GENERAL DESCRIPTION The SMOR system is a microprocessor based multifunction protection, control and measurement unit. The SMOR uses a set of algorithms to create a general purpose protection and monitoring unit for power systems.

  • Page 13: Voltage Units

    GEK-105593C To protect against loss of polarization voltage, the system includes adjustable fuse-failure logic. This logic allows to either block the operation of the units or to convert the directional units into non-directional. The selection is done through a setting. The fuse failure function operates on two different conditions (OR logic): - Operation of undervoltage detectors (adjusted at 3.5 volts) - Activation of a digital input connected to the voltage MCB.

    GEK-105593C 2.2.6. PHASE ROTATION SEQUENCE SELECTION The SMOR system works correctly with any phase sequence selection ABC or CBA without the need to change the wiring of the external transformers, since there is a setting which allows the selection of the phase rotation sequence.
  • Page 18: Analysis Functions

    GEK-105593C 2.3. ANALYSIS FUNCTIONS. The SMOR system includes an event recorder and an oscillographic recorder with 1 msec. time tag resolution. So as not to lose the date and time setting or the oscillographic recorder information, the unit uses a capacitor as backup for the internal clock and register memory. This allows the information to be kept for at least 24 hours from the moment the power supply is lost.

  • Page 23: Recloser

    GEK-105593C 2.4.3. RECLOSER The SMOR system recloser allows up to 4 attempts to reclose the line breaker. For each of these attempts it is possible to set independently the time that should elapse before the reclosing order is issued. In addition, it is possible to set which functions can initiate the recloser, and, after a given reclosing, which functions can trip the breaker again.
  • Page 24 GEK-105593C Recloser logic. Figure 5, which shows the states diagram of the recloser, will help to understand this section. For those who are not familiar with this type of representation the following paragraphs give a summary of how a states diagram works.

    "TABLE SELECTION-1" which allow up to 4 combinations from 0 to 3. To do this it is necessary to configure (using GE-INTRO software) two inputs to have these meanings. For applications which require less tables (up to 2) it is possible to use only one input.
  • Page 27: Time Synchronization

    The SMOR system has 6 digital inputs (two groups of 3 inputs with one common in each group). The inputs can be configured by the user by means of the GE-INTRO configuration program. Using the optional expansion board it is possible to increase the number of inputs up to a total of 12 (4 groups of 3 inputs with one common in each group.
  • Page 28: Outputs

    The model with optional expansion board has 4 more outputs, which are configurable and electrically separate. (See external connections in figure 7) The outputs are configured using the GE-INTRO configuration software. The technical characteristics of the outputs are shown in section 4.
  • Page 29: Man-Machine Interface (Mmi)

    Gate 1 (PORT 1 and PORT 2 connectors) and 2 (PORT 3 connector) are independent and the unit can serve them simultaneously. The communications protocol is the same as that used for the rest of the GE digital protection systems and requires the use of the GE-LOCAL software. The instruction book for this program, which facilitates dialogue with the relay, is supplied with the unit.
