摘要:

针对GEO通信卫星平台电源系统的需求,完成一种基于最大功率点跟踪技术的方案设计及仿真。该方案减少了功率传输线路上电源变换器损耗,有利于最大限度地利用太阳能电池阵输出功率。在对太阳能电池阵特性研究与建模的基础上,在电源仿真软件中对电源系统进行搭建,仿真结果表明该系统可以实现对太阳能电池阵的最大功率跟踪,并维持母线电压的稳定。最后将新型方案与传统方案进行比较,给出新型方案的优势和应用前景,为电源系统的应用奠定基础。

Abstract:

According to the need of power system for GEO satellite,the plan design and simulation based on Maximum Power Point Tracking (MPPT) technology were designed and simulated.It could reduce the power loss in power transport line and made full use of the output power of solar array.Based on the research and simulation for solar array,the simulation of all the power system was fi nished.The result of simulation provides that it can complete the MPPT function and stabilize the bus voltage.Last,the new plan and the traditional one were compared,which shows the advantage of the new plan and lays a foundation for next power system.

Key words: power system, power condition unit, MPPT
