Abstract

Non- renewable resources are depleted dramatically and carbon footprint are steadily increasing, causing global warming and deficiency of non-renewable resources. Solutions of power saving are needed to reduce the power usage and utilize of renewable energy. Renewable power sources can be used to power up AC or DC loads, but performance of renewable power is unstable due to the environmental issue. A multiple input power sources UPS (Uninterrupted Power Supply) system is needed to maintain the On-state of the attached load by switching load's power sources from one type to another based on the priority and availability of multiple input power sources. Two solutions are proposed in this paper to cooperate with each others to utilize the UPS function with renewable power sources. They are active and passive solution. For active solution, system performing power switching function from one type of power source to the other based on the different of power source priority. Monitoring of all the input power sources is needed in order to perform power switching. Strategy of passive solution is integrating one or more renewable power resources with the system in order to power up the attached load by using green renewable energy.

多电源自动开关监控系统的研制

不可再生资源急剧枯竭，碳足迹不断增加，导致全球气候变暖和不可再生资源短缺。为了减少电力使用和利用可再生能源，需要节能的解决方案。可再生能源可以用来为交流或直流负载供电，但由于环境问题，可再生能源的性能不稳定。多输入电源UPS (Uninterrupted power Supply)系统需要根据多输入电源的优先级和可用性，将负载的电源从一种类型切换到另一种类型，以保持附加负载的导通状态。本文提出了两种方案，相互配合，利用可再生能源的UPS功能。它们是主动和被动的解决方案。对于有源方案，系统根据电源优先级的不同，从一种电源切换到另一种电源。为了进行电源切换，需要对所有输入电源进行监控。无源解决策略是将一种或多种可再生能源与系统集成，利用绿色可再生能源为附加负荷供电。
