Advanced AC Generators

On completion of the course, delegates will:

• How does a generator function?
• Why is it designed as it is?
• What happens if the generator is synchronized out-of-phase?
• What happened in the control room such that one would make such a large error when synchronizing
• How can we avoid such an error?
• Just how bad (and what is) negative phase sequence currents?
• Corona discharge what does that mean?
• How do you repair fused stator punchings?
• What components should be high-potential tested?
• How can we avoid accidental injury when testing the generator?
• What are the probable causes of grounded fields?
• Why have we (recently) heard of hydrogen explosions? How do we avoid?

• Generator functions.
• Active and reactive power.
• The major components used in the construction of an AC generator.
• Operation and maintenance of the most common excitation systems.
• A speed governor alters generator output in response to a frequency deviation.
• The role of the governor is response to this speed/frequency change).
• The voltage regulator alters generator output in response to a voltage deviation.
• The causes and effects of both voltage and frequency oscillations and the impact they each
  have on power system dynamics.
• Generator normal/safe startup and shutdown procedures.
• the generator synchronizing process is as it is
• Abnormal generator operation and recommended actions for generator protection.
• The major activities associated with generator maintenance.
• Proper generator disassembly and reassembly sequences.
• The procedures for cleaning generator components.
• The procedures for inspection of generator components.
• Generator component, the types of damage that might be found, and what probable causes of that damage are.
• The various repair methods for defective component condition.
• Electrical tests commonly performed on large AC generators.
• The procedures for the various generator tests.
• Safety precautions for the conducting of these electrical tests
