There are many types of diesel generator sets, mainly classified into the following eight categories:
(1) According to the fuel classification of the generator, it can be classified into diesel generator sets and composite fuel generator sets;
(2) Classified by speed: it can be divided into high-speed, medium speed, and low-speed diesel generator sets;
(3) According to the classification of usage conditions, diesel generator sets can be divided into land use, marine use, trailer type, and automotive type;
(4) According to the classification of generator output voltage and frequency, it can be divided into AC generator sets and DC generator sets;
(5) According to the excitation method of synchronous generators, they can be classified into rotating AC excitation machines and static excitation machines;
(6) Classified by purpose: commonly used units, standby units, emergency units;
(7) Classified by control and operation methods: it can be divided into on-site operation generator sets, compartment operation generator sets, and automated generator sets;
(8) According to the classification of automation functions, it can be divided into basic diesel generator sets, automatic start diesel generator sets, and micro automatic control diesel generator sets.
