Medium-Speed Diesel Generator Sets refers to a power generation device that uses diesel as the main fuel and a diesel engine as the primary power source to drive an AC generator, converting mechanical energy into electrical energy. Composed of a diesel engine, an AC generator, and a control system.

Medium speed diesel generator sets are commonly used for industrial and mining power plants, peak shaving power plants, thermal power plant security power sources, and emergency generator sets for nuclear power plants. The power range of medium speed diesel generator sets is from 0.4 MW to 22.3 MW.

Characteristics of Medium-Speed Diesel Generator Sets:

1. Compared with high-speed units, the advantages of medium speed diesel generator sets are: stability (suitable for continuous operation), reliability (low failure rate), economy (fuel consumption as low as 182g/kW. h, low maintenance costs), high efficiency (power generation efficiency of over 45%), and durability (low component wear, overhaul time of 60000 to 80000 hours);

2. The disadvantage is that it is large and heavy in size, and the one-time investment cost is relatively high.
