As industrial economies grow and become more efficient they also become more reliable on electricity as their main source of energy. Hence, a blackout in electrical system causes massive damage to social and economic aspects of a society. To prevent interruptions and to provide energy to electricity consumers reliably automation needs to take place at each stage of the electrical system: generation, transmission, and distribution. As each stage is automated, there has to be reliable, fast, and efficient communication amongst devices and the SCADA control center. Communication lines need to carry information and data between substations and control centers at different parts of the network so that monitoring and automation of the system can occur. Without adequate communication amongst devices SCADA system will render itself useless and will not be able to provide the reliability and efficiency needed in today’s electricity markets. It is also important to note that automation in electrical systems allows for the system control and operator to define specific performance and protection parameters, which will lead to consistency across the electrical grid. Legacy substation automation protocols and architectures typically provided basic functionality for power system automation and were designed to accommodate the technical limitations of the networking technology available for implementation. IEC61850 is an important new international standard for substation automation that will have a very significant impact on how electric power systems are designed and built for many years to come.
