Digital Substation

PLC Technology is actively developing and manufacturing equipment for Digital Substations (DSS). Over the long period of work, we have created our own vision of the DSS concept, and also developed a line of equipment and software for building DSSs, to implement DSS technologies in the equipment of single turnkey vendor.
MU Series Merging Units are designed to interface existing measurement current and voltage transformers with the IEC 61850-9-2 bus.
The MU series devices also support the exchange of information on the state of switching devices and the execution of commands for their control in accordance with IEC 61850-8-1 (GOOSE).
In addition, the commercially available PM7 and MTU5 series modules also support IEC 61850. The IEC 61850 standard is implemented both for the exchange of GOOSE messages and for the exchange of MMS messages for vertical communication with substation process control systems.
