| 摘要: |
| 能量平衡是微纳卫星电源系统设计和考核的重要要求，在地面通常通过数值仿真进行评价。介绍单板纳星电源系统结构和特点；分别对太阳电池阵、蓄电池组和卫星负载进行数学建模；结合卫星姿态动力学进行能量平衡仿真，仿真结果可以实时反映卫星的功率变化、电池容量和能量平衡情况。电源系统在轨试验数据与仿真结果基本一致，证明所建模型是正确的，仿真方法有效。 |

| Abstract: |
| Energy balance is the basic requirement in designing and evaluating the power system of nano-satellite, and it is often examined by numerical simulation on ground. The architecture and feature of the board nano-satellite power system was introduced first. Then the mathematical models of solar array, Li-ion battery and satellite load were developed respectively. At last, the energy balance was simulated by combining the satellite attitude dynamics. The simulation result can reflect the power change, battery capacity and state of energy balance in real time. The data of on-orbit experiment is consistent with the simulation results, which show that the models are correct and the simulation method is feasible. |
