It is so important for marine turbocharger unit to maintain a reasonable ratio of wind to fuel oil
ensure normal combustion and avoid surge in the compressor in the process of rapid load reduction. A simulation model consisting of supercharged boilers and turbocharger unit was built. The response pattern of marine turbocharger unit in different reduction amplitude of load was researched. The simulation results show as follows. The load of the power system is reduced from 100% to 20%
the bypass valve is continuously opened for approximately 5 s to exhaust excess air. In the process of rapid load reduction
the greater the amplitude of the load reduction
the smaller the surge margin of the compressor and more likely the compressor is to surge. The lower the final stable load of the system
the smaller the surge margin of the compressor and more likely the compressor is to surge.
