High Voltage DC Power Supply and Distribution System Based on Parallel Power Supply Technology

针对目前战车供配电系统动态特性差、瞬时供电能力不足的问题,设计了一种基于并网供电技术的高压直流供配电系统,采用直流微电网稳定控制技术和高压软启动技术,实现了发电机组与储能单元的并网供电,具有动态响应快、供配电简单高效等优点。试验结果表明该系统既匹配了战车上的突加突卸负载,又降低了发电机组的额定功率,提高了战车供电的可靠性,具有较好的实用性。

In order to solve the problems of poor dynamic characteristics and insufficient instantaneous power supply of current combat vehicle power supply and distribution system,a high voltage DC power supply and distribution system based on parallel power supply technology is designed.The system uses DC microgrid stabilization control technology and high voltage soft start technology to realize the grid power supply of generator sets and energy storage units.The system has the advantages of fast dynamic response,simple and efficient power distribution.The test results show that the system not only matches the sudden loading and unloading of the combat vehicle,but also reduces the rated power of generator sets,and improves the power supply reliability of the combat vehicle,and has good practicability.
