    4 Protection Functions Differential Zone Selection and CT Input Assignment The B-PRO can be configured for a number of different differential zones. These zones are defined as: • Bus1 • Bus1 and Transformer • Transformer Only • Bus1 and Bus2 Bus1 zone allows up to 6 current inputs to be used in the bus differential zone (87B-1).
  • Page 46 IR (pu) Figure 4.2: Bus Differential Characteristic CT Saturation The B-PRO bus protection includes a significant improvement to the tradition- Detector al two slope differential characteristic that provides immunity to CT mismatch and minimal CT saturation sensitivity for external faults. The CT saturation de- tector detects all CT saturation conditions for external faults and blocks the dif- fferential protection from operating.
  • Page 47 When enabled, you set a timer to control how long you want an external CT saturation condition to block the differential protection. Normally you would set this timer to be slightly longer than your maximum clearing time for an ex- ternal fault. D01908R02.12 B-PRO User Manual 8700...

    • Recorder triggering by any internal logic or external input signal Swing Recording The B-PRO records dynamic system responses allowing you to analyze system stability and to provide a larger context for fault analysis. Swing records con- tain positive sequence phasor measurements and system frequency calculated at a rate of 1 phasor per cycle.
  • Page 66 The B-PRO compresses records on the fly, achieving a typical lossless com- pression rate of 4:1. As a result, the B-PRO can store up to 30 seconds of fault recordings and up to 24 minutes of swing recordings in non-volatile storage. If the storage is full, new records automatically overwrite the oldest, ensuring that the recording function is always available.

  • Page 151: Appendix K Bus Differential Function Setting Examples

    The B-PRO Bus Protection Relay provides low-impedance differential protec- tion for transmission and distribution buses, for up to 6 three-phase inputs. The B-PRO is a per-unit based relay, meaning all secondary currents entering the relay are converted to per-unit values for protection calculations. Choosing the correct per-unit base for the current permits the development of standard pro- tection settings that work for most bus protection applications.
  • Page 152 Appendix K Bus Differential Function Setting Examples While performing setting calculations for the B-PRO, the IO operate current is calculated by the equation: The restraint current IR calculation is: Settings Philosophy The recommended settings method described in this technical note is simple: choose the MVA Base setting of the relay such that the maximum bus transfer load current is equal to the IRs setting in per-unit current.
  • Page 153 3. Choose a value for IRs 4. Calculate the Bus Base MVA 5. Determine the CT Saturation Block Timer 6. Enter settings in the B-PRO 1. Enter Winding/CT Connection Information Enter Winding and CT connection information to match the specific bus pro- tection application, as in the example of Figure 4.
  • Page 154 The IRs setting determines the break point between the slope S1 and slope S2. The IRs setting is also the upper limit of the load range of the B-PRO. For this recommended settings method, the maximum bus transfer current is equal to IRs in per-unit current.
  • Page 155 Appendix K Bus Differential Function Setting Examples Figure K.6: System Parameters settings The maximum relay setting for the Bus Base MVA in the B-PRO is 10000 MVA. If the calculated Bus Base MVA exceeds this value, choose the next higher whole number value for IRs (3 per-unit in this example), and re-calcu- late the Bus Base MVA.
  • Page 156 320 - 0 = 320 primary amps. On a 1200 A base this is 0.27 per-unit, which is above the recommended setting for IOmin, namely 0.25 per-unit. For this case, it is recommended to set IOmin to 0.4 per-unit in order to prevent possible false tripping of the bus. Appendix K-6 B-PRO User Manual 8700 D01908R02.12...
