Kalkitech Mercury Gateway IEC 61850 Protocol Concentrator for Electrical Substations with DNP3 Modbus and ICCP Conversion

The Kalkitech Mercury Gateway is the protocol concentrator designed for the Peruvian electricity distribution company that needs to integrate into its energy control SCADA the protection and control IEDs of a substation modernized with IEC 61850 Ed.2 — Siemens 7SD protection relays, ABB REF615 reclosers, Arteche electronic measuring transformers — with the existing SCADA server that only speaks DNP3 Level 3, because the cost of replacing the SCADA server and reprogramming all data points exceeds the cost of modernizing ten substations with IEC 61850 IEDs.

The automatic IEC CIM data mapping — Common Information Model from IEC 61970 standard — converts the semantic description of substation data in the IEC 61850 object model (LD, LN, DO, DA with quality and timestamp attributes) into the SCADA's DNP3 point representation, preserving data semantics — it is a circuit breaker state, not an anonymous binary value — in the destination DNP3 point through naming the point with the source attribute's IEC 61850 path, so the SCADA operator can see "IED_REL1/XCBR1.Pos.stVal" as the DNP3 point name instead of anonymous "AI_0042".

HSR network redundancy in the IEC 61850 substation process network guarantees GOOSE and Sampled Values message transfer with zero milliseconds fault recovery time, versus the 200-300 ms of standard RSTP protocol that is inadmissible for transformer differential protection trip GOOSE messages requiring maximum 4 ms latency per IEC 61850-5.
