BE1-11i — intertie protection system for distributed generation connection points
BE1-11i is an intertie protection system on the BE1-11 platform for connection points where consumers with their own generation connect to the network. It combines protection, monitoring and control, with communication over 10/100 Mbit/s Ethernet using IEC 61850, DNP and Modbus®. It is used with cogeneration, solar and wind plants and energy storage.

Description
BE1-11i is an intertie protection system for connection points where consumers with their own generation connect to a utility network. It provides extended protection, monitoring and control of such connections. Setup and commissioning are simplified by BESTspace™ files, ready-made BESTlogic™Plus schemes and application materials. The device is installed on connections to utility networks, distributed generation systems and industrial power systems where protection and control of the connection point are required.
The task of intertie protection is to quickly separate the facility's own generation from the network during faults and abnormal conditions, such as voltage and frequency deviations, reverse power flow and loss of connection with the network. This prevents out-of-synchronism reclosing and operation on an isolated section of the network. Protection, monitoring and control are combined in one device, so the connection point does not need separate relays for each function.
All BE1-11 versions share one firmware and common platform features: 24 standard time-current characteristics and a practically unlimited number of user-defined curves; Ethernet 10/100 Mbit/s over copper or 100 Mbit/s over fibre with IEC 61850, DNP and Modbus® protocols; large screw terminals. The relay provides fault distance location, oscillography, energy consumption records, power quality indicators and breaker monitoring. The front panel has an HMI menu with a large LCD, programmable indicators and labels, and select–execute buttons. Analog outputs are configurable.
Configuration is simplified by BESTspace™ files, ready-made BESTlogic™Plus schemes and application guides, and the offline simulator checks the logic without hardware. Oscillography records event data for later analysis, and fault distance location shortens the search. Energy consumption records and power quality indicators show the operating mode at the connection point. Applications include industrial cogeneration plants, solar and wind power plants, energy storage systems, microgrids and standby generator sets operating in parallel with the network. The manufacturer designs and builds excitation regulators, protection systems and controllers at its plants in Illinois and Texas, USA.

Questions and answers
Which facilities is the BE1-11i intended for?
For connection points of consumers with their own generation to a utility network, distributed generation systems and industrial power systems. It is used in cogeneration plants, solar and wind power plants, energy storage systems and microgrids.
Which protocols and interfaces does the BE1-11i support?
Ethernet 10/100 Mbit/s over copper or 100 Mbit/s over fibre, with IEC 61850, DNP and Modbus®. The BE1-11 platform also provides oscillography and fault distance location.
Which conditions does intertie protection guard against?
It quickly separates the facility's own generation from the network during voltage and frequency deviations, reverse power flow and loss of connection with the network. This prevents out-of-synchronism reclosing.
