Experimental study on dynamic characteristics of shipboard steam power system under rapid and large disturbance of generating power

  Objectives  This study seeks to explore the dynamic response characteristics of a marine steam power system under the condition of rapid and large power disturbance.

  Methods  A complete set of onshore experimental devices for a steam power system is established, and the dynamic response characteristics are studied by applying power disturbance by simulated load.

  Results  The experimental results show that under the condition of a single period disturbance, the fluctuation range of the boiler pressure is within ± 1.5% and that of the propeller speed is within ± 2.5%; under the condition of continuous periodic disturbance, the fluctuation range of the boiler pressure is within ± 2.5% and that of the propeller speed is within ± 3.5%; during the experiment, the steam power system generally runs in a stable manner.

  Conclusion  The results of this study can provide technical support for the actual operation and use of steam power systems.
