提出一种变流限压式飞行器间并网供电方案,用于实现两个同电压体制飞行器间能量的可控、可靠传输。区别于国际空间站恒压限流式并网供电方案,变流限压式并网供电方法更有利于实现母线电压的稳定控制和能量的有效利用。本文分析了变流限压式并网供电方法的工作原理,通过仿真分析验证了方案的可行性,并通过搭建试验平台对并网供电的正常和极端工况进行测试验证。实验结果表明,变流限压式并网供电方案用于实现两个独立飞行器间功率并网是可行的,并网时母线电压稳定。
A scheme of grid-connected power supply between voltage-limited and pressure-limited aircraft is proposed to realize the controllable and reliable transmission of energy between two aircraft with the same voltage. Differing from the scheme of constant current and voltage limiting grid-connected power supply of International Space Station, the method of grid-connected power supply by voltage-limiting and voltage-limiting is more conducive to the stable control of bus voltage and the efficient use of energy. This paper analyzes the working principle of the VSWR-based grid-connected power supply method. The feasibility of the scheme is verified through simulation analysis. The normal and extreme conditions of grid-connected power supply are tested and verified by building a test platform. The experimental results show that it is feasible to realize the grid-connected power supply between two independent aircraft with grid-connected variable-current and voltage-limiting grid-connected power supply scheme.
