Diesel generator set is a kind of power generation equipment. Its principle is to burn diesel through the engine, convert the heat energy into mechanical energy, and then drive the generator to cut the magnetic field through the rotation of the engine, and finally generate electric energy. Its purpose mainly includes the following five aspects:
▶ First, self provided power supply. Some power users do not have network power supply, such as islands far from the mainland, remote pastoral areas, rural areas, military barracks, workstations and radar stations on desert plateau, so they need to configure their own power supply. The so-called self-contained power supply is the power supply for self use. When the generating power is not too large, diesel generator sets often become the first choice of self-contained power supply.
▶ Second, standby power supply. The main purpose is that although some power users have relatively stable and reliable network power supply, in order to prevent accidents, such as circuit failure or temporary power failure, they can still be configured as emergency power generation. The power users who use the power supply generally have high requirements for power supply guarantee, and even power failure for a minute and a second is not allowed. They must be replaced by emergency power generation at the moment when the network power supply is terminated, Otherwise, large regional losses will be caused. Such sets include some traditional high power supply guarantee sets, such as hospitals, mines, power plants, security power supply, factories using electric heating equipment, etc; In recent years, network power supply has become a new growth point of standby power supply demand, such as telecom operators, banks, airports, command centers, databases, highways, high-grade hotel office buildings, high-grade catering and entertainment places, etc. due to the use of network management, these sets are increasingly becoming the main body of standby power supply.
▶ Third, alternative power supply. The function of alternative power supply is to make up for the shortage of network power supply. There may be two situations: first, the price of grid power is too high, and diesel generator is selected as alternative power supply from the perspective of cost saving; On the other hand, in the case of insufficient network power supply, the use of network power is limited, and the power supply department has to switch off and limit power everywhere. At this time, the power consumption set needs to replace the power supply for relief in order to produce and work normally.
▶ Fourth, mobile power supply. Mobile power is a power generation facility that is transferred everywhere without a fixed place of use. Diesel generator set has become the first choice of mobile power supply because of its light, flexible and easy operation. Mobile power supply is generally designed in the form of power vehicles, including self powered vehicles and trailer powered vehicles. Most of the power users using mobile power supply have the nature of mobile work, such as fuel field, geological exploration, field engineering exploration, camping and picnic, mobile command post, power carriage (warehouse) of trains, ships and freight containers, power supply of military mobile weapons and equipment, etc. some mobile power supplies also have the nature of emergency power supply, such as emergency power supply vehicles of urban power supply departments, engineering rescue vehicles of water supply and gas supply departments Rush to repair cars, etc.
▶ Fifth, fire power supply. The generator set for fire protection is mainly the power supply for building fire-fighting equipment. In case of fire, the municipal power will be cut off, and the generator set will become the power source of fire-fighting equipment. With the development of fire-fighting law, the domestic real estate fire-fighting power supply will have great potential to develop a very huge market.
It can be seen that the above four uses of diesel generator sets are produced in response to different stages of social development. Among them, self-contained power supply and alternative power supply are the power demand caused by backward construction of power supply facilities or insufficient power supply capacity, which is the focus of market demand in the initial stage of social and economic development; The standby power supply and mobile power supply are the demand generated by the improvement of power supply guarantee requirements and the continuous expansion of power supply scope, which is the focus of market demand in the advanced stage of social and economic development. Therefore, if we examine the market use of diesel generator set products from the perspective of social development, it can be said that as self-contained power supply and alternative power supply is its transitional use, while as standby power supply and mobile power supply is its long-term use, In particular, as a huge potential market demand, fire power supply will be released slowly.
As a power generation equipment, diesel generator set has some unique advantages: ① relatively small volume, flexible and convenient, easy to move. ② Easy to operate, simple and easy to control. ③ Energy raw materials (fuel fuel) come from a wide range of sources and are easy to obtain. ④ Less one-time investment. ⑤ Fast start, fast power supply and fast stop power generation. ⑥ The power supply is stable, and the power supply quality can be improved through technical modification. ⑦ The load can be directly powered point-to-point. ⑧ It is less affected by various natural climate and geographical environment and can generate electricity all day.
Because of these advantages, diesel generator set is regarded as a better form of standby and emergency power supply. At present, although there are many other means to solve standby and emergency power consumption, such as ups and dual circuit power supply, it can not replace the role of diesel generator set. In addition to price factors, it is mainly because diesel generator set, as standby and emergency power supply, has higher reliability than ups and dual circuit power supply.
