楼宇交直流混合供电模式下直流电压等级的研究
Research on DC Voltage Level of Hybrid AC/DC Building Power Supply System
摘要
Abstract
Although DC supply has many advantages compared to AC supply,some factors,such as,investment costs,DC interruption technology and ordinary users' habit,prevent DC supply technology from fully replacing AC in intelligent building power supply system,and that's why hybrid AC/DC supply is more feasible in short-term future.Based on the present situation,the following problems were discussed:the framework of hybrid AC/DC power supply system in future building,the corresponding AC and DC loads division,and selection principle of DC voltage level.The specific methods to determine the low DC voltage level and extra-low DC voltage level in building power supply system were introduced.In addition,the reasonable upper limit and lower limit of the two levels were made clear after the overall consideration of different factors,which can provide reference for setting the Chinese technical standard about the DC power supply voltage level.关键词
