FIELD: electrical engineering. SUBSTANCE: invention relates to the field of electrical equipment, in particular to the digital substations control systems. Technical result is achieved by the fact that the digital substation control system includes the substation equipment technical parameters sensors, which are connected to the data converters of such sensors into the digital form, station bus, providing information exchange between each of said converters and subsystem for generation of commands for controlling electrical substation equipment. Subsystem for generation of commands for controlling electrical substation equipment is represented by multifunctional terminals of digital substation equipped with program modules, which provide execution of control functions depending on equipment units, information from which is transmitted to terminals, wherein correspondence of equipment units to terminals is set at the level of network data transfer protocol. EFFECT: technical result consists in improvement of architecture of digital substation control system.
