Characteristics of emergency backup diesel generators

Diesel generator set is a technology integrating diesel engine, generator and automatic control. Diesel generating set is a diesel engine as power generating equipment, it and commonly used steam generators, hydroelectric generating set, atomic energy, gas turbine generator unit in power generation equipment, such as with compact structure, total air volume is small, high thermal efficiency, start, swiftness, control sensitivity and fuel storage character such as lunch.

1. Multiple capacity levels.

Diesel generator set of single capacity from a few kilowatts to tens of thousands of kilowatts, is now the biggest single capacity of thousands of kilowatts, domestic unit used for ships, post and telecommunications, high-rise buildings, industrial and mining enterprises, the commonly used military equipment, emergency and standby generator capacity, large range of optional capacity, have the advantage of applicable to a variety of power load capacity. When diesel generator sets are used as emergency and backup power sources, one or more sets can be used. The installed capacity is sensitively configured according to practical requirements.

2. The supporting equipment is compact in structure and sensitive in location.

Diesel generator set matching equipment is simple, less auxiliary equipment, small size, light weight. Compared with water turbine unit which needs to build a dam, steam unit which needs to be equipped with boiler, fuel storage and water treatment system, diesel generator unit has a small air volume, fast establishment and low investment cost. The common generator set is usually configured independently, while the standby generator set or emergency generator set is usually used in cooperation with the transformer and distribution equipment. Because the unit generally does not operate in parallel with the external (municipal) power grid, the same opportunity group does not need sufficient water source [the cooling water consumption of diesel engine is 34~52L/(KW.h), only 1/10 of the turbogenerator unit], and accounts for a small air volume, so the unit location is sensitive.

3. High thermal efficiency, low fuel consumption.

Diesel engine is the highest thermal efficiency of the thermal engine, its effective thermal efficiency of 30%~46%, high pressure steam turbine about 20%~40%, gas turbine about 20%~30%. Therefore, diesel generator sets have lower fuel consumption.

4. Start fast, and can quickly reach full power.

The diesel engine usually only takes a few seconds to start, and can reach full load operation in 1min under emergency condition. Under normal operating conditions, it takes about 5 to 30 minutes to reach full load, while steam power installation requires 3 to 4 hours from start-up to full load. Diesel engine shutdown process is also very short, can frequently start and stop. So the diesel generator set is very suitable as an emergency generator set or backup generator set.

5. Simple maintenance and operation.

Less operator required, easy maintenance during the standby period.

6. the establishment of diesel generator set and the lowest comprehensive cost of power generation.

The diesel engine in the diesel generator set is usually a four-stroke, water-cooled, medium-high speed internal combustion engine. Fuel non-renewable diesel or blend it with renewable energy sources such as ethanol, biodiesel, compressed natural gas (CNG) and liquefied petroleum gas (LPG) to save energy and protect the environment. Diesel engine exhaust emissions are mainly NOx, CO, HC, PM (particles), pollution of the environment, and exhaust noise is larger. However, compared with renewable energy power generation such as water, wind and solar power, as well as nuclear power and thermal power generation, diesel generator set has a very obvious advantage: the establishment of diesel generator set and the comprehensive cost of power generation is the lowest.

Jiangsu Meiao Power Technology Co., Ltd. is an important manufacturer of diesel generators. Us ao-generator set manufacturers mainly manufacture and sell diesel generator sets, the power of generator sets is 3-3000KW, mobile station is 24-600KW, Marine emergency diesel generator set 24-800KW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, silent speaker, mobile lighthouse, container, etc.) diesel generator Group at the same time engaged in generator set maintenance and generator set accessories after-sales service.
