Intellectual control system of switching devices of high-voltage substations

The operational control systems (interlocks) of switching devices (disconnectors) are used to exclude the wrong actions of personnel during operational switching. A variant of designing an intellectual control system for switching devices using digital technologies is considered. A feature of the system is the use of inductive position sensors of switching devices. The use of specialized controllers and digital information exchange between them allows increasing the informational perfection of the system, reducing the total length of the cable network at the substation and reducing the costs of its operation. It is proposed to use standard communication protocols, including IEC 61850 to integrate the locking system into the substation automated process control system.
