If you need to test the nature of the protection relay DFS (Dynamic Fault Simulator)

Summary

DFS is a tester that automatically re-creates the protection relay with a built-in voltage and current
waveform that simulates any failure that it will experience in future driving.

  • Interlinked signal generator (Omicron)
  • Automatic analysis of signal generation and corresponding protection relay operation for testing protection relay characteristics
  • Analysis of data on the occurrence of 4 protective relay in actual operation through IEC61850 communication protocol
  • Completion of site field test KHNP(Korea Hydro & Nuclear Power Co.,Ltd.) / Completion of verification of KEPCO
    Research Instiitute Protected Relay Demonstration Center

Necessity

Errors still occur despite the reliability performance test, of which its engineering costs are high-priced

  • Protection relay that secures equipment in the event of a power plant failure have a variety of facilities in need of protection, and the system in
    which relays are installed is complicated
  • Even if the reliability verification test is performed by setting the well-designed system and the well-calculated set value, the damage is enlarged
    due to the malfunction due to the insufficient error in the reliability verification test performed before the normal operation of the protection relay.
  • The protective relay is a facility that must be driven with 100% complete reliability prior to normal operation, and this error must be corrected in advance.
  • All power companies are performing reliability verification while paying engineering costs that are several times higher than the value of the protective relay to establish a 100% complete protection system; however, errors still occur.
  • In the event of a power facility failure in the power system, the damage caused by malfunctioning the protective relay is minimal, ranging from hundreds of millions to hundreds of billions.
  • Existing protection relay reliability verification tests are limited to test levels that characterize whether the protection relay operates as set rather
    than simulating a failure condition.
