Cost Effective Industrial Wireless Communication for Smart Grids
Blog Category: Industrial Ethernet

Posted by: Germán Fernández on February 17, 2016

People in many countries take reliable electricity service for granted. That’s because over the years large, mature, highly connected electric grids have been built out.

These electric grid systems used to operate perfectly well with one-way communication from the central stations out to the ultimate users. In the last two decades though, the addition of renewable and stored sources of power made bidirectional communications a necessity.

Furthermore the drive for efficiency and resiliency has led to a demand for smart grid applications such as grid visualization, real-time load monitoring, asset monitoring, smart metering and consumer load control.

Providing two-way communications over a vast grid is a daunting challenge. Fortunately there is a straightforward and cost effective solution. Public cellular networks along with the right network design and routing equipment can be combined to deliver reliable, high data rate solutions.

Let’s examine how to develop industrial wireless networks for today’s smart grid applications.

Industrial Ethernet Switches Update Substations to IEC 61850
Blog Category: Industrial Ethernet

Posted by: Germán Fernández on May 25, 2016

Electric energy operators around the world are working to increase reliability, resiliency and capacity with smart investments in new technologies. This includes Stadtwerke Karlsruhe Netzservice GmbH (SWKN), the municipal utility that provides electricity, gas, water and heating to the 300,000 inhabitants of the city of Karlsruhe in southwestern Germany.

In conjunction with replacing primary electric transmission equipment with new gas insulated switchgear (GIS), SWKN wanted to improve the reliability of its substations. Doing so included upgrading the control and automation system from legacy protocols to the IEC 61850 communication standard.

There is a lot than can be learned from this real-life example of how a utility updated its systems for real-time monitoring and control, aligning with the vision of the Smart Grid. Let’s take a look at how they did it.
