(1) Diesel generators use diesel as fuel, which is fuel-efficient and has high thermal efficiency. When the working conditions change, the fuel consumption rate curve changes relatively flat.
(2) Because there is no ignition system, the failure rate is low and it is durable.
(3) It has a wide range of uses.
(4) It has low harmful emissions.
(5) It has good fire safety. The automatic voltage regulation forms of diesel generators include: thyristor, phase compound excitation, and TD1 carbon resistance automatic voltage regulation.

(1) There are many single-unit capacity levels. Diesel generator sets have different power models ranging from a few kilowatts to tens of thousands of kilowatts. The most suitable capacity level can be selected according to the usage.
(2) The supporting equipment has a compact structure and flexible installation location.
(3) It has high thermal efficiency and low fuel consumption (thermal efficiency 30~46%).
(4) The diesel generator starts quickly and can quickly reach full power.
(5) The maintenance operation is simple and easy to maintain.
(6) The comprehensive cost of construction and power generation of diesel generator sets is the lowest.
