Why Choose Diesel Generator
In modern life, electricity has become a non-existent or missing part of life. There are many ways to generate electricity, but why should we choose a diesel generator? Here we look at the strengths of diesel generators in use!
• 1.Single machine capacity grade, convenient equipment
Diesel generator sets have a stand-alone capacity of several kilowatts to tens of thousands of kilowatts. According to their usefulness and load conditions, they have a wide range of available capacities and have the advantage of being used in a variety of capacity-based electrical loads. When a diesel generator set is accepted as an emergency and standby power source, one or more units can be accommodated, and the installed capacity can be sensitively equipped according to actual needs.
• 2. The unit power component is light and installation is sensitive
Diesel generator sets have relatively simple supporting equipment, fewer auxiliary devices, small size, and light weight. Take the high-speed diesel engine as an example, which is usually 820 kg/KW, and the steam power plant is more than four times larger than the diesel engine. Due to this feature of diesel generator sets, it is sensitive, convenient and easy to move.
The diesel generator set used as an independent power supply main power supply accommodates the independent equipment method, while the standby or emergency diesel generator sets are commonly used together with the variable distribution equipment. Since the diesel generator sets are not normally operated in parallel with the city power grid, the units do not need a full source of water [The cost of cooling water for the diesel engine is 3482L/(KW.h), which is only 1/10 of the turbine generator set, and the floor area is Small, so the installation of the unit is more sensitive.
• 3. High thermal compliance and low fuel consumption
The effective thermal compliance of diesel engines is 30% and 46%, that of high-pressure steam turbines is 20% and 40%, and that of gas turbines is 20% and 30%. It can be seen that the effective thermal compliance of diesel engines is relatively high, so their fuel consumption is low.
• 4. Start agile and can reach full power soon
The start-up of a diesel engine usually takes only a few seconds. In an emergency configuration, it can be fully loaded within 1 min. In normal operating conditions it is brought to full load within about 510 min, and the steam power plant starts from normal operation until it is fully loaded with 34 h. The shutdown process of the diesel engine is also very short and can be started and stopped frequently. Therefore, diesel generators are suitable for cooperation as emergency or backup power supply.
• 5. Easy to operate and maintain
Only the general staff who read the crew's statement carefully can start the diesel generator set and perform the usual maintenance of the unit. The unit's faults can be accepted on the machine, repairs are required, and fewer staff are required to repair and repair.
• 6.Comprehensive low cost of power plant establishment and power generation
Compared with turbines to be built, steam turbines to be equipped with steam boilers, and larger fuel preparation and water treatment systems, the diesel power station has a small footprint, a fast build-up rate, and low investment costs.
According to the statistics of relevant materials, compared with renewable power generation such as hydroelectricity, wind power, and solar energy, as well as nuclear power and thermal power generation, the combined cost of the establishment of a diesel power station and power generation is the lowest.
