What are the main uses of diesel generator sets?
- Jul 03, 2018 -

A diesel generator is a kind of power generation equipment. Its principle is to use the engine to burn diesel, convert thermal energy into mechanical energy, and then drive the generator to cut the magnetic field through the rotation of the engine, and finally generate electrical energy. Its use mainly has the following five aspects:

First, bring your own power supply. Some electricity-using units do not have network power supply, such as islands far away from the mainland, remote pastoral areas, rural areas, barracks in the desert plateau, workstations, radar stations, etc., which need to configure their own power supply. The so-called self-contained power supply is a self-use power supply. When the power generation power is not too large, the diesel generator set is often the first choice for self-contained power supply.

Second, standby power. The main purpose is that although some power supply units have a reliable and reliable network power supply, in order to prevent accidents, such as circuit failures or temporary power outages, they can still be configured as emergency power generation units that use power. Generally speaking, the requirements for power supply protection are relatively high, and even one-second and one-second power outages are not allowed. It is necessary to replace emergency power generation at the moment of termination of power supply by network power, or it will result in large area losses. Such units include some traditional high-power supply units, such as hospitals, mines, power plant security power supplies, and factories that use electrical heating equipment. In recent years, network power has become a new growth point for standby power needs, such as telecom operators and banks. Airports, airports, command centers, databases, highways, high-grade hotel offices, high-class restaurants, entertainment venues, etc., due to the use of network management, these units are increasingly becoming the main body of standby power.

Third, replace the power supply. The role of alternative power supply is to make up for the lack of network power supply. There may be two situations. One is that the price of network power is too high, and the diesel generator is used as an alternative power source from the perspective of cost saving. The other is that in the case of insufficient network power supply, the use of network power is limited and the power supply department has to be everywhere. When power is cut off, electricity units need to replace the power supply for normal production and work. In recent years, China’s hot market for diesel generator sets has been hot, such as the national sales in the first half of the 1980s, the hot sales in southern China in the early 1990s, and the hot sales in the East China region in 2003-2004, all because of national Due to the regional power shortage, in order to cope with large-scale power cuts, all power-using units have purchased diesel generator sets for use as alternative power sources.

Fourth, mobile power. The mobile power source is a power generation facility that has no fixed place of use and is transferred around. Diesel generator sets have become the first choice for mobile power because of their lightweight, flexible and easy-to-operate features. Mobile power is generally designed in the form of a power supply vehicle, a self-powered vehicle, and a trailer-powered vehicle. Most of the electricity-using units that use mobile power sources have the nature of mobile work, such as oil fields, geological exploration, exploration of field projects, camping picnics, mobile command posts, trains, ships, freight car containers (warehouses), and army mobile weapons. Equipped with power supplies, there are also some mobile power supplies that have the nature of emergency power supplies, such as emergency power supply vehicles for urban power supply departments, engineering emergency vehicles for water supply and gas supply departments, and emergency repair vehicles.

Fifth, fire power. The fire generator set is mainly used for building fire protection equipment. Once a fire occurs, the utility power is cut off and the generator is the source of power for the fire fighting equipment. With the fire safety law, the domestic real estate fire power supply will be There is a very large market with great potential for development.

It can be seen that the four uses of the above diesel generator set are due to different stages of social development. Among them, the self-provisioned power supply and alternative power supply are the electricity demand due to the backward construction of power supply facilities or insufficient power supply capacity. It is the focus of market demand in the initial stage of socio-economic development. The standby power supply and mobile power supply are the demand arising from the increase in power supply security requirements and the continuous expansion of the power supply range. They are the focus of market demand in the advanced stage of socio-economic development. Therefore, if it is from the society, From a development point of view to examine the market use of diesel generator sets, it can be said that it is a transitional use as a self-contained power supply and alternative power supply, and as a standby power supply and mobile power supply is its long-term use, especially fire power as a potential market Demand will be released slowly.
