How to choose diesel generator set?

There are many kinds of generator sets on the market, such as gas turbine generator sets, diesel generator sets, hydroelectric generator sets, and wind generator sets. Different types of generator sets have different performances, the scope of use, market conditions, etc., so generator sets should be selected reasonably.

The Several factors should be considered when selecting diesel generator sets

Mainly include the mechanical and electrical performance of the diesel generator set, the purpose of the diesel generator set, the capacity and variation range of the load of the diesel generator set, the use of environmental conditions of the diesel generator set (including altitude, climatic conditions, noise), automation functions, etc. Since diesel generator sets can be used in three situations: common, standby, and emergency situations, the requirements for diesel generator sets are different for different purposes.

 

The Selection of commonly used diesel generator sets

(1) Determination of diesel generator set capacity: According to the long-term continuous operation of the diesel generator set, the output power can meet the maximum calculation load selection of the whole project, and the spare set capacity of the generator set should be determined according to the importance of the load. The continuous output power of the diesel engine is generally 0.9 times the calibrated power. 

(2) Determination of the number of diesel generator sets: generally set at more than 2 sets to ensure the continuity of power supply and adapt to changes in the power load curve. When the number of units is large, the number of diesel generator sets can be determined according to the changes in electricity load, so that the diesel engine is often operated under economic load to reduce fuel consumption and reduce power generation costs. The best economical operating state of the diesel engine is between 75%-90% of the rated power. In order to ensure the continuity of the power supply, the common diesel generator set itself should be considered to be equipped with a backup set. (3) Determination of the speed of diesel generator set: Generally, high-speed generators with a speed of 1000-1500 rpm should be selected for civilian use, and low-speed generators with a speed of 300-350 rpm are suitable for marine main engines. (4) Determination of diesel generator set voltage: The determination of generator output voltage is the same as that of emergency generator set, generally 400V and some projects with large electricity consumption and the long transmission distance can choose high-voltage diesel generator set.

Selection factors of diesel generator set

Mainly include the mechanical and electrical performance, the purpose of the unit, the capacity, and range of load, the environmental conditions of the unit (including altitude, climatic conditions, noise), automation functions, etc. Since diesel generator sets can be used in three situations: common, standby, and emergency situations, the requirements for diesel generator sets are different for different purposes.
