摘要

Pulsed load hybrid ships are becoming more and more widespread, but under the working condition of high-power pulsed load, it will cause great impact on ship power grid, further leading to the overall breakdown of the power system of hybrid ships. In view of such problems and the practical situation of limited space on hybrid ships and limited power grid capacity, a hybrid ship power system with high power impulse load is designed and its regular energy management strategy is studied. The ship power system can be collected quickly response of instantaneous power needed by the highpower pulse load, to have fast dynamic response characteristics of super capacitor and controllable bidirectional DC/DC converter of the combination of energy storage system, and according to the different working conditions, different rules strategy, energy management. The power system simulation model was built based on MATLAB/SIMULINK platform, and the power system without DC/DC module was compared and analyzed. The simulation results show that the voltage fluctuation range of DC bus is reduced to -3.1% ~ +0.9%, and the voltage ripple rate is reduced to 3.98%. In view of the instantaneous impact of such high power impulsive load on the power grid, the power system under this design can better smooth the instantaneous power problem and carry out energy management operation effectively.
