摘要
船舶轴带电机能够充分利用主柴油机的富裕功率,达到节能减排的作用。相较于传统的逆变器,Z源逆变器能同时实现升/降压功能,且电路结构简单,控制方便。在船舶轴带发电机系统结构的基础上,详细论述了Z源逆变器的结构和工作原理,并结合并网PQ控制策略,实现对船舶轴带电机系统的控制。通过Matlab/simulink仿真波形,可知基于Z源逆变器和并网控制策略船舶轴带发电机系统可以输出需要的电压和电流,进一步验证了所提控制策略的正确性和可行性。
The marine shaft generator can make full use of the rich power of the main diesel engine to achieve the aim of energy conservation and emissions reduction. Comparing to the traditional inverter, the Z-source inverter can be used for boosting and bucking and the circuit structures are simpler and its control is easier. On the base of analyzing the structure of the marine shaft generator, the structure and operating principle of the Z-source inverter are discussed in detail. Andcombin-ing with the grid-connected control, the control of the marine shaft generator system are realized. Finally, the control strategy is verified by means of simulation in Matlab/Simulink.
