Power systems are currently complex power grids, including a large number of substations and an extensive network of power transmission lines. These lines are key components of networks and must be secured to ensure the integrity and reliability of the system. The control and protection of equipment at the substation has evolved from manual to hardware-automated, to dispatcher control and data acquisition with intelligent electronic devices enabled, and finally now to digital automation. The current substation automation standard adopted worldwide is International Electrotechnical Commission (IEC) Standard 61850.
