Influence Of Ambient Temperature On Power Of Diesel Generator Set

The high temperature is affecting most parts of China, which is basically in the high-temperature barbecue mode, with the highest temperature above 36 degrees Celsius. Electricity consumption in many areas is constantly breaking historical records. At this time, the power of the diesel generator set will also change with the change of ambient temperature.

Of course, the output power of the generator set is affected by many external factors, in addition to the ambient temperature, the average altitude, air humidity and atmospheric pressure, etc. have a great impact on the generator set.

Today, I introduce the influence of ambient temperature on the power of the generator set. According to the international general technical requirements, the general definition of the use of the generator ambient temperature is 40 degrees Celsius, all design and power are in accordance with this ambient temperature.

In fact, for diesel generators, the ambient temperature should be the generator inlet temperature. Because the generator is working with the diesel engine, the diesel engine will heat up in use, coupled with the high ambient temperature, so that the temperature in the whole space of the whole generator set will exceed 40 degrees Celsius.

For the environment temperature, if it is lower than 40 degrees Celsius, the power of the generator can be larger than the rated power, such as the spring and autumn winter, although the unit send out quantity of heat, but the environment temperature is lower, so it's the temperature of the surrounding space would not be more than 40 degrees Celsius, at that time, the output power of the generator set will reach normal power rating. When the ambient temperature exceeds 40 degrees Celsius, the power of the generator set will have a certain correction. When the ambient temperature exceeds 40 degrees Celsius, the specific correction coefficient of the generator set is provided as follows for your reference.

Ambient temperature (Celsius)          coefficient

      45                                                      0.97

     50                                                      0.94

    55                                                       0.91

   60                                                        0.88
