generator set is permanently installed in the telecommunications sector, hospitals, industrial and mining enterprises with tight mains supply, airports and TV stations and other important power-consuming units. This type of unit maintains a standby state at any time and can provide continuous power supply to non-constant loads.
3) Emergency unit
Emergency generator sets are often set up to provide emergency power supply for electrical equipment that will cause large losses or personal accidents due to sudden interruption of mains, such as fire protection systems in high-rise buildings, evacuation lighting, elevators, automatic production line control systems, and important communication systems. As well as medical equipment that is performing important operations on patients. This type of unit should be able to start operation quickly when the mains is suddenly interrupted, and provide stable AC power to the load in the shortest time to ensure timely power supply to the load. This type of unit requires a high degree of automation.
