Every generator has a required operating temperature. If it exceeds this temperature, the life of the generator will be significantly reduced and too high a temperature may burn the generator. Therefore, there is an allowable temperature increase for the generator. The higher the generator load (the greater the current it generates, also called the greater power), the higher the generator temperature.
When the generator coolant temperature is lower than the rated value, it means that the generator can have a larger temperature rise, so the generator can have a larger current. His efforts multiplied.
When the ambient air pressure decreases, the temperature increases and the relative humidity increases, the dry air drawn into the cylinder of the diesel engine will decrease and the power of the diesel engine will decrease. the powere of the diesel engine will increase. Then, when the ambient temperature is too low, when the temperature of the cooling water in the water tank is too low, the temperature of the lubricating oil will drop accordingly. larger when the temperature is lower, and its fluidity will become worse. This will not only increase the wear of diesel generator set parts, but also cause the increased resistance to movement and increase the mechanical power loss and efficiency. the power of the diesel generator set will decrease
