  • GENERATORS MAINTENANCE
  • Typical Generator Maintenance
  • Generators
  • System controls
  • REASONS WHY GENERATORS FAIL
    FOREIGN OBJECT DAMAGE
    Problem: Objects can come from external sources or
    failure of internal components, they can pick up energy
    from the spinning rotor and do extensive damage
    Prevention: Inspect on a regular basis all internal parts
    that are prone to failure or can be dislodged.
    Inspection tests can be a combination of visual
    inspection along with ultrasonic or magnetic particle
    tests on rotating components
  • STATOR WINDING VIBRATION
    Problem: Primarily a design related problem that
    affects large (>300Mw) generators which have
    insufficient end winding bracing to limit the
    movement of end turns.
    Prevention: Proper bracing of the end winding is
    required to limit motion caused by steady state and
    transient electromagnetic forces.
  • ROTOR WINDING DISTORTION
    Problem: Rotor winding distortion caused by poor end
    turn blocking support design or by foreshortening of
    the rotor coils. Foreshortening is caused by thermal
    forces which compress rotor coils.
    Prevention: Proper design of rotor coils and bracing to
    support the coils under axial load is essential.
    Rotors should be tested for turn to turn shorts at
    operating speed.
  • STATOR WINDING VIBRATION
    Problem: Primarily a design related problem that
    affects large (>300Mw) generators which have
    insufficient end winding bracing to limit the
    movement of end turns.
    Prevention: Proper bracing of the end winding is
    required to limit motion caused by steady state and
    transient electromagnetic forces.
  • OVERHEATING
    Problem: Overheating of the rotor or stator can lead to
    insulation failure, shorting of turns and ground
    faults. Overheating can result from blocked
    ventilation passages caused by shifting insulation
    components or slot wedges.
    Prevention: Inspect on a regular basis to ensure all rotor
    wedges are "locked" in place preventing migration
    and thus blocking of cooling passages.
  • CONTAMINATION
    Problem: For air cooled machines, dirt and dust cause
    tracking which can lead to electrical ground faults.
    Prevention: Inspect air filterson a regular basis , the
    filters must be checked and cleaned regularly.
    Polarization index (PI) tests give a good indication of
    overall cleanliness of the rotor winding.
  • ROTOR VIBRATION
    Problem: There are many causes, turn-to-turn shorts,
    rotor coil foreshortening, electrical grounds,
    mechanical imbalances, overheating, etc.
    Prevention: Comprehensive vibration measuring is effective
    combined with a regular maintenance program.
  • STATOR WEDGE LOOSENESS
    Problem: When stator wedges become loose, coils can
    vibrate causing insulation wear leading to ground
    faults or turn-to-turn shorts.
    Prevention: Inspect on a regular basis tightness of
    wedge blocks.
  • STATOR CORE DAMAGE
    Problem: Stator core looseness can occur over time as
    pre-tensioned through bolts relax. A loose core
    results in insulation wear to coils and laminations
    resulting in hot spots and core-to-coil failures.
    Prevention: Inspect bolt tightness on a regular basis.
  • GENERATOR MAINTENANCE
    The following tests which should be carried out annually in addition to vendor recommended maintenance.
  • A) INITIAL GENERATOR TEST
    • “Megger” rotor winding
    • “Megger” exciter armature winding
    • “Megger” exciter field winding
    • Complete polarization index (pi) on main stator
    • Check bearing insulation
  • B) INSPECTION ON STATIC EXCITER
    • Remove exciter end cover
    • Examine condition of diode carrier
    • Examine exciter armature/stator for contamination
    • Examine exciter armature/stator for winding wear
    • Check pmg magnets for contamination
  • C) ELECTRICAL CONTROL/PROTECTION PANEL
    • Visually inspect external surfaces of panel
    • Complete insulation resistance checks of panel wiring
    • Check function of all relays
    • Check all fuses
    • Check all lamps
    • Check operation of all switches
    • Check operation of panel heaters
    • Run generator; recalibrate avr
    • Secondary inject all protective relays
  • E) ROTOR EARTH FAULT PROTECTOR
    • Carry out static checks to confirm operation of
    detector
    • Carry out functional check to confirm operation of
    detector
  • F) SLIP-RINGS AND BRUSH-GEAR (IF FITTED)
    • Check all brushes for grade and length
    • Check condition of brush holders/mountings
    • Check that spring tensions are correct
    • Check conditions of slip-rings
    • Check mechanical run-out of slip-rings
    • Check cooler and leakage alarms
