SEL-451-4 Bay Control, Automation, and Protection System
Major Features and Benefits
The SEL-451-4 Bay Control, Automation, and Protection System integrates bay control for breakers and disconnect switches with full automation and protection in one device. ➤ Commissioning. Rapidly commission your Bay Control with preconfigured bay arrangements. Choose among different bus configurations,including single- and dual-busbar, transfer bus, tie breaker, breaker-and-a-half, ring-bus, doublebus/double-breaker, and source transfer configurations. These bus arrangements allow easy status and control of as many as five disconnect switches and two breakers. Additional user-selectable bay types are available via an SEL-5030 Quickset interface that can be downloaded at www.selinc.com. ➤ Automation.Take advantage of enhanced automation features that include 32 programmable elements for local control, remote control, protection latching, and automation latching. Local metering on the large format front-panel Liquid Crystal Display (LCD) eliminates the need for separate panel meters. Use serial and Ethernet links to efficiently transmit key information, including metering data, protectionelement and control I/O status, IEEE C37.118 Synchrophasors, IEC 61850 GOOSE messages, Sequential Events Recorder (SER) reports, breaker monitor, relay summary event reports, and time synchronization. Use expanded SELOGIC® control equations with math and comparison functions in control applications. High-isolation inputs have settable assertion levels to easily combine

inputsfrom different systems. Incorporate up to 1000 lines of automation logic to speed and improve control actions. Protection. Use multiple instantaneous and timeovercurrent elements with SELOGIC control equations to customize distribution protection. Best Choice Ground Directional Element™ logic optimizes directional element performance and eliminates the need for many directional settings. Protect twobreakers with one relay. Synchrophasors. Make informed load dispatch decisions based on actual real-time phasor measurements from across your power system. Use synchrophasors to determine actual stability margins with standard spreadsheet, graphics program, or data management system. High-impedance Fault Detection. The optional high-impedance fault (HIF) detection element operates for smallcurrent ground faults typically caused by downed conductors on ground surfaces such as earth, concrete or other poorly conductive materials. HIF event data are made available in standard COMTRADE format. Ethernet Access. Access all relay functions with the optional Ethernet Processor. Interconnect with automation systems using IEC 61850 or DNP3 protocol directly. Optionally connect to DNP3 networksthrough an SEL-2032 Communications Processor. Use file transfer protocol (FTP) for high-speed data collection. Connect to substation or corporate LANs to transmit synchrophasors in the IEEE C37.118-2005 format using TCP or UDP internet protocols.

➤Enhanced MIRRORED BITS® communications to monitor internal element conditions between bays within a station, or between stations, using SEL fiber-optic transceivers. Send digital, analog, and virtual terminal data over the same MIRRORED BITS channel. Monitoring. Schedule breaker maintenance when accumulated breaker duty (independently monitored for each pole of two circuit breakers) indicatespossible excess contact wear. Electrical and mechanical operating times are recorded for both the last operation and the average of operations since function reset. Alarm contacts provide notification of substation battery voltage problems (two independent battery monitors) even if voltage is low only during trip or close operations. Breaker Failure.
