Comparison Of Power Quality Monitor Data Transmission Between Modbus Tcp/Ip And Iec 60870-5-104

With deployment of smart devices along the electrical grid key infrastructure points, communication process with regards to its volume and load on communication infrastructure needs to be described and evaluated. This article focuses on protocol Modbus TCP/IP and standard IEC 60870- 5-104 with regard to their communication structure and principles within substation connected to network by broadband over power lines modems (BPL). This paper also offers two communication scenarios over BPL network by using real substation power quality monitor. Furthermore, performance of each solution is being summed up in the discussion. Conclusion offers a convenient solution for utilization of key values transmission on limited communication channel.
