What are the main uses of diesel generators?

What are the main uses of diesel generators?

Diesel generator is a kind of power generation equipment. Its principle is to convert heat energy into mechanical energy by burning diesel oil through the engine, and then drive the generator to cut the magnetic field through the rotation of the engine, and finally generate electricity. Its use mainly has the following five aspects:
First, as a self-use power supply. Some electricity companies do not have network power supply. For example, islands far away from the mainland, remote pastoral areas, rural areas, military camps, workstations, and radar stations in desert plateaus need to be equipped with their own power supplies. Self-use power supply is the power supply for personal use. In the case of low power generation, diesel generator sets are often the first choice for power supply.

Second, as a backup power source. The main purpose is that some electricity companies have relatively stable and reliable grid power supply. However, in order to prevent unexpected situations, such as circuit failure or temporary power failure, it can still be configured for emergency power generation. Electricity companies that use power generally have relatively high requirements for power supply security, and even any power outages are not allowed. They must use self-emergency power generation as soon as the network power is terminated, otherwise it will cause major losses in the district. Such units include some traditional high power supply guarantee units, such as hospitals, mines, power plants, and factories that use electric heating equipment. In recent years, network power has become a new growth point in the demand for backup power, such as telecommunications operators and banks. , Airports, command centers, databases, highways, high-grade hotel and office buildings, high-end dining and entertainment venues, etc., due to the use of network management, these units are increasingly becoming the main body of backup power.

Third, as a replacement power supply. The role of the replacement power supply is to make up for the lack of network power supply. There may be two situations. One is that the price of grid power is too high, and diesel generators are selected from the perspective of cost saving; the other is that when grid power is insufficient, the use of grid power is restricted and the power supply department has to pull everywhere. Power cuts. At this time, in order to produce and work normally, the electricity user needs to replace the power source for relief. China’s recent hot sales of diesel generator sets products in the market, such as the national hot sales in the first half of the 1980s, the hot sales in South China in the early 90s, and the hot sales in East China from 2003 to 2004, are all due to national and Due to the regional power shortage, in order to cope with the large-scale power cuts, various power users have purchased diesel generator sets for replacement.

Fourth, as a mobile power source. Mobile power is a power generation facility that has no fixed place of use, but is transferred everywhere. Diesel generators have become the first choice for mobile power sources due to their lightness, flexibility and easy operation. Mobile power is generally designed as a form of power supply vehicles, there are self-powered vehicles, and trailer-powered vehicles. Most of the power consumers using mobile power have the nature of mobile work, such as oil fields, geological prospecting, field engineering exploration, camping picnics, mobile command posts, trains, ships, freight container power compartments, military mobile weaponry power supplies, etc. . There are also some mobile power sources that have the nature of emergency power sources, such as emergency power supply vehicles of urban power supply departments, engineering rescue vehicles and emergency repair vehicles of water and gas supply departments.

Fifth, as a fire power source. Fire-fighting generator sets are mainly used for building fire-fighting equipment. Once a fire occurs, the mains power is cut off, and the generator is the power source for fire-fighting equipment. With the spread of fire protection laws, domestic real estate fire-fighting power will be A very large market with huge potential for development.

The above five main uses of diesel generators are produced according to different stages of social development. Among them, self-use power supply and replacement power supply are the electricity demand generated by the backward construction of power supply facilities or insufficient power supply capacity, which is the focus of market demand in the early stage of social and economic development. The standby power supply and mobile power supply are demand generated due to the increase in power supply guarantee requirements and the continuous expansion of power supply range, and are the focus of market demand in the advanced stage of social and economic development. Therefore, if you look at the market use of diesel generator products from the perspective of social development, it can be said that it has transitional use as a self-use power supply and an alternative power supply, while it has a long-term use as a backup power supply and mobile power supply, especially fire-fighting power supply. Will become a huge potential market demand.
