空间太阳能发电站拓扑架构及能量管理控制策略

针对超大功率空间太阳能电站(SSPS),提出了一种分布式+集中式系统拓扑架构,将系统电力传输分为太阳电池阵区、主结构电力传输区及发射天线阵区三大部分。根据系统三大阵区的能量流动关系,本文将SSPS系统的工作模式划分为最大功率点跟踪(MPPT)工作模式、跟踪功率指令工作模式及阴影区工作模式,并提出分层能源管理控制策略。最后,针对兆瓦级太阳电池阵的不同工作模式,利用Matlab/Simulink搭建空间太阳能电站系统仿真模型,进行仿真试验及对比分析,试验结果验证了拓扑架构的合理性及控制策略的有效性,为解决空间太阳能发电技术电力传输与能量管理问题提出了新思路。

Topology Architecture and Energy Management Control Strategy of Space Solar Power Station

This paper proposes a distributed & centralized system topology structure for space solar power station (SSPS), which divides the power transmission and management into three parts, i.e. solar cell array, main structure power transmission area, and transmitting antenna. According to the energy flow relationship of the three arrays of the system, this paper divides the working modes of the SSPS system into three modes, focusing on the maximum power point tracking (MPPT) working mode, tracking power command working mode, and shadow area working mode of the SSPS solar cell array, and proposes a hierarchical energy management control strategy. Finally, for the megawatt level solar arrays with different working modes, the simulation model of SSPS system is built by Matlab/simulink, and the simulation test and comparative analysis are carried out. The experimental results verify the effectiveness of the model and control strategy to solve the space solar power generation. New ideas are proposed for solving the problem of power transmission and energy management of space solar power technology.
