我国交会对接任务中,电源分系统实现了目标飞行器电源分系统和载人飞船电源分系统首次高低压两种体制电源分系统的联合应用。目标飞行器电源分系统为国内首个低轨高压电源分系统,突破了低轨高压防护、半刚性太阳电池翼、低轨长寿氢镍电池等关键技术,确定了电源分系统技术方案、解决了低轨高压安全性设计难题,完成了产品研制和试验验证;载人飞船电源分系统为低压电源分系统,以载人航天安全性、可靠性为设计重点,充分试验验证了多种类电源并网、多机组并网等技术。交会对接任务实践证明,电源分系统的供电能力、可靠性等各项功能指标均满足工程及系统总体要求,相关应用技术成果有助于空间站工程研制。
China’s rendezvous and docking mission, the power subsystem to achieve the target aircraft power subsystem and manned spacecraft power subsystem for the first time low voltage two system power supply system of joint application. The target aircraft power subsystem is the first low-voltage high-voltage power supply subsystem in China, breaking the key technologies of low-rail high voltage protection, semi-rigid solar battery wing and low-rail long life nickel-metal hydride battery, and has determined the technical scheme of power subsystem and solved the problems of low Rail high-voltage safety design problems, completed the product development and test verification; manned spacecraft power supply subsystem for low-voltage power subsystem to manned space safety and reliability as the design focus, fully tested and verified that a variety of power grids, Multi-unit and network technology. The rendezvous and docking mission proved that all functional indexes such as the power supply capability and reliability of the power subsystem satisfied the overall requirements of the project and the system, and the relevant applied technical achievements contributed to the development of the space station project.
