Study on Operation Mode of Satellite Solar Array Simulator

为了使太阳电池阵模拟器更真实地模拟卫星太阳电池阵在轨工作请况,首先,设计了一种易于工程实现的太阳电池阵模拟器硬件系统结构,同时为实现最大功率点运行,设计了卫星负载变换电路来实现卫星负载与太阳电池阵模拟器的阻抗匹配。其次,总结了太阳电池阵模拟器与卫星负载组成的系统的3种特性、6种工作点,分析了3种特性下系统工作点的建立过程。最后,采用太阳电池阵模拟器和卫星负载模拟器(电子负载)分别对3种特性下的系统工作模式进行了试验分析,试验结果证明了系统设计与理论分析的正确性和有效性。该设计与分析方法已在多套太阳电池阵模拟器中得到应用,使太阳电池阵模拟器与卫星组成的系统性能得到了优化。

In order that solar array simulator （SAS） simulates solar wing operation on orbit more realistically, firstly the paper designs a kind of SAS system hardware structure prone to be realized in engineering, and a kind of satellite load converter for impedance-matching between satellite load and SAS. Secondly, the paper summarizes three kinds of character and six kinds of operating point of system that SAS and satellite load constitute, and analyses the establishing process of system operating point. Finally, system operation mode under three kinds of character is ana- lyzed tentatively by using solar array simulator and satellite load simulator （electronic load）, and experiment results prove that system design and theoretical analysis are correct and valid. The design and analysis method has been applied in many solar array simulators, and has optimized performance of system that SAS and satellite constitute.
