Nov. 01, 2021

Today we will give you a brief introduction about the regulations that should be met in the selection of Volvo diesel generator sets.

The capacity and number of Volvo diesel generator sets should be comprehensively determined according to factors such as the emergency load size and the order of input, and the starting capacity of a single motor. When the emergency load is large, multiple engines can be operated in parallel, and the number of Volvo diesel generator sets should be 2 to 4. When restricted by parallel conditions, district power supply can be implemented. When the harmonics of the electrical load are large, its impact on the generator should be considered.


In the plan and preliminary design stage, the diesel generator capacity can be estimated at 10% to 20% of the total capacity of the distribution transformer. In the construction drawing design stage, the capacity can be determined according to the capacity of primary load, fire load and some important secondary loads according to the following methods:


(1) Calculate the generator capacity according to the stable load;


(2) According to the single motor or Calculate the generator capacity for the starting needs of the group motor;


(3) Calculate the generator capacity according to the allowable voltage drop of the generator bus when starting the motor.


When there is elevator load, the generator bus voltage should not be lower than 80% of the rated voltage in the case of full voltage starting capacity cage motors; when there is no elevator load, the bus voltage should not be lower than 75% of the rated voltage. When conditions permit, the motor can be started by step-down. When there are multiple Volvo diesel generator sets, select Volvo diesel generator sets and supporting equipment with the same model, specifications and characteristics.


Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
