How to Choose the Right Type of Diesel Generator Set

Jul. 13, 2021

The mechanical and electrical performance of the diesel generator set, the use of the unit, the capacity and variation range of the load, the environmental conditions of the unit (including altitude, climatic conditions, noise), automation functions, etc. are all factors that users should consider when selecting the diesel generator set.As the diesel generator set can be used in common use, standby and emergency, the requirements for different uses of diesel generator set are different. So how should the user choose the type of diesel generator set correctly? Generator manufacturers - Dingbo Power for you one by one analysis.

 

1、 Selection of standby diesel generator set.


When the sum of the load capacity multiplied by the demand factor is less than the capacity of the emergency diesel generator set, the reserve factor is considered as 1.2, that is, 1.2 times of the calculated capacity is less than the capacity of the emergency diesel generator set, and the emergency generator set supplies power to the load after the power failure.When the sum of the load capacity multiplied by the demand factor is greater than the capacity of a single emergency diesel generator set, two automatic generator sets with the same model, same capacity and similar characteristics of voltage regulation and speed regulation can be selected. In case of power failure, one or two units will supply power for domestic and commercial use; In case of power failure and fire, two units will supply power to the fire load to facilitate fire fighting.

 

2、 Selection of emergency diesel generator.


How to Choose the Right Type of Diesel Generator Set


 

Generally, the diesel generator set with high speed, supercharging, low fuel consumption and the same capacity should be selected for emergency diesel generator. High speed turbocharged diesel engine has larger capacity and occupies less space; The diesel engine is equipped with electronic or hydraulic speed regulating device, which has good speed regulating performance; The generator should choose the synchronous motor with brushless excitation or phase compound excitation device, which is reliable, low failure rate and convenient for maintenance;When the capacity of single air conditioner or motor is large in the first level load, the third harmonic excitation generator unit should be selected; The machine is assembled on a common chassis with shock absorber; A muffler should be installed at the outlet of the exhaust pipe to reduce the impact of noise on the surrounding environment.

 

3、 Selection of common diesel generator set.

 

The common generating units have a long working time, the load curve changes greatly, and the selection of unit capacity, number, type and control mode are different from emergency generating units.
