Through analysis of the working principle and advantages of EPON and in relation to smart substation’s requirements on EPON,this paper presents an implementation of EPON in the network frame of a smart substation.Through a simple analysis of the types and flow of network messages of the smart substation,it proves that EPON can be used for the process level communication of the smart substation.Furthermore,it introduces an implementation of EPON functional plug-in based on CPU and FPGA.EPON not only reduces the quantity of switches in the active fiber-optic network of the smart substation and the cost,but also improves the reliability and flexibility of the network,thus enabling easier maintenance and management of the in-station communication network.
