住宅直流供电技术的发展与前景

Advance in Residential DC Supply Technology

介绍在住宅中实施直流电力的背景和技术发展现状,指出住宅直流供电技术发展呈现几个特征:采用高、低双电压供电方式,前期将采用交流一直流混合供电方式;直流供电技术使得蓄电池、太阳能光伏发电装置以及燃料电池装置的优势得以充分挥发;住宅内各种家电的网络化系统管理是住宅直流供电技术的重要内容。直流家电的发展关键并非用电器具的技术,更重要的是住宅直流供电技术的配电技术以及电力、能源管理等技术的配套。

Brief introducing the implementation of DC supply in a residential background and technology development status,point out that residential DC supply technology development presents several characteristics;high and low dual voltage power supply,the use of AC-DC hybrid supply in early;DC technology makes the advantages of batteries,photovoltaic device and fuel cell can be fully play to the role of the functions; while household appliances LAN is an important residential DC supply technology subject.The key to the development of DC appliances technology are not appliances design and development,but more importantly,integrated into other technologies such as residential DC power supply,power distribution,power and energy management and so on.
