Abstract

本发明涉及电源控制技术领域，公开了基于云端数据矫正的UPS电源控制方法及系统，其中控制方法包括如下步骤：采集多个不间断电源在并联运行状态下的输出频率变化曲线、相位偏移量以及母线电流波动轨迹，在统一时间刻度下进行时序对齐比对，提取各不间断电源之间原有的微差运行区间，构建频率分散参照范围；基于频率分散参照范围，对云端下发的输出频率微调参数进行差异化拆分，将统一调整量转换为分散调整量；本发明通过构建频率分散参照范围并差异化拆分调整量，结合错时推送与渐进控制，维持分散运行状态，抑制电流叠加与误动作；同时通过动态压缩与周期性偏移轮换，降低振荡耦合风险，提升并联运行稳定性与长期可靠性。
