SIC-A Redundancy Protocols Gateway (PRP/HSR)

A traditional point of view about the energy sector was focused on a generation, transmission and distribution in a lineal way, where the communication was concentrated on the substation. The substations devices shared the information with the control center “in-situ” using serial protocols. With these protocols, the information was limited and it was insecure.

With the “Smart Grid” concept evolution, the energy generation is not restricted by specific generation centers. A huge radial infrastructure requires an advanced communication infrastructure. This concept includes not only the latest Ethernet protocols; also the redundant protocols become indispensable.
This technology implies an important technology leap for the industry, due to the transmission of a huge amount of data, in many cases in real time, is required.

To implement these new technologies the industry requires an easy and flexible system that is able to adapt to its all requirements.
The protocols gateways provide an easy way to adapt the existing devices to the new technologies.

Redundancy Protocols Gateway (PRP/HSR)

  • Communication Solutions for Smart Grid
  • Supported protocols: IEC 61850, IEC 60870-5-101/103/104, DNP3 serial/TCP, Modbus RTU/ASCII/TCP, IEC 62056 – DLMS, IEC 61400, …
  • Multifunction:

Redbox

SIC-A Working as a Redbox allows the connection of HSR networks with traditional ones. In case of PRP redundancy, SIC-A is not denominated Redbox, it would be a device that allows the integration into 2 independent networks through a 3rd Ethernet port.

Protocol Gateway

SIC-A device is able of communicating through serial communication RS-232 or RS-485 with multiple equipment with a Master serial protocol (Modbus, IEC69870-5-101, IEC60870-5-103, DLMS…) and dispose the information into a Ethernet protocol as IEC 61850 or IEC 60870-5-104. This way, devices with conventional protocols can be integrated in Ethernet networks with advanced protocols.

Redundant Protocol Gateway

It is the result of the combination of the functionality of a Gateway and the HSR redundancy. With this configuration, SIC-A allows the integration of equipment with serial communications in a HSR redundant network with an advanced protocol as IEC 61850 or IEC 60870-5-104

Most complete topology

2 SIC-A in their topology of Redbox allow connecting a HSR redundant network with another PRP network. This is a useful application that permits to coexist new networks with existing ones. In the same way, SIC-A in its topology of PRP Gateway, would allow to integrate serial equipment with conventional protocols in a PRP network with an advanced Ethernet protocol as IEC61850, IEC 60870-5-104, etc.

How the HSR redundancy works with a GOOSE application according IEC 61850. In the following demonstration it is shown a feeder protection SIL-B with IEC 61850 protocol that sends a GOOSE message simulating a trip.
