BPL communication system

For over 30 years, we have been observing the dynamic development of the TCP/IP backbone network in LV and HV transmission and distribution networks using fiber optic lines. Currently, virtually every HV substation with a MV switchboard (so-called GPZ) has an interface to the TCP/IP backbone. It seems that a natural continuation of the expansion of the TCP/IP backbone for LV and HV power networks would be to extend the backbone to the MV and LV networks. This can be achieved using BPL technology (Broadband Powerline Communication – broadband, fast TCP/IP communication in medium and low voltage networks).

The ability to use BPL's broadband communication technology, 100% compliant with the TCP/IP standard, allows for the flexible and seamless connection of various TCP/IP-compliant communication systems within the power grid. BPL offers an ideal solution for the implementation of Smart Metering systems and Smart Grids. The standard makes connecting different communication systems within a single power grid flexible and trouble-free.   []

Main features of the BPL system

• Fast and stable
  The maximum data transfer rate of 200 Mbps on low-voltage (230/400V) and medium-voltage (1 to 36kV) power grid lines allows for significantly higher data throughput (approximately 1000 times faster) compared to narrowband transmission systems – bidirectional and in real time. Simultaneous transmission from multiple measurement points is possible simultaneously.
• Open and scalable
  TCP/IP-based communication, along with the ability to use open interfaces, regardless of the manufacturer of the measurement or communication devices.
• Flexible integration
  The numerous interfaces that BPL devices are equipped with, such as an interface to a narrowband PLC, as well as radio interfaces such as wireless M-Bus, RF, or Zigbee, enable the quick configuration of extensive Smart Grid networks.
• Efficient
  Using the existing electrical network saves on investments in additional telecommunications infrastructure. Easily expandable
  High data transmission speeds enable the further implementation of additional applications, such as substation monitoring, SCADA systems, power grid load management, and electromobility (operating electric vehicles).   []

Advantages of the BPL technology offered:

• General availability - use of existing power grids
• Based on the global standard - Internet Protocol (TCP/IP)
• Ensuring bidirectional, broadband data transfer
• Real-time communication
• Prospective - use of open standards and open interfaces
• Not limited to specific applications; many different applications can use this technology simultaneously
• Enables quick and easy deployment of large networks - Plug & Play installation
• Applicable in meshed networks
• Optimal connection quality - Dynamic routing between individual nodes (even during operational switching processes in the distribution network, with auto-configuration capability)
• Adapted to the operational standards of energy distributors (does not affect operational network operations)
• Continuous control and central configuration of all BPL system components - NMS network management system with SNMP protocol
• Integrated firewall

Examples of devices that make up a communication system for BPL transmission:

• BPL Gateway/Client End Device
• BPL Head End (HE) - manager of the low-voltage BPL network
• Medium-voltage Modem
• Medium-voltage Coupler   []
