摘要

本文介绍了DDG51阿利·伯克级驱逐舰使用储能和高速发电来支持高功率负载,同时降低燃料消耗。储能器可以提供脉冲能量负载,并可以通过稳定电网来提高可靠性和电能质量。它还可以通过充当不间断电源来提高船舶效率,使单台发电机能够在接近峰值效率的情况下运行,而不是在轻负载下持续运行两台发电机组。在发生故障的情况下,储能单元为关键负载提供电力,直到第二台发电机组能够联机。基于系统建模、燃油节约预测和船舶集成研究,发现飞轮储能系统是在DDG51船舶服务发电系统上实现显著燃油节约的可行方法。使用典型的负载情况,燃油节省超过1美元 预计每艘船每年将达到百万美元。本研究的特定飞轮储能系统可以减轻系统瞬态,并提供长达10分钟的穿越时间,以实现第二燃气轮机发电机组的多次启动尝试。

Pulsed Power Loads Support and Efficiency Improvement on Navy Ships

This paper addresses the use of energy storage and high-speed power generation to support high power loads and at the same time reduce fuel consumption of DDG51 Arleigh Burke class destroyers. Energy storage can supply pulsed energy loads, and can be used to improve reliability and power quality by stabilizing the grid. It can also serve to improve ship efficiency by acting as an uninterruptible power supply, enabling single generator operation with a single gas turbine operating closer to its peak efficiency, rather than running constantly two generator sets at light load. In case of failure, the energy storage unit provides power for critical loads until a second generator set can be brought online. Based on system modeling, fuel savings projections, and ship integration studies, a flywheel energy storage system was found to be a viable approach to realizing significant fuel savings on the DDG51 ship service generation system. Using a typical load profile, fuel savings in excess of US$1 million per year per ship can be expected. The particular flywheel energy storage system of this study can mitigate system transients and provide up to 10-minute ride-through to enable multiple start attempts on the second gas turbine generator set.
