Simulation Evaluation and Implementation of MPPT Control Method for All-electric Propulsion GEO Satellites
针对全电推GEO卫星任务特点,结合能源系统全调节控制架构,建立高轨太阳电池阵模型,提出一种自适应占空比的最大功率点跟踪(MPPT)电源控制方法,通过软件仿真对比分析具有代表性的 MPPT方法(扰动观察法、电导增量法)静动态参数,评估静态跟踪精度、动态跟踪响应时间以及在太阳电池阵电流突变、负载跃变后的动态响应特性等,综合参数表现优劣,选择合适的 MPPT方法,同时开展 MPPT调节器的设计与地面试验验证,为后续在 GEO全电推平台上的应用提供有效技术支撑.
To address the mission characteristics of all-electric GEO satellites,a solar array model for high-orbit applications is established based on a fully regulated power system control architec-ture.An adaptive-duty-cycle maximum power point tracking(MPPT)control method is pro-posed.Representative MPPT methods,including the perturb-and-observe method and the incre-mental conductance method,are compared through software simulation in terms of static and dy-namic parameters.Static tracking accuracy,dynamic tracking response time,and dynamic re-sponse characteristics under abrupt solar array current changes and load variations are evaluated.Based on a comprehensive comparison of parameter performance,a suitable MPPT algorithm is selected.The design and ground test verification of an MPPT regulator is simultaneously carried out,providing effective technical support for subsequent application on GEO all-electric propul-sion platforms.
