Why not allow the diesel generator set to run for a long time with the rated power below 50%?

This will lead to the increase of fuel consumption of diesel generator sets, easy oil leakage and carbon deposition of diesel engines, increased failure rate and shortened overhaul period.

Diesel generator set consists of diesel engine and synchronous alternator. The whole diesel generator set is mainly divided into three parts: diesel engine, generator (electric ball) and controller.

The maximum allowable power of diesel engine is limited by the mechanical load and thermal load of parts. The diesel engine should not be used beyond the rated power, otherwise the service life will be shortened and even accidents will occur.

Main applications

(1) daily power supply

Although the power of diesel generator set is low, it is widely used in mines, railways, outdoor fields, road traffic maintenance, factories, enterprises, hospitals and other departments because of its small size, flexibility, portability, complete facilities and convenient operation and maintenance.

(2) Emergency power supply

Diesel generator sets are used as emergency power supply in places that are not connected to the power grid, or when the power grid fails, and in more complex applications, such as peak shaving, power grid support and power grid output.
