柴燃联合动力装置非对称主机推进工作制的仿真研究

Simulation research on operation scheme of dissymmetrical main engine of CODOG propulsion system

    摘要
  • 摘要:
      目的  当舰船柴燃联合动力装置（CODOG）因作战而导致某台主机发生故障时，如何使其保持较好的推进性能，对于该推进系统的应急使用具有重要意义。
      方法  在Simulink环境下采用模块化建模思想构建“船—机—桨—舵”系统的仿真模型，提出CODOG双轴非对称主机推进的应急运行模式，并对该运行模式进行仿真。
      结果  仿真结果表明：若额定工况下2台主机无法同时工作，可通过调整2部调距桨的螺距使其中一台主机在额定工况运行，另一台主机则采取部分负荷运行；若要保证高航速，应使燃气轮机产生额定功率，此时柴油机对应的调距桨的螺距应保持在最大值附近；在最高航速下可达到设计航速的84.4%，舰船的快速性要优于采用燃气轮机单轴推进模式。
      结论  研究结果对CODOG动力装置的设计具有一定的参考价值。

     

    Abstract:
      Objectives  How to maintain propulsion capability in a CODOG propulsion system damage situation has important significance.
      Methods  A 'Hull-Engine-CPP-Rudder' simulation model of a CODOG marine power plant is established on Simulink using the modularized method, and a dissymmetrical main engine urgent working mode is proposed and simulated.
      Results  The results show that in the dissymmetrical working mode, two different engines cannot work simultaneously at designed capacity. However, by adjusting the pitch of the CPP, one engine can work at designed capacity and the other can work at partial load capacity; under this working mode, if high speed is demanded, the gas turbine should work at designed capacity. The CPP pitch driven by diesel should be maintained at a high value near the maximum. The maximum speed of this working mode is 84.4% of the designed speed, which is higher than the speed of the single shaft working mode driven by a gas turbine.
      Conclusions  The research results of this paper can provide useful references for the design of ship propulsion systems.
