net-line BCU-50

Sturdy and stable substation automation

Bay station controllers in the electrical power supply must withstand special environmental requirements, especially when the station automation is used in high-voltage equipment, strongly vibrating or shock generating system components or also in environments with a seismic risk. We have therefore developed an extremely sturdy bay station controller with the net-line BCU-50, which fulfils the requirements of modern substation automation. Like all products from SAE IT-systems, the BCU-50 is also distinguished by high functionality and durability as well as tremendous performance.

Voltage and shock-resistant

The net-line BCU-50 has been developed in line with the product standard DIN EN 61850-3. According to this standard, it is suitable for use in locations such as power stations and medium voltage stations "G", high-voltage switchgears "H" as well as for signal and field connections "f" and high-voltage connections "h". Thee dielectric strength of the bay station controller corresponds to Class VW3 as per IEC 60870-2-1. Also in respect to shock resistance (DIN EN 60068-2-6), vibration strength (IEC 60068-2-27) and seismic vibrations (EN 60255-21-3), the net-line BCU-50 fulfils the high requirements of the standards. Consequently the system can also be used in regions prone to earthquakes. The system cards designed for tough use in the rough environment of switching housings, transformer stations and high voltage systems enables safe operation.

Application fields of the net-line BCU-50

A series of powerful functional modules forms the basis of the numerous possibilities for using the BCU-50. These include for example convenient cross-connection (of information between different telecontrol stations), as well as the integration of external components (for instance protective device coupling via IEC 61850 or IEC 60870-5-103). The main application fields of the BCU-50 are:

  • Station and bay controller in medium and high-voltage switchgears
  • Gateway and communication router between station buses, field bus and control systems
  • Monitoring and control unit for the utilities, waste management and manufacturing industry

Same as at its brother FW-50, a particular strength of BCU-50 lies in the implementation of communication tasks with substations and control systems of many different manufacturers.

High IT security with the net-line BCU-50

Like all products of the series5e, the BCU-50 stands for high IT security. It enables extensive IT security measures, as required in the current requirement profiles of the BDEW whitepaper and BSI recommendations. From the modern Linux kernel to extended firewall rules with granular activation through to user administration with free role assignment (RBAC): The BCU-50 allows an outstandingly high level of IT security.


Ready-to-use complete solutions

If required, the BCU-50 can also be purchased as a ready-to-use complete solution. In this case we design and realise on the basis of exact specifications bespoke, properly wired switchgear cabinets corresponding precisely to the agreed requirement profiles. If required, we deliver directly to the installation site.

You can find more information on the technical specifications of the BCU-50 in the data sheet of the model.
