| Objective To test the low temperature environment adaptability of a high power generator set. Methods The generator set was placed in a comprehensive environmental simulation laboratory of high-low temperature. The room temperature was reduced to –55 ℃ and kept for 48 h. Then it was increased to –40 ℃ and kept for 12 h before it was restored to the normal temperature. Results The generator set started successfully in 11′20″ at low temperature. Its voltage regulation factor for continuing working at low temperature was –0.880%; its steady-state frequency control rate was –0.036%; its state voltage fluctuation rate was 0.175% and its state frequency fluctuation rate was 0.080%. No failure occurred to plastic parts, rubber articles and metal piece of the model machine. Conclusion The results show that starting performance, electrical performance, and material properties of the generator set meet the requirements on low-temperature environment adaptability. Furthermore, it provides a guidance to assess low-temperature environment adaptability of other generator set. |
