As a power supply device, the diesel generator set can be used as a common power source or a backup power source, and its use is very extensive. The whole set of units is generally composed of diesel engine, generator, control box, fuel tank, storage and control storage battery, protection device, emergency cabinet and other components. The whole can be fixed on the basis, positioned for use, or mounted on a trailer for mobile use. The diesel generator set is a non-continuous operation power generation equipment. If it is continuously operated for more than 12 hours, its output power will be lower than the rated power by about 90%. Despite the low power of the diesel generator set, it is widely used in mines, railways, field sites, road traffic maintenance, factories, enterprises, hospitals, etc. due to its small size, flexibility, light weight, complete and easy to operate and maintain. As a backup power or temporary power supply.

 

First, bring your own power supply. Some power units do not have network power supply, such as islands far from the mainland, remote pastoral areas, rural areas, military camps on the desert plateau, workstations, radar stations, etc., you need to configure your own power supply. The so-called self-contained power supply is a self-contained power supply. When the power generation is not too large, the diesel generator set often becomes the first choice for the self-supplied power supply.

 

Second, the backup power supply. The backup power supply is also called emergency power supply. The main purpose of Yuchai generator set is that some power units have a relatively stable and reliable network power supply, but in order to prevent unexpected situations, such as circuit failure or temporary power outage, etc. Self-provided power supply for emergency power generation. It can be seen that the backup power supply is actually a kind of self-supplied power supply, except that it is not used as a main power source, but is used as a relief only in an emergency situation. The power consumption unit that uses the backup power supply generally has higher requirements for power supply guarantee. Even the power outage of one minute and one second is not allowed. It must be replaced by self-supplied power generation at the moment when the network power supply is terminated, otherwise it will cause huge losses. . Such units include some traditional high-powered security units, such as hospitals, mines, power plants, power supplies, and factories that use electric heating equipment. In recent years, network power has become a new growth point for backup power demand, such as telecom operators and banks. , airports, command centers, databases, highways, high-grade hotel buildings, high-end dining and entertainment venues, etc., due to the use of network management, these units are increasingly becoming the mainstay of standby power. In the age of the Internet, any power outage can have catastrophic consequences, so the security of the power supply is increasingly becoming the primary reason for choosing a backup power source. Third, replace the power supply. The role of the alternative power source is to make up for the shortage of network power supply. There may be two situations. One is that the price of the grid is too high, and the diesel generator set is selected as an alternative power source from the perspective of cost saving. The other is that in the case of insufficient supply of grid power, the use of grid power is restricted, and the power supply department has to be everywhere. When the power is turned off, in order to produce and work normally, the power unit needs to be replaced by a power source. Fourth, mobile power. Mobile power is a power generation facility that is not used at a fixed location and is used everywhere. Diesel generator sets are the first choice for mobile power supplies due to their light, flexible and easy to operate features. Mobile power is generally designed in the form of a power vehicle, with either a self-powered vehicle or a trailer-powered vehicle. Most of the units using mobile power have the characteristics of mobile work, such as oil fields, geological exploration, field construction, exploration, camping picnics, mobile command posts, trains, ships, freight containers, power compartments (cage), military mobile Weapons and equipment power supply, etc., there are also some mobile power sources with the nature of emergency power supply, such as emergency power supply vehicles in the urban power supply department, engineering rescue vehicles in the water supply and gas supply departments, and repair vehicles.
