Design of intelligent concentrator in the power information gathering system

In the context of smart grid, intelligent concentrator in the power information gathering system has become the development trend. In this paper, The structure and function of the power information gathering system are analyzed, and then it presents hardware design of the concentrator based on DTT6C01B chip. Original Q/GDW 376.1 and 376.2 protocol standard are expanded to realize the functions of data acquisition and control of smart appliances and charge piles. The concentrator supports McWiLL standard for uplink communication and WIA standard for downlink, which can meet the requirements of reliability end high efficiency in the data acquisition. The design of the concentrator provides a good reference design platform for the development of smart power.
