An Industrial Revolution for Protection & Control

The HardFiber Process Bus System represents a true breakthrough in the installation and ownership of protection and control systems, by reducing the overall labor required for substation design, construction, and testing. This innovative solution addresses the three key issues driving the labor required for protection and control design, construction and testing:

  • Every substation is unique making design and drafting a one-off solution for every station
  • Miles of copper wires needs to be pulled, spliced and terminated
  • Time consuming testing and troubleshooting of thousands of connections must be performed by skilled personnel

The HardFiber System was designed to address these challenges and reduce the overall labor associated with the tasks of designing, documenting, installing and testing protection and control systems. By specifically targeting copper wiring and all of the labor it requires, the HardFiber System allows for greater utilization and optimization of resources with the ultimate goal of reducing the Total Life Cost (TLC) for protection & control.

Key Benefits of the HardFiber System

The underlying driver for the HardFiber System is the reduction of Total Life Costs of protection and control through labor and resource optimization. This optimization is achieved by replacing individual, labor-intensive, individually terminated copper wires with standardized physical interfaces and open digital communications.

Traditional substation designs require large amounts of skilled labor to create engineering drawings, pull and terminate miles of copper cables, and test and troubleshoot thousands of connections.

Ruggedized Brick

Process Interface Unit

The HardFiber Brick Process Interface Unit (Order Code BRICK-4-HI-R-****-R-X-X) is ruggedized I/O device designed for mounting outdoors in utility switchyards with 8 analog measurements, either 4 currents / 4 voltages, or 8 currents, along with 18 contact inputs, 3 universal DC inputs, 4 Form-A tripping contacts, 2 Form-C signaling contacts, and latching contact. The Brick uses connectorized copper and fiber optic cables for ease of installation and for environmental protection. The R-Brick works directly with models of the GE Universal Relay (UR) family. Manufacturing for the Brick with the Ruggedized Switchyard Hardened Interface has been discontinued. As an alternative, please refer to MU320E.

Fiber cable options for the Brick

Manufacturing for the Brick Cables have been discontinued.

Custom FOA cable

The custom FOA cables are ordered to length and are connectorized at each end. These FOA cables require the use of the Cross Connect Panel, and the FOR Indoor Relay Fiber Cable, to connect to the UR relay. DC power to the Brick is distributed by the Cross Connect Panel, and short circuit protection for the Brick power supply is included in the FOA cable.

FOA Splice cable

The FOA Splice Cable is intended to meet customer standards for fiber optic cable distribution through the switchyard. The FOA Splice Cable is connectorized at the Brick end and ends in copper and fiber pigtails. The customer must provide their own fiber optic cables across the switchyard, DC supply to power the Brick, DC short circuit protection for the Brick power supply, and perform their own splicing to the pigtails of the FOA Splice Cable

  Using the FOA splice cable

S-Brick Process Interface Unit

The HardFiber S-Brick Process Interface Unit (Order Code: BRICK-4-HI-S- ****-*-X-X) is intended for mounting inside marshalling cabinets, kiosks, and equipment control cabinets. The S-Bricks have 8 analog measurements, either 4 currents / 4 voltages, or 8 currents, along with 18 contact inputs, 3 universal DC inputs, 4 Form-A tripping contacts, 2 Form-C signaling contacts, and latching contact. It uses standard terminal blocks for connecting copper cables to interface with primary equipment. Fiber optic cables require the use of one simplex LC connector for each of the four fiber optic cores. The HardFiber S-Brick Process Interface Unit works directly with models of the GE Universal Relay (UR) family. The S-Brick requires the customer to provide copper cabling to interface with primary equipment, DC supply to power the S-Brick, and fiber optic cabling and cabling management between the S-Brick and end device

  Fiber optic cabling

Fiber optic cabling

The Multilin HardFiber System requires the use of 50/125 mm multimode fiber, that support 1310nm and 1550nm transmission. Class 1 graded index fiber is ideal. In general, OM2 and OM3 rated fibers meet these requirements. Environmental rating of the fiber cables is as per customer application. The S-Brick and the UR have female LC connectors, so cables must use male LC connectors at these ends. The S-Brick has 4 LC connectors, while the UR has 8 LC connectors. Commercially available fiber optic patch panels may be used for cable management. The customer must provide a 125 or 250 VDC rated supply to power the S-Brick. The DC circuit must provide short circuit protection for the S-Brick power supply, (1A, fast acting, 10,000 A DC interrupting capacity, Littelfuse KLKD001 or equivalent). The general recommendation is to power the S-Brick separately from the associated primary equipment for good operating and maintenance practices.

System Architecture

The architecture of the HardFiber System is driven by the mapping of signals between the primary apparatus and the protection and control devices.
The measurement of field signals and respective mapping of these signals, using the open IEC 61850 communications protocol, back to the control house is done through a hardened interface device called the HardFiber Brick.

Using made-to-order Outdoor Fiber Cables connecting the Brick to a Cross Connect Panel in the control house provides fast and error-proof installation without the need for on-site splicing or terminating.

Keeping true to the existing topology of traditional substations, each protection and control device included in the zone of protection will be connected directly to Bricks through dedicated fiber optic connections.

This simple, purpose-driven architecture that uses the IEC 61850 open standard for communications, provides dedicated point-to-point connections between the Brick and protective relays without introducing any issues relating to data synchronization, setting management or Cyber Security.

Zone protection

Each Brick transmits measurements and accepts controls from up to 4 separate protection and control devices.

  The hardfiber system can easily be incrementally scaled to include new equipment as stations evolve. Duplicated bricks in the switchyard provide a drastic improvement in reliability and security over today's technology.

Scalability

The true test of any system, including a Process Bus system, is its ability to incrementally scale up to meet specific applications without adversely affecting the other devices in the system. Today’s protection and control systems are already naturally scalable.

The challenge for communication-based protection systems becomes making extensions and modifications without disrupting the in-service protection and control system.

By recognizing that the mapping between power system signals and protection and control devices is fundamentally driven by the topology of the underlying substation, the HardFiber System is optimally partitioned and connected to allow for additions, modifications and upgrades to the system – without risking interruption or degradation to critical in-service protection.

Reliability, Dependability, Security

The HardFiber System provides an unprecedented level of diagnostics and self-checking, allowing critical protection and control systems to do something that they have never done before – operate without routine maintenance.

Internal diagnostics and self-tests within each Brick monitor dozens of critical internal subsystems and provide this information several hundred times per second. Duplicate Bricks can be provisioned to acquire each input signal twice, allowing protection and control devices to continuously crosscheck critical protection measurements before executing commands via fully redundant outputs.

With the HardFiber redundant architecture, each protection and control device can be configured to maximize dependability and security, addressing specific application requirements.
