Power Utility Communications

 RAD’s Service Assured Networking solutions provide its worldwide energy utility customers with field-proven communications solutions that address the automation, Teleprotection and core operational network needs of their transmission and distribution (T&D) grids.

Multiservice Operational Networks

  • Powerful cross-generation TDM and Ethernet capabilities, including TDM DS0 cross connect and SDH/SONET, Gigabit Carrier Ethernet with OAM and assured QoS, TDM pseudowire, Ethernet over NG-PDH/SDH/SONET, and OTN/DWDM
  • Complete cyber attack prevention suite, including encryption, authentication, authorization, and auditing
  • Easily configurable connectivity of all serial automation and Teleprotection devices to either SDH/SONET network or to a packet network
  • Supports analog and digital data and voice devices, as well as Ethernet IEDs, with versatile rates from RS-232 up to STM-4/OC-12 or GbE
  • Guaranteed smooth migration to PSNs based on hybrid design for reduced latency and better resiliency
  • Future-ready with virtualization capabilities, for adding new applications (security, router, SCADA) using RAD’s innovative x86 D-NFV module

Distance and Differential Protection Communications

  • Single product supports both distance trip command relays and differential Teleprotection delivery over TDM or IP network
  • Wide range of Teleprotection interfaces — serial, G.703 codirectional, E&M, C37.94 — to extend differential Teleprotection relay communication over any infrastructure
  • Reduce CapEx and OpEx by using a single-box solution for all substation communication services, including voice, data, automation and Teleprotection signals
  • Redundancy hierarchy from the Teleprotection interface up to the communication link ensures 0 (zero) msec hardware protection
  • Sub-2 msec end-to-end delay over PSN
  • Tested interoperability with most Teleprotection contact relays from leading vendors (such as Alstom, ABB, Siemens, SEL, Schneider)
  • Distance protection complies with IEC 60834

Ruggedized Substation LAN

  • Support Ethernet-based IEC 61850 substation communications for mission-critical automation traffic within the substation and between SCADA control centers
  • Enable co-existence of serialbased RTUs and Ethernet IEDs with full redundancy over various topologies using fiber optic rings, 3G/4G cellular modems and external radio systems
  • Comply with IEC 61850-3 and IEEE 1613 environmental standards
  • Built-in router enables seamless communication of IP SCADA SecFlow-2 Ruggedized SCADAAware Ethernet Switch/ Router Megaplex-4 Next-Generation Multiservice Networking Node to both old and new RTUs by converting IEC-101 and IEC-104, or Modbus serial and IP, DNP3 and others
  • Enable secure, dedicated networks over fiber and/or radio links using IPsec encryption and distributed security SCADA firewall suite


Distributed Automation and Smart Meter Backhaul

  • A comprehensive solution addressing communications to secondary substations, metering and automation network integration, and cyber security
  • Comply with IEC 61850-3 and IEEE 1613 environmental standards for outdoor installations
  • Seamless communications over fiber optics, radio links, 2G/3G/LTE cellular links and leased lines from a telecom service provider
  • Integrated IPsec with SCADAaware firewall and encryption
  • Point-to-multipoint radio connectivity supports high capacity mission-critical traffic over licensed and unlicensed sub-6 GHz bands, with dedicated bandwidth allocation and service level agreement (SLA) per subscriber
  • Transparent delivery of SCADA protocols
