The case outline and mounting dimensions are shown in Figure 3–2: FRONT AND REAR VIEW on page 3–2.
  • Page 17: Ground Distance Quadrilateral Characteristics

    1.2.4 GROUND DISTANCE QUADRILATERAL CHARACTERISTICS The ALPS relay has been modified to include the option to use either quadrilateral characteristics or variable Mho charac- teristics for all zones of ground distance protection. The model numbers affected by this modification are: ALPSD- B XXXXXXXXX (where X may be any valid character) with firmware version V0005.00AA00 or higher.
  • Page 18 1 PRODUCT DESCRIPTION Figure 1–1: GROUND DISTANCE QUADRILATERAL CHARACTERISTIC In the ALPS relay the four straight lines of the quadrilateral characteristic are developed by a combination of the following three characteristics: Reactance characteristic (section 1). The tilt of the reactance characteristic is determined by the characteristic timer setting.
  • Page 19 This might also occur for a remote fault when the relay is located near a strong source. Therefore, if the phase voltage is less than the minimum threshold voltage, the positive-sequence memory voltage from the ground Mho functions is used in place of the phase voltage to polarize the directional function.

  • Page 20: Line Protection Schemes

    1.2.5 LINE PROTECTION SCHEMES The ALPS provides four zones of distance protection with overcurrent backup functions. The ALPS is a highly flexible sys- tem: along with predefined protection schemes, it also has the ability to be programmed by the user. The custom program- mability of the ALPS is discussed in the next section.

    ALPS issues a trip. If the ALPS issues a trip, then a normal fault report is stored as part of the oscillography data. If the ALPS does not issue a trip, a pseudofault report is created. The trip type is listed as OSC, the trip time is set to when the OSC Trigger occurred, the operating time is set to zero, and the fault type and location are computed, based on post-OSC Trigger data.

    1.5.9 EQUIPMENT DUTY When the ALPS is applied with a single breaker, it incorporates the ability to monitor the number of breaker operations and the breaker duty. Alarm levels can be set for both the total number of breaker operations and the total equipment duty. See Section 2.2.4: EQUIPMENT DUTY on page 2–6 for a complete description of the Equipment Duty feature.
  • Page 30: Time Synchronization

    IRIG-B signal connected to the IRIG-B terminals, located on terminal block “D” on the rear panel, may be used to synchronize the clock. The clock in a given ALPS is synchronized to within ±1 ms of any other ALPS clock, if the two relays are wired to the same synchronizing signal.
  • Page 31: Alarms

    Operation of the Trip Circuit Monitor causes a noncritical alarm event. If one or more breaker poles are opened in some manner other than by a trip issued by the ALPS, then the 52/a contact normally wired in series with the trip coil opens and drops the voltage across the open contact to zero.
  • Page 32: Keypad And Display

    The DTA provides either a nominal 0 to 1 mA DC output or a nominal 0 to 5 V DC output. The choice of output ranges is made by a switch located on the Processor Board. The Processor Board must be removed from the ALPS chassis to access this switch.
  • Page 33: Start-Up Self-Tests

    A reset is not reported by the ALPS. If the reset is successful no failure status is recorded and the critical alarm output is not energized; however, during the reset procedure, the red LED on the front panel is lit and a failure code may appear on the display.
  • Page 34: Continuous Monitor

    The ALPS relay includes a Continuous Monitor feature in addition to its self test features. The Continuous Monitor is intended to detect any ALPS tripping units (Zone 2 or Zone 3 distance functions, 50G or 50 overcurrent functions) that are in the picked up condition without a corresponding operation of the Fault Detector.

    ALPS single phase and three phase models, respectively. Since this non-pilot scheme overlays the other protection schemes in the ALPS, it is in essence a part of all of them. The Zone 1 distance functions are set to reach no greater than 90% of the positive-sequence impedance of the protected line.

Some blocking schemes use frequency-shift tone channels, such as the GE type NS40A. For a three-terminal application employing FSK tones, each terminal has two receivers and an additional contact converter must be assigned.

  • Page 47: Single Phase Tripping

    PHASE SELECTION When used in a single phase tripping application, the ALPS is designed so that only the faulted phase will be tripped for a single line to ground fault, but all phases will be tripped for any multi-phase fault. To accomplish this goal, the ALPS includes a faulted phase determination algorithm.
  • Page 48 OPEN POLE DETERMINATION The ALPS includes logic to detect when one or more poles of the circuit breaker is open. This logic is depicted in Figure 1– 21: OPEN POLE DETECTION LOGIC on page 1–41. The logic uses a combination of current and voltage detectors and breaker auxiliary contacts.
  • Page 49 RECLOSE CONTROL The ALPS includes two Reclose Initiation outputs. RI-1P picks up when the ALPS selects to trip only one of the three phase trip outputs. RI-3P picks up whenever the ALPS selects to trip all three poles of the breaker. As shown on Figures 1–23: OST MHO CHARACTERISTIC on page 1–42 and 1–24: OUT-OF-STEP TRIPPING LOGIC on page 1–42, the Reclose Ini-...
  • Page 50: Description

    This solution requires multiple communications channels to transmit the information between the substations. The ALPS relay offers two phase identified channel solutions to the problem. The first requires the use of two permissive chan- nels with encoding; the second requires the use of four permissive channels. The operation of these schemes is described in the following section.
  • Page 51 S substation will sent detect an AG fault and send channel 1 to the remote terminal. The ALPS relay at Substation R will detect an ABG fault, and will send both channels 1 and 2 to the relay at S. The ALPS relay at Substation S will issue a sin- gle pole phase A trip via the operation of the Zone 1 ground distance function.
  • Page 52: Four Channel Phase Identified Channel Logic

    AG fault and sends channel 1 to the remote terminal. The ALPS at Substation R detects an ABG fault and sends channel 4 to the relay at S. The ALPS at Substation S issues a single pole phase A trip via the operation of the Zone 1 ground distance function.
  • Page 53: Description

    The OST function does not have a dedicated output relay, nor does it automatically initiate tripping via the ALPS trip output relays. Rather, the output of the OST logic must be assigned by the user to an output relay, or to the configurable trip bus input (CNFTRP, Index #122) if it is desired to trip the same circuit breaker as for a line fault.

    If both an OSB and OST are detected, the data is stored based on the OST operation. Only one OS data file is stored in the ALPS. Once the data is captured, it will not be overwritten until it is retrieved from the ALPS, or cleared by an OS data reset Action command.

    1POLE3POLE if both modes of reclosing are to be used. If the ALPS is set for single-pole tripping and the recloser is set to 3POLE, then the recloser will issue the three-pole trip enable signal to tell the ALPS to trip three-pole regardless of the fault type, and the recloser will be immediately sent to lockout following any trip.
  • Page 59: Recloser Outputs

    All of the recloser outputs are programmable. To use any of these outputs externally, insure that an appropriate output relay is assigned to each of the used outputs. Assignment can be made through ALPS-Link, Xpression Builder, or the keyboard. The following outputs are provided: a) CLOSE The close output controls reclosing of the breaker.
  • Page 60: Synchronism Check (Optional)

    The synchronism check function requires voltage inputs from both the BUS and LINE side of the circuit breaker in order to operate. The ALPS requires three phase potential for proper operation of its protective functions; this three phase voltage may be supplied from either the bus or the line. In addition to this three phase potential, the synchronism check function requires a single phase voltage from the other side of the breaker.

  • Page 66: Configuration

    102: SYSFREQ - System Frequency SYSFREQ establishes the operating frequency of the ALPS. It can be set to either 50 Hz or 60 Hz. When this setting is changed it will only be implemented after turning the DC power off and then on.
  • Page 67 Figure 2–1: TRIP CIRCUIT MONITOR The trip contacts are also monitored when a trip is initiated by the ALPS. If the voltage across the contacts does not drop when the trip is initiated, it is assumed that the trip circuit is not intact and an alarm is issued. If the voltage does drop con- currently with the trip initiation, the trip circuit is considered to have been activated and no alarm is issued.
  • Page 68: Communications

    Output As an example, if you are using an ALPS with three phase tripping, and if outputs T1 and T3 are to be monitored and T2 and T4 are not, the following setting would be used: NUM_MON = 0101 This setting is entered in to the relay from the LUI in decimal format (that is, NUM_MON = 5).
  • Page 69 The baud rate setting of 300, 1200, 2400, 4800, or 9600, must be set to match the baud rate of the modem or serial device connected to the serial port of the ALPS relay system. The parity and stop bits must match those selected for the serial port of the remote PC.

  • Page 76 This setting prevents the Zone 1 functions from producing an output if the respective blocking functions have operated. This type of operation is required when series capacitors are located behind the ALPS system as shown in Figure 2–3: POWER SYSTEM ONE LINE DIAGRAM WITH SERIES CAPACITORS on page 2–10. For this situation, the voltage applied to the system would reverse for a fault beyond the capacitors if gap flashing were not to occur or if the MOV protec- tion did not conduct significantly.

    2.3.5 Z4DISTANCE The settings to be used on the Zone 4 distance functions in the ALPS system depend on the application and the scheme selected. Both the phase and ground distance functions can be set to look in the reverse direction relative to the Zone 1, Zone 2 and Zone 3 phase and ground distance functions (see below).
  • Page 83 Figure 2–10: ZONE 4 FAULT EXAMPLE The ALPS Zone 4 phase distance functions are not provided with offset since they use an adaptive memory feature to pro- vide the operation needed for bolted three-phase faults at the relay location. The adaptive memory works as follows: If the fault voltage is less than 10% of rated voltage then the voltage prior to the fault will be used to polarize the Zone 4 functions.

    Hayes. This is necessary since the ALPS-Link communications software that runs on the PC sends a Hayes-com- patible command string to the modem located at the PC. The ALPS does not send any configuration commands to its modem. Both the relay modem and the PC modem must be uniquely configured to permit logging into and communicating with the relay using ALPS-Link software.
  • Page 227: Pc Modem

    The modem will operate properly without these two settings, but it will not hang up if the appropriate handshaking signal is lost. An ALPS-Link setting establishes the baud rate, which must match the ALPS baud rate setting. ALPS-Link will then set the specified PC serial port (COM1, COM2) to the proper baud rate, parity, data bits, and stop bits.

  • Page 294 Saving data in the DAFF format creates an OSC, DAF, and REP file. The OSC file is used to playback a waveform to the relay. The DAF file is used by the GE-DATA program to view the waveforms and flags within the relay. The REP file con- tains the fault report and settings in the relay at the time of the fault.
  • Page 295: Description

    Baud Rate for RS485/RS232 port are configurable from the MMI of the ALPS. There will be a delay before the ALPS is ready to answer Modbus requests from the Modbus master on power up. This is due to internal data and baud rate synchronized tasks to be performed. Device address changes and baud rate changes will affect the operation of the device once the device is communicating.
  • Page 296: Exception Or Error Replies

    B.1.4 EXCEPTION OR ERROR REPLIES When a system host command received by an ALPS cannot be performed, it replies with an error code. This is different from detecting communication related errors, such as a CRC error, for which the ALPS ignores the command.
