Welcome & Introductions

8:00-8:30 AM

Generator Protection
Instructor: Wayne Hartmann

(Based on IEEE C37.102)

Generators are subject to internal faults, external faults and abnormal operating conditions impressed by the turbine and excitation system issues, as well as power system events the generator has no control over but must cope with. False (nuisance) trips are costly as the generators output is lost. Inability to trip due to lack of sensitivity, lack of certain protections or deficiencies in protection application may cause severe damage to generators, resulting in prolonged outage and revenue loss, plus increased system instability risk. Achieving the ideal balance of secure and dependable protection involves use of an array of elements that protect the generator for all operating modes: off-line, start up, synchronizing, various levels of power output and when challenged by system faults and anomalies.

    • Abnormal Frequency (81-U, 81A)
    • Inadvertent Energizing (50/27)
    • Blown VT Fuses (60FL)
    • Breaker Failure/Pole Flashover (50BF)
    • Loss of Prime Mover (32)
