Smart Grid: 4G LTE Router for secondary substations

The integration of distributed energy resources (DER) and electric vehicles into the grid requires reliable and secure automation and connectivity for compact secondary substations. 4G LTE is the easiest solution for large scale rollouts in Smart Grids. 

 

Smart Grid: 4G LTE Router for secondary substations

Welotec industrial TK800 Routers are made for the use in power substations

The rugged industrial design with a special focus on immunity in high EMC environments and enterprise IT features make the TK800 4G LTE Routers the first choice for critical applications in the energy sector.

The Welotec Routers are the right solution for high security and reliable connectivity in secondary substations

The secondary substation router aggregates traffic from various IEDs and RTUs and routes traffic to both primary and secondary regional Control Centers hosted by the DSO via 4G LTE. The router encrypts the application traffic using OpenVPN and IPSec tunnels for maintaining confidentiality of application data over the public network. The headend router in the DSO Control Center aggregates various secured tunnels from multiple substations and decrypts the encrypted traffic; the traffic is routed after decryption to various SCADA application.
