New Applications Automatic Network Reconfiguration Automatic network reconfiguration augments system reliability by automatically isolating faulted line sections and restoring service to the unaffected areas of the sys- tem. In the simple automatic network reconfiguration implementation in Figure 1 , there is no direct communi- cation between the recloser control sites and there is min- imal voltage sensing. For the sample fault in Figure 1 , system isolation and restoration is methodically accom- plished with: ➤Sectionalism recloser tripping on sensed dead feeder (for line section isolation). ➤Midpoint recloser control changing settings (for better backfeed coordination). ➤Tie recloser closing into dead line sections (for res- toration of unfaulted line sections from adjacent feeder). The advanced automatic network reconfiguration in Figure 2 includes both source-side and load-side volt- ages into the SEL-651R Recloser Controls and MIR- RORED BITS communications (via fiber-optics or radio) between the recloser sites. These enhancements greatly speed up automatic network reconfiguration operation. Apply automatic network reconfiguration especially to urban areas, and critical loads where there are tie points available to other feeders for system restoration.

In Figure 3 , a permanent fault occurs on the middle phase. Single-phase trip- ping/reclosing is enabled and only the middle pole of the recloser opens for the fault. Single-phase reclosing is unsuccessful because of the permanent fault and only the customers on the middle phase are left without power, rather than all three-phases locking out. Available trip-reclose-lockout operation modes for the single-phase reclosers are: ➤Three-phase trip/reclose, three-phase lockout ➤Single-phase trip/reclose, three-phase lockout ➤Single-phase trip/reclose, single-phase lockout ➤Single-phase trip/reclose, single-phase lockout (three-phase lockout if two or more phases involved) Three-phase tripping is still available for the preceding single-phase trip modes. Apply single-phase operation especially to rural areas, where many loads are single- phase and restoration can take longer because of travel distance. Switch between single-phase and three-phase operation depending on time of year (e.g., three-phase operation during pumping season because of three-phase motor loads).

Select the three-phase voltage channel (VY or VZ) to operate features such as fault locating, load encroach- ment, power elements and voltage sag/swell/interrupt recording (features shown listed under the VY voltage channels in Figure 5 example). The voltage channel fre- quency source for frequency elements can also be selected (again, feature shown listed under the VY volt- age channels in Figure 5 example). The VY and VZ voltage channels can optionally be ordered as Low Energy Analog (LEA) voltage inputs. Connect the low-level voltage outputs from less-costly power system voltage transducers (8 Vac output or less) to three-phase LEA voltage inputs on the SEL-651R. Control Power Input Order the control power input (shown as the Vac Power connection in Figure 5) as either 120 Vac, 230 Vac, or 125 Vdc. Various accessories (e.g., fuse blocks, ac trans- fer switch, low-voltage close power) are available with the 120 Vac option. A Ground Fault Circuit Interrupter (GFCI) convenience outlet comes on front of the power module, when the 120 Vac option is ordered (see front cover photo). Use ac transfer switches (see Figure 6) especially in automatic network reconfigurations (see Figure 1 and Figure 2 ). The transfer switch switches to the alternate control power source when the primary control power source is unavailable/dead. The transfer switch mounts on the rear panel of the power module (see Figure 15 ). The incoming control power to the power module is con- verted to: ➤12 Vdc to run the relay module ➤Stored energy in capacitors in the power module to provide trip/close energy for the trip/close outputs of the relay module If the incoming control power is unavailable/dead, then the 12 V battery provides energy for the capacitors in the power module and to run the relay module. The 125 Vdc power input option does not include the 12 V auxiliary supply, battery charger, batteries, or GFCI convenience outlet. Control Cable The control cable, brings secondary current, recloser sta- tus, and yellow operating handle status to the SEL-651R Recloser Control and takes trip/close signals out to the recloser (see Figure 6 ). Control cable connection to the SEL-651R is made to a control cable receptacle/interface at the bottom of the enclosure. NOTE: A single control cable interface is selected at ordering time.

For a nominal recloser CT ratio of 1000:1, these curves can be set as sensitive as 100 A pri- mary for phase and 5 A primary for ground overcurrent protection. Figure 7 Coordinate the SEL-651R With Other Devices Any fast or delay curve can be set with any of the curves in Table 1 . The U.S. and IEC curves conform to IEEE C37.112-1996 IEEE Standard Inverse-Time Characteris- tic Equations for Overcurrent Relays. The traditional recloser curve choices in Table 1 are listed using the older electronic control designations.

For example, a given traditional recloser curve has the following two designations: ➤Older electronic control designation: A ➤Newer microprocessor-based control designation: 101 Traditional recloser curve A and 101 are the same curve. Use either designation in making curve settings in the SEL-651R. Fast and delay curves (including U.S. or IEC curve choices) can be modified with the following traditional recloser control curve modifiers: ➤Constant time adder—adds time to curve ➤Vertical multiplier (time dial)—shifts whole curve up or down in time ➤Minimum response time—holds off curve tripping for minimum time Instantaneous overcurrent trip, definite-time overcurrent trip, and high-current lockout variations are also avail- able. The SEL-651R has two reset characteristic choices for each time-overcurrent element. One choice resets the ele- ments if current drops below pickup for at least one cycle. The other choice emulates electromechanical induction disc elements, where the reset time depends on the time dial setting, the percentage of disc travel, and the amount of current. Load Encroachment Load-encroachment logic (Figure 8 ) prevents operation of phase overcurrent elements under high load condi- tions. This unique SEL feature permits load to enter a predefined area (shown in the impedance plane in Figure 8 ) without causing a trip, even though load cur- rent is above phase minimum trip. Figure 8 Load-Encroachment Logic Defines Load Zones (No Trip Zones) Directional Elements Increase Sensitivity and Security Phase and ground directional elements are standard. An automatic setting mode sets all directional threshold set- tings based on replica line impedance settings. Phase directional elements provide directional control to the phase- and negative-sequence overcurrent elements. Ground directional elements provide directional control to the ground overcurrent elements. Phase directional characteristics include positive- sequence and negative-sequence directional elements that work together. The positive-sequence directional element memory provides a reliable output for close-in, forward- or reverse-bolted three-phase faults where each phase voltage is zero. The negative-sequence directional element uses the same patented principle proven in our SEL-321 Relay. Apply this directional element in virtu- ally any application regardless of the amount of negative- sequence voltage available at the recloser control loca- tion. The following directional elements work together to pro- vide ground directionality: ➤Negative-sequence voltage-polarized element. ➤Zero-sequence voltage-polarized element. Our patented Best Choice Ground Directional Element logic selects the best ground directional element for the system conditions. This scheme eliminates directional element settings. (You may override this automatic set- ting feature for special applications.) Loss-of-Potential Logic Supervises Directional Elements Voltage-polarized directional elements rely on valid input voltages to make correct decisions. The SEL-651R includes loss-of-potential logic that detects one, two, or three blown potential fuses and disables the directional elements. For example, in a loss-of-potential condition, you can enable forward-set overcurrent elements to oper- ate nondirectionally. This patented loss-of-potential logic is unique, as it only requires a nominal setting and is uni- versally applicable. Reclosing The SEL-651R can reclose up to four (4) times. This allows for up to five operations of any combination of fast and delay curve overcurrent elements. The SEL-651R verifies that adequate close power is available before issuing an auto-reclose. The reset times are sepa- rately set for reset timing for an auto-reclose and reset timing for a manual/remote close from lockout. Tradi- tionally, the reset time for a manual/remote close from lockout is set less than the reset time for an auto-reclose. Front-panel LEDs track the control state for autoreclos- ing: 79 RESET, 79 CYCLE, or 79 LOCKOUT (see Positive- Sequence Line Angle Load-Out Region Load-In Region R X Schweitzer Engineering Laboratories, Inc.SEL-651R Data Sheet 9 Figure 11 and Table 4). Sequence coordination logic is enabled to prevent the SEL-651R from tripping on its fast curves for faults beyond a downstream recloser. Cus- tomize reclosing logic using SELOGIC® control equa- tions. Use programmable timers, counters, latches, logic functions, and analog compare functions to optimize control actions. Power Elements Four independent directional three-phase power elements are available in the SEL-651R. Each enabled power ele- ment can be set to detect real power or reactive power. With SELOGIC control equations, the power elements provide a wide variety of protection and control applica- tions. Typical applications are: ➤Overpower and/or underpower protection and control. ➤Reverse power protection and control. ➤VAR control for capacitor banks. Fault Locating The SEL-651R provides an accurate estimate of fault location even during periods of substantial load flow. The fault locator uses fault type, replica line impedance set- tings, and fault conditions to develop an estimate of fault location without communications channels, special instrument transformers, or prefault information. This feature contributes to efficient dispatch of line crews and fast restoration of service. The fault locator requires three-phase voltage inputs. Automation and Communication Flexible Control Logic and Integration Features Use the SEL-651R control logic to: ➤Replace traditional panel control switches ➤Eliminate RTU-to-relay wiring ➤Replace traditional latching relays ➤Replace traditional indicating panel lights ➤Replace external timers Eliminate traditional panel control switches with: ➤12 programmable operator control pushbuttons ➤16 local control points Program operator control pushbuttons to implement your control scheme via SELOGIC control equations. Change operator control pushbutton labeling to suit your control scheme (see Figure 11 ). Local control points are accessed via the front-panel human-machine interface and display (see Figure 11 ). They are in a sense “hidden/extra” operator control push- buttons. Set, clear, or pulse local control points with the front-panel human-machine interface pushbuttons and display. Program the local control points to implement your control scheme via SELOGIC control equations. Use the local control points for such extra functions as trip testing or scheme enabling/disabling. Eliminate RTU-to-relay wiring with 32 remote control points. Set, clear, or pulse remote control points via serial port commands. Incorporate the remote control points into your control scheme via SELOGIC control equations. Use remote control points for SCADA-type control oper- ations (e.g., trip, close, settings group selection). Replace traditional latching relays for such functions as “remote control enable” with 32 latching control points. Program latch set and latch reset conditions with SELOGIC control equations. Set or reset the latching con- trol points via operator control pushbuttons, control inputs, remote control points, local control points, or any programmable logic condition. The latching control points retain states when the relay loses power. In the factory settings, these latching control points are what give many of the operator control pushbuttons their “enable/disable” or “on/off” mode of operation, where each press of the pushbutton toggles the latch to the opposite state. Replace traditional indicating panel lights with 24 status and target LEDs. Change LED labeling to suit your con- trol scheme (see Figure 11). Note that the aforemen- tioned 12 programmable operator control pushbuttons also have programmable LEDs associated with them. Define custom messages (e.g., SINGLE PHASE TRIP ENABLED) to report power system or relay conditions on the LCD. Control which messages are displayed via SELOGIC control equations by driving the LCD display via any logic point in the relay. Up to 32 programmable display messages can be set. Eliminate external timers for custom protection or con- trol schemes with 64 general purpose SELOGIC control equation timers. Each timer has independent time-delay pickup and dropout settings. Program each timer input with any desired element (e.g., time qualify a voltage ele- ment). Assign the timer output to trip logic or other con- trol scheme logic. The SEL-651R also features 16 general purpose up/down counters. Such counters can be used to emulate motor-driven timers, which can stall in place indefinitely and then continue timing when appro- priate user-set conditions are present. SEL-651R Data Sheet Schweitzer Engineering Laboratories, Inc. 10 SELOGIC Control Equations With Expanded Capabilities Expanded SELOGIC control equations puts relay logic in the hands of the protection engineer. Assign the relay inputs to suit your application, logically combine selected relay elements for various control functions, and assign outputs to your logic functions. Programming SELOGIC control equations consists of combining relay elements, inputs, and outputs with SELOGIC control equation operators (see Table 2 ). Any element in the Relay Word can be used in these equa- tions. The SEL-651R is factory set for use without addi- tional logic in many situations. For complex or unique applications these expanded SELOGIC functions allow superior flexibility. Add programmable control functions to your protection and automation systems. New func- tions and capabilities enable you to use analog values in conditional logic statements. ACSELERATOR QuickSet SEL-5030 With Design Templates Use the ACSELERATOR QuickSet SEL-5030 Software to develop settings off-line. The system automatically checks interrelated settings and highlights out-of-range settings. Settings created off-line can be transferred by using a PC communications link with the SEL-651R. The software converts event reports to oscillograms with time-coordinated element assertion and phasor/sequence element diagrams. The QuickSet interface supports Win- dows 95, 98, 2000, and NT operating systems. View real- time phasors via QuickSet. QuickSet allows users to author personalized application designs. Use application designs within QuickSet to quickly implement advanced schemes such as automatic network reconfiguration and single-phase trip- ping/reclosing. Application Designs hide settings you do not want changed (e.g., SELOGIC control equations), while making visible just the minimum necessary set- tings (e.g., timer and pickup settings) to implement the scheme. All settings can be aliased and manipulated mathematically for simple end-user interfacing. Custom notes and settings ranges can also be defined. These Application Designs also enhance security, allowing access to only a specified group of settings. Create Application Designs that include the most commonly used relay features and settings (see Figure 9 ) and watch commissioning times drop drastically. Quickly commission recloser controls by using just the settings you need. Design custom templates using the licensed version of QuickSet for your specific applica- tions. Templates are stored on the recloser control for easy access when making settings changes. Figure 9 Example Application Designs MIRRORED BITS Communications The SEL-patented MIRRORED BITS communications technology provides bidirectional recloser control-to- recloser control digital communications. MIRRORED BITS can operate independently on up to two EIA-232 serial ports on a single SEL-651R. With MIRRORED BITS oper- ating on two serial ports, there is communication upstream and downstream from the SEL-651R site. Table 2 SEL OGIC Control Equation Operators Operator Type Operators Comments Boolean AND, OR, NOT Allows combination of measuring units. Edge Detection F_TRIG, R_TRIG Operates at the change of state of an internal function. Comparison >, >=, =, <=, <, < > Precedence Control ( ) Allows multiple and nested sets of parentheses. Comment #Provides for easy documentation of control and protection logic. Schweitzer Engineering Laboratories, Inc.SEL-651R Data Sheet 11 Figure 10 MIRRORED BITS Transmit and Receive Bits This bidirectional digital communication creates eight additional virtual outputs (transmitted MIRRORED BITS) and eight additional virtual inputs (received MIRRORED BITS) for each serial port operating in the MIRRORED BITS mode (see Figure 10). Use these MIRRORED BITS to transmit/receive information between upstream relays and downstream recloser control to enhance coordination and achieve faster tripping for downstream faults. MIR- RORED BITS technology also helps reduce total scheme operating time by eliminating the need to assert output contacts to transmit information. Serial Port Communications The SEL-651R is equipped with four independently operated serial ports: one EIA-232 port on the front and three EIA-232 ports on the rear. The recloser control does not require special communications software. Use any system that emulates a standard terminal system. Establish communication by connecting computers, modems, protocol converters, printers, an SEL-2020, SEL-2030, or SEL-2032 Communications Processor, SCADA serial port, and/or RTU for local or remote com- munication. SEL manufactures a variety of standard cables for con- necting this and other IEDs to a variety of external devices. Consult your SEL representative for more infor- mation on cable availability. Additional Features Status and Trip Target LEDs/Operator Controls The SEL-651R Recloser Control includes 24 program- mable status and trip target LEDs, as well as 12 program- mable direct-action operator control pushbuttons on the front panel. These targets are shown in Figure 11 and explained in Table 4. The SEL-651R features a versatile front panel that you can customize to fit your needs— even LED colors can be changed (if tri-color LEDs are ordered). Use SELOGIC control equations and slide-in configurable front-panel labels to change the function and identification of target LEDs and operator control pushbuttons and LEDs. Functions are simple to config- ure using QuickSet software. Label sets can be printed from a laser printer using templates supplied with the relay or hand labeled on supplied blank labels.

SEL-651R Data Sheet Schweitzer Engineering Laboratories, Inc. 14 Control Inputs and Outputs Besides the dedicated trip/close outputs that exit the SEL-651R on a control cable receptacle/interface at the bottom of the enclosure (see Figure 6 ), the basic SEL-651R includes two Form C (normally closed/nor- mally open) standard-interrupting output contacts: OUT201 and OUT202 (row 200; see Figure 14 ). OUT201 is programmed as an alarm output from the fac- tory. The following additional input/output (I/O) can be ordered (row 100; see Figure 14): ➤Optoisolated inputs IN101–IN107 (12 Vdc rating; IN106 and IN107 share a common terminal) ➤Form A (normally open) standard-interrupting out- put contacts OUT101–OUT105 ➤Form C (normally closed/normally open) standard- interrupting output contacts OUT106–OUT108 Assign the optoisolated inputs for control functions, monitoring logic and general indication. Set input debounce time independently for each input. Each output contact is programmable using SELOGIC control equa- tions. Monitoring and Metering Event Reporting and Sequential Events Recorder (SER) Event Reports and Sequential Events Recorder features simplify post-fault analysis and help improve your understanding of both simple and complex protective scheme operations. These features also aid in testing and troubleshooting relay settings and protection schemes. Access settings, events, and other data over a single com- munications link to increase availability of information. Event Reporting and Oscillography In response to a user-selected internal or external trigger, the voltage, current, and element status information con- tained in each event report confirms relay, scheme, and system performance for every fault. Decide how much detail is necessary when an event report is triggered: 4 samples/cycle or 32 samples/cycle resolution analog data. The relay stores: ➤40 event reports (when event report length is 15 cycles) ➤25 event reports (when event report length is 30 cycles) Reports are stored in nonvolatile memory. Relay settings operational in the relay at the time of the event are appended to each event report. The SEL-5601 Software and QuickSet software can read a Compressed ASCII version of the event report, which contains even more information than the standard ASCII event report. With this software, oscillographic traces and digital element traces can be produced on the PC dis- play. A phasor analysis screen allows the protection engi- neer to analyze the prefault, fault, and postfault intervals, observing both the directly measured inputs, as well as the calculated sequence component signals. Event Summary Each time the relay generates a standard event report, it also generates a corresponding Event Summary. This is a concise description of an event that includes the follow- ing information: ➤Relay/terminal identification ➤Event date and time ➤Event type ➤Fault location ➤Recloser shot count at time of trigger ➤System frequency at the start of the event report ➤Front-panel fault targets at the time of trip ➤Phase (IA, IB, IC), ground (IG = 3I0), and nega- tive-sequence (3I2) current magnitudes in amps primary measured at the largest phase current mag- nitude in the triggered event report With an appropriate setting, the relay will automatically send an Event Summary in ASCII text to one or more serial ports each time an event report is triggered. Sequential Events Recorder (SER) Use this feature to gain a broad perspective of relay ele- ment operation. Items that trigger an SER entry are selectable and can include input/output change of state, element pickup/dropout, recloser state changes, etc. The relay SER stores the latest 1,000 entries. Voltage Sag/Swell/Interrupt (SSI) Report The voltage sag/swell/interrupt (SSI) report captures power quality data related to voltage disturbances over a long period of time. Data captured includes the magni- tude of currents, one set of three-phase voltages, a refer- ence voltage, and the status of the voltage sag/sell/interrupt (VSSI) elements (Relay Word bits). Schweitzer Engineering Laboratories, Inc.SEL-651R Data Sheet 15 SSI report information is useful for analyzing power quality disturbances, or protective device actions that last longer than the time window of a conventional event report. The SSI recording rate varies from fast to slow, depending on changes in the triggering elements. SSI data (a minimum of 3855 entries) is stored to nonvolatile memory just after it is generated. Recloser Wear Monitor Reclosers experience mechanical and electrical wear every time they operate. The recloser wear monitor mea- sures unfiltered ac current at the time of trip and the number of close-to-open operations as a means of moni- toring this wear. Every time the recloser trips, the recloser control records the magnitude of the raw current in each phase. This current information is integrated on a per phase basis. When the result of this integration exceeds the threshold set by the recloser wear curve (see Figure 13 ), the SEL-651R asserts a logic point for the affected phase. This logic point can be routed for alarming or to modify reclosing (e.g., shorten the number of reclosures). This method of monitoring recloser wear is solidly based on methods of breaker rating from switchgear manufactur- ers. Figure 13 shows three setpoints needed to emulate a breaker wear curve. If the user wants to customize the recloser wear curve, the setpoints in Figure 13 can be programmed. Predetermined setpoints are available for traditional reclosers, following recommendations for reclosers in ANSI C37.61-1973. Figure 13 Recloser Contact Wear Curve and Settings Metering The SEL-651R provides extensive and accurate metering capabilities, as shown in Table 5 . See Specifications for metering accuracies. The recloser control reports all metered quantities in primary quantities (current in A primary and voltage in kV primary). THD elements for the current and voltage channels are available for har- monics-based decisions or operations. The phantom voltage feature creates balanced three- phase voltage values for metering from a single-phase voltage connection. These derived three-phase voltage values are also used in three-phase power and energy metering. kA Interrupted (Set Point 1) (Set Point 2) (Set Point 3) Breaker Manufacturer's Maintenance Curve Close to Open OperationsTable 5 Available Metering Quantities (Sheet 1 of 3) Instantaneous Quantities Fundamental Values Currents IA,B,C,N Phase and neutral current channels IG Ground (residual current) I1, 3I2, 3I0 Positive-, negative-, and zero- sequence Voltages Values for both VY and VZ three-phase voltage channels VA,B,C, AB, BC, CA Line-neutral and line-line V1, V2, 3V0 Positive-, negative-, and zero- sequence Power MWA,B,C,3P Megawatts, single- and three- phase MVARA,B,C,3P Megavars, single- and three- phase MVAA,B,C,3P Megavolt-amps, single- and three-phase PFA,B,C,3P Power factor, single- and three- phase (with leading or lagging indication) Demand Quantities Present and Peak (Fundamental Values) Currents IA,B,C,N Phase and neutral current channels IG Ground (residual current) 3I2 Negative-sequence Power MWA,B,C,3P Megawatts, single- and three- phase (in and out) MVARA,B,C,3P Megavars, single- and three- phase (in and out) MVAA,B,C,3P Megavolt-amps, single- and three-phase Energy Quantities In and Out (Fundamental Values) MWhA,B,C,3P Megawatt hours, single- and three-phase MVARhA,B,C,3P Megavar hours, single- and three-phase SEL-651R Data Sheet Schweitzer Engineering Laboratories, Inc. 16 Load Profile The load profile recorder in the SEL-651R is capable of recording up to 15 selectable analog quantities at a peri- odic rate (5, 10, 15, 30, or 60 minutes) and storing the data in a report in nonvolatile memory. Choose any of the analog quantities listed in Table 5 (except peak demands). At a five-minute periodic recording rate and with 15 selected analog quantities, up to 26 days of load profile data can be stored. The greater the periodic recording rate or the lesser number of selected analog quantities, the greater the number of days of storage available.
