Highland Influenceon Generator Cooling
When the generator recovers power at high altitude, the mechanical and thermal loads increase, especially the thermal load, which is the main factor limiting the power of the plateau diesel generator.
As altitude increases, air pressure decreases, and the boiling point of water decreases. Water cooled diesel generators often affect their operation due to the "boiling" of the water tank. On the one hand, due to the decrease in the concentration of the combustible mixture, the combustion speed slows down, resulting in a post combustion phenomenon, an increase in exhaust temperature, and an increase in thermal load. On the other hand, as the air density decreases, the mass flow rate of the fan decreases, and the cooling effect of the diesel generator set becomes worse. Excessive heat load not only reduces the performance of diesel generator sets, but also easily causes cylinder pulling.
Therefore, diesel generators should not only control the thermal load generated by combustion, but also control the temperature rise caused by the cooling system.
