Study on Ethernet Communication Strategy for Electric Energy Data Acquisition System

As Ethernet technology is being matured and perfect, Ethernet also show the advantage of its application in industrial control field because of its good reliability and real-time performance. After introducing calculation method of basic power parameter briefly, the Ethernet communication strategy between smart meter and acquisition terminal in the electric energy data acquisition system is studied for the date communication requirements of energy data acquisition. The rule of data transfer regulation, and formulation method of Modbus/TCP protocol based on DLT 645, hardware design and software design of Ethernet communication interface are given. The test showed communication is stabilized, and the transmission efficiency of electric energy data meet requirement.
