Mission-critical communications for utilities

Multi-service technology portfolio for power utilities

Aging infrastructure, new regulations, distributed energy resources and the growing number of information technology (IT) applications within the operational technology (OT) field driven by digitalization are just a few of the issues that are dramatically changing the utility landscape today.

Mission-critical communications systems from Hitachi Energy are ready for the challenges of tomorrow, providing robust, secure and reliable communications that are with you for the life of your network.


Mission-critical communications for power transmission

Unlike telecom-oriented vendors, who may step away from certain technologies, Hitachi Energy continues to support the extension of customers’ operational communication networks for decades. We continue to support critical applications based on traditional technology and provide future-proof technology that support hybrid solutions. 

  • Teleprotection: Hitachi Energy's optimized teleprotection solutions lead to superior performance, higher availability, and reduced operational costs. With the latest generation of protection interfaces and devices, alongside the capability to enable the technology migration of these services. FOX615 provides integrated protection solutions for distance as well as differential protection applications over any kind of network technology (SDH or MPLS-TP). With the latest extension of IEC 61850 based protection interfaces, the FOX615 is the most advanced solution for your teleprotection system and provides you with a migration path to new technologies.
  • Cybersecurity: Hitachi Energy's layered mission-critical communication architectures ensure improved network security. Additionally, Hitachi Energy has developed the first encryption card for mission-critical infrastructure with truly random numbers based on quantum physics. Improving cybersecurity of operational communication network by applying wire-speed encryption suitable for real-time applications. In addition, application-specific firewalling offers controlled access to the station bus for IEC 61850 GOOSE, sample value data, and static network design without an extensive control plane. This ensures the defense-in-depth approach and is supported all in the FOX615 platform.
  • Power line carrier: Hitachi Energy draws on over 75 years of experience of data transmission on power lines. Hitachi Energy's power line carrier communications portfolio offers extensive functionality. It is easy to configure and to upgrade – thereby ensuring that the customer remains at the forefront of technology for years to come.
  • IEC 61850 GOOSE: Recent development of IEC 61850 standard as well as activities in the Teleprotection industry lead towards generic packet-based protection schemes. For line distance protection the IEC 61850 standard allows the use of GOOSE messages. FOX615 with the integrated TEGO1 interface provides an IEC 61850 Gateway functionality where the TEGO1 interface card acts as an IED, connects to up to 8 different remote ends and provides selective filtering of GOOSE messages, translation capabilities in case of miss-matching configurations and controlled access to the station bus from remote ends through the WAN.
  • Network management: All Hitachi Energy Communication Network solutions are fully integrated into FOXMAN-UN , including FOX615 and it’s utility-specific interfaces for distance and differential protection. FOXMAN-UN provides sophisticated supervision features, such as a graphical representation of the communication network, a view of the synchronization status of FOX615 network elements, and performance monitoring of links. In addition, FOXMAN-UN allows certain tasks, such as firmware distribution and activation, to be automated and scheduled.
  • SCADA: Today’s utilities depend on automatic systems to monitor, control, and protect their network and the investment it represents. Modern automation isn’t just about collecting, and collating, data; though that remains a central task of any automation system, the increasing intelligence of IED’s, Relays, and RTUs offers scope for greater autonomy too. Mission-critical communications enable decisions to be made locally, or in concert with other local devices, while centralized SCADA systems alert human operators to decisions made by the machines.

Mission-critical communications for power distribution

Our solutions for distribution automation improve grid reliability and efficiency, and give you control of the grid, anywhere, any time. We help you see inside your grid, with mission-critical communications technology backed by more than a century of experience in substation automation, communication and protection.

  • Distribution Automation (DA): Distribution Automation (DA), also known as Feeder Automation (FA), encompasses a broad range of applications that help utilities make more efficient use of their distribution feeder systems. For example, utilities can confidently operate closer to the physical limits of their systems with the increase in more robust data for planning, engineering, and maintenance, extending equipment useful life.
  • Advanced metering infrastructure (AMI): A communications network is a foundational part of a utility Advanced Metering Infrastructure (AMI) architecture, delivering bidirectional connectivity between smart meters and head-end utility systems.
  • Utility Mobile Workforce Management: Real-time wireless communication enables linemen and other mobile utility workers to bring a virtual office anywhere in their service territory, improving productivity and safety.
  • Outage Management: Minimizes the duration of an outage by automatically detecting and isolating distribution feeder faults and rerouting around them if possible, with little or no manual intervention.
  • Volt/VAr optimization: Used to improve the efficiency of the distribution feeder system through automated control of capacitor banks and voltage regulators.
  • Physical security: Adding network communications to existing substations to extend reach to the various security devices around the yard is often physically or financially prohibitive. As wireless networks require no trenching, they are typically the most cost-effective solution for existing substations. Some of the physical security applications commonly used are video surveillance cameras; access control using biometrics, keypads, etc.; perimeter sensors that detect thermal/motion; and gunshot detection, alerting, and location identification.

Mission-critical communications for substation automation

Substation automation is a key smart grid application. Our mission-critical communications solutions enable remote monitoring and control of intelligent electronic devices (IEDs) through the substation to achieve improved power grid reliability and visibility as well as lowered operational costs.

  • Seamless redundancy: HSR (High Availability Seamless Redundancy) offers redundancy by sending messages through both directions in the same network and detecting broken communication links and alarming the user accordingly. With PRP (Parallel Redundancy Protocol), a message from an IED is sent through two identical independent networks thus removing the risk of communication breakdown in case there is a fault in one of the networks.
  • Security of protected network: Depending on the application requirements, different measures need to be taken, starting from denial of service protection, protection against data modification using authentication, up to encryption of confidential data, and centralized user account management. This ensures a "defense in depth" approach.
  • Switches, routers, and firewalls: The increase of Ethernet-based communication protocols, such as IEC 60870-5-104, paved the way for switches in local area networks of utilities. Critical applications such as IEC 61850 signals or SCADA data can be transmitted via fast and reliable Ethernet networks in the substation environment.
  • Integration of Ethernet/ IP and legacy services: FOX615 addresses the needs of existing legacy networks, while at the same time providing future-proof equipment capable of evolving towards packet-based transport networks. This reduces the operational costs for our customers’ networks and enhances the reliability and the availability of services through reduced network complexity.
  • IEC 61850 enabled platform: The TEGO1 interface module now further extends the capabilities of the FOX615/612 multiplexing platform to enable IEC 61850 GOOSE based line protection. With the ongoing digitalization of electrical substations, the GOOSE based line distance protection application brings significant advantages to our customers and further strengthens our digital substation offering.
