Actual feeder/collector configurations may vary. 4 SEL Solutions for Wind Energy Wind Generator Feeder Protection The SEL-700GW provides complete dual feeder protection for distributed generation. High system availability is obtained by using two sets of overcurrent elements (50/51) to detect and isolate a fault on either feeder. The SEL-700GW also provides many functions of a programmable logic controller (PLC). Multiple communications options, a variety of I/O choices, and programmable SELogic® control equations make the SEL-700GW a complete solution. SEL-700GW Wind Generator Protection Relay Grid Interconnection The SEL-700GT provides an IEEE 1547-compliant intertie protection solution for distributed generation. Optional synchronous generator protection and synchronization provide complete generator and intertie protection in one compact and economical package. Multiple communications options, various I/O choices, and programmable SELogic control equations make the SEL-700GT a complete solution for intertie and generator protection. SEL-700GT 52Y SEL-700GT Intertie Protection Relay Fault Indication SEL Faulted Circuit Indicators (FCIs) help operations personnel quickly determine the fault location, isolate the faulted section, and restore power. As depicted in the illustration below, the terminations used for underground cables in the transformers and junction boxes are excellent locations to install faulted circuit indicators. Features and benefits include: • Line-powered operation (no batteries required) means longer life and limited maintenance. • High 1200 A current trip value with delayed trip response time option coordinates with most systems. • Remote display allows indicator status to be quickly determined without opening the enclosures. • Easy installation on terminators with capacitive test points saves time. • Integrated junction shields ensure adjacent phase immunity in junction box applications. • Applicability in both transformers and junction boxes reduces installation errors. SEL Test Point Rest Faulted Circuit Indicator 5 SEL Solutions for Wind Energy Distributed Generation Interconnection The SEL-547 Distributed Generator Interconnection Relay allows a wind turbine to be connected to the electric utility grid. When the SEL-547 detects a condition that could adversely affect the generator or the electric grid, it sends a trip signal to the breaker, separating the wind turbine from the utility supply. SEL-547 Distributed Generator Interconnection Relay • Low-cost compact package incorporating essential protection and control elements for distributed generation • Protection and control elements required by IEEE 1547 • Modbus® and SEL communications interface Revenue and Power Quality Metering The SEL flagship SEL-734 and SEL-734P Advanced Metering Systems provide high-accuracy, fourquadrant metering with advanced load profile recording. In addition to revenue metering, the SEL-734P meter provides advanced yet user-friendly power quality reports, capacitor bank control, and time-synchronized phasor measurements. Indoor mounting options and prewired outdoor enclosures from SEL facilitate high-end metering at virtually any location. SEL-734 Advanced Metering System Feeder Protection SEL-751A Feeder Protection Relay With Arc-Flash Detection SEL feeder protection solutions provide complete feeder protection, with overcurrent, overvoltage, undervoltage, and frequency elements with flexible I/O options, easy mounting, and fast settings. With the SEL-751A Feeder Protection Relay, you can easily upgrade protection without cutting or drilling existing cutouts with a small form factor and multiple mounting adapters. Quickly integrate into serial- or Ethernet-based communications with IEC 61850, Mirrored Bits®, DeviceNet™, and other protocols. The SEL-751A also provides fully automatic protection against dangerous arc-flash events. Without arc-flash detection (AFD), an arc flash can cause severe personal injury, extensive equipment damage, and lengthy system outages. AFD interrupts power to the arc flash before it can cause significant damage. Transformer Protection SEL-787 Transformer Protection Relay SEL transformer protection solutions allow you to optimize the life of your transformers by monitoring key health indicators with cumulative through-fault current recording measurement and logic input. With the SEL-787 Transformer Protection Relay, you can apply 2 three-phase winding inputs, and an optional single-phase restricted earth fault input and three-phase voltage input. Benefits include advanced automation and flexibility, single or dual, copper or fiber Ethernet communications ports, asset management data, and easy retrofit of most electromechanical relays. Alarm and Annunciation Make complex alarming simple with SEL’s alarm and annunciation panels, including 42 inputs, 11 outputs, programmable logic, and up to four communications ports supporting DNP3, Modbus, and SEL protocols. You can simplify commissioning and troubleshooting with a built-in sequence of events recorder and full software HMI. Apply an SEL-3010 Event Messenger for telephone voice callout of critical alarm conditions. SEL-2523 Annunciator Panel SEL-3010 Event Messenger 6 Breaker Failure Protection and Control SEL solutions provide breaker failure protection, breaker control, and breaker monitoring. Benefits of the SEL-352 Breaker Failure Relay include a cost-saving data recorder and a sophisticated controller to reduce maintenance and manual operations. The relay features circuit breaker failure protection, including failure to trip for fault or load conditions; failure to close, including pole disagreement; failure while open (flashover detection); failure to complete a trip or close due to stuck resistor switches; and loss of dielectric pressure. SEL-352 Breaker Failure Relay Line Protection With SEL, you can protect any transmission line using a combination of five zones of phase- and ground-distance and directional overcurrent elements. A graphical user interface system provides logic and application templates for typical line protection schemes while patented coupling capacitance voltage transformer (CVT) transient overreach logic enhances the security of Zone 1 distance elements. Best Choice Ground Directional Element® logic optimizes directional element performance and eliminates many directional settings. Apply the SEL-421 Protection, Automation, and Control System for high-speed distance and directional protection and complete control of a two-breaker bay. Use synchronized phasor measurements (synchrophasors) from SEL relays and meters to detect and correct islanding, interarea oscillations, and other dynamic system conditions. SEL-421 Protection, Automation, and Control System Capacitor Control Simplify relay settings, application, and inventory by using one relay for all of your capacitor bank needs. The versatile SEL-487V Capacitor Protection and Control System can handle grounded and ungrounded, single and double-wye capacitor bank applications. It provides sensitive voltage differential and current unbalance protection with compensation adjustment for small voltage differential levels due to variations in individual capacitor elements from manufacturing, potential transformer, or instrument transformer measurement error. Each differential and unbalance element provides three levels of detection, low set alarm level, trip pickup level, and high-level trip pickup level, each with its own definite time delay. Instantaneous- and time-overcurrent elements, as well as voltage elements, provide backup protection. Information Processors SEL information processors integrate power protection, automation, control, and monitoring by communicating with a variety of microprocessor-based devices. With the SEL-3530 RealTime Automation Controller (RTAC), you can integrate station control, reporting, and logging through one reliable system. acSELerator RTAC™ Software simplifies the design of integration and automation while the embedded RTAC web interface speeds setup and monitoring of critical data on network access, user accounts, and system performance. SEL-487V Capacitor Protection and Control System SEL-3530 Real-Time Automation Controller (RTAC) Satellite-Synchronized Timing SEL provides a reliable, accurate, low-price time source for synchrophasor, relay event correlation, and other high-accuracy timing needs.
