Substation Interface Module Expands Application Range of IntelliTEAM Automatic Restoration System.

The IntelliTEAM® Remote Substation Interface Module enables substation relays and breakers to operate as part of the IntelliTEAM® Automatic Restoration System, helping to further minimize the impact of outages. Interfaced with the substation microprocessor relay, the module provides full team-member logic and communication capabilities. The module allows IntelliTEAM logic, after the loss of substation bus voltage, to restore power to the line segment between the substation breaker and the first switch. The Substation Interface Module can also allow an additional reclose attempt, if desired, and still restore all unfaulted line sections.

The IntelliTEAM Substation Interface Module adds IntelliTEAM functionality to the fault-interrupting decisions made by the relay. The module exchanges information with the other team members as needed and polls the relay for status and analog data, which are used for the IntelliTEAM process. If a fault interruption or loss of source occurs, the module provides the interface to, and operates, the substation relay/breaker to restore as many feeder segments as possible.

The module is rack-mounted, 19" wide and 3 spaces high. It communicates with the relay through a DB-9 connector on the back. Data (including alarm and team status) is shown on a 2-line display. The tactile-feedback membrane switches allow easy scrolling through the IntelliTEAM information.

Programming, setpoints, and logged data are stored in permanent, non-volatile memory. The crystal-controlled clock accurately time stamps data. The IntelliTEAM Substation Interface Module has three communications ports: one for team communications, one to communicate with the relay, and a DB-9 faceplate connector for local monitoring and configuration. The local data port allows you to connect your computer to the module and change setpoints or upload logged data using the user-friendly IntelliLINK® Setup Software. The control software in the module can also be updated, offering a simple migration path to new features.

The module uses DNP protocol for peer-to-peer communications with IntelliTEAM system team members and for communication between the module and a SCADA master station.
