随着舰船综合电力系统技术的发展，逆变电源已成为部分全电力推进舰船电力系统的主供电电源。逆变电源作为电子设备，虽然具有电能品质高、响应速度快的优势，但也存在任务可靠度低的不足。针对这一问题，本文提出一种新颖的基于冗余逆变电源切换策略的并联供电方案，分析了高任务可靠度的供电切换方法。通过电源系统的供电可靠度建模和计算，本文所提出方案在仅增加一台冗余电源的前提下，不仅提升了重要负载的供电可靠性，同时也提高了全船全网的供电可靠度。
With great development of integrated power system, inverters have been main power supply in power system for some of full electric propulsion ships. As an electronic device, an inverter has the advantages of high quality of static and dynamic state, but it also has the disadvantages of low mission reliability. A novel parallel power supplying scheme based on a redundant inverter is put forward. Besides that, a high reliable scheduling strategy is introduced in use of switching and paralleling the redundant supply. After building and analyzing a mathematic reliability model of the new supply scheme, it is proved that the reliability is improved significantly for both critical loads and common loads.
