First, bring your own power supply. Some power users do not have grid power supply, such as islands far from the mainland, remote pastoral areas, rural areas, military camps, workstations, radar stations and so on. , need to be equipped with their own power supply. The so-called self-contained power supply is the self-used power supply. Under the condition of low power generation, 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 reliable power supply, emergency power generation can still be configured in order to prevent unexpected situations, such as circuit failure or temporary power failure. Power users who use electricity generally have higher requirements for power supply security, and even minute power outages are not allowed. They must use self-provided electricity to generate electricity at the moment when the power supply of the power grid stops, otherwise it will cause huge losses in the region. Such units include some traditional high power supply units, such as hospitals, mines, power plants, factories using electric heating equipment, etc. In recent years, network power supply has become a new growth point of standby power demand, such as telecom operators, banks, airports, command centers, databases, highways, high-end hotel office buildings, high-end restaurants and entertainment places. Due to the adoption of network management, these units are increasingly becoming the main body of standby power supply.
Third, alternative power supply. The function of standby power supply is to make up for the shortage of grid power supply. There are two possible situations. First, the electricity price of the power grid is too high, and diesel generators are selected as alternative power sources from the perspective of cost saving; On the other hand, in the case of insufficient power supply in the power grid, the use of power in the power grid is restricted, and the power supply department has to switch off power everywhere. At this time, for the normal production and work, power users need to replace the power supply to provide relief. In recent years, several sales of diesel generator sets in China, such as national sales in the first half of 1980s, sales in South China in the early 1990s, and sales in East China in 2003-2004, were all caused by power shortage in countries and regions. In order to cope with large-scale power outage, various power users have purchased diesel generator sets as alternative power sources.
Fourth, mobile power supply. Mobile power supply is a kind of power generation facility that has no fixed place to use and is transferred everywhere. Diesel generator set has become the first choice for mobile power supply because of its portability, flexibility and easy operation. Mobile power supply is generally designed in the form of power supply vehicles, including self-supplied trams and trailer power supply vehicles. Most power users who use mobile power supply have the nature of mobile work, such as oil fields, geological exploration, field engineering exploration, camping picnics, mobile command posts, trains, ships, power carriages (warehouses) of freight containers, military mobile weapons and equipment power supply, and some mobile power supplies have the nature of emergency power supply, such as emergency power supply vehicles in urban power supply departments, engineering rescue vehicles in water supply and gas supply departments, and emergency repair vehicles.
Fifth, fire power supply. Fire-fighting generator sets are mainly used for building fire-fighting equipment. In case of fire, the power supply is cut off, and the generator is the power source of fire fighting equipment. With the popularization of fire protection law, domestic real estate fire power supply will have great potential and 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-provided power supply and alternative power supply are the demand for electricity caused 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; Standby power supply and mobile power supply are the demands arising from the improvement of power supply guarantee requirements and the continuous expansion of power supply scope, and are the focus of market demand in the advanced stage of social and economic development. Therefore, if we look at the market use of diesel generator products from the perspective of social development, it can be said that it is a transitional use as self-provided power supply and alternative power supply, while the long-term use as standby power supply and mobile power supply, especially fire power supply, will be gradually released as a huge potential market demand.
Jiangsu Xingguang Yinchuan Branch has long provided Jiangsu diesel generator sets, Jiangsu generators, Jiangsu diesel engines and Jiangsu diesel generator sets.
