Power Generators and Voltage Regulators



Power Generators and Voltage Regulators

Description
This three days technical training includes a detailed study of power generators and voltage regulators, and the interaction between the two. The training also provides a solid understanding of generator paralleling, VAR flows, and generator/regulator response to changing loads and system voltages. A good working knowledge of poly-phase AC theory is recommended as a prerequisite; however, a refresher of the important fundamentals is presented at the beginning of the training.

·         AC waveforms
·         AC phase relationships
·         Resistance in AC circuits
·         Capacitance in AC circuits
·         Power in AC circuits
2.            Semiconductor Fundamentals
·         Atomic review
·         Semiconductor conduction
·         Extrinsic semiconductors
·         Diodes
·         Transistors
·         Silicon controlled rectifiers
·         Logic review
·         Operational amplifiers
3.            AC Synchronous Generators
·         Voltage regulator function
·         Voltage regulator components
·         Voltage regulator operation
·         Auxiliary regulator functions
·         Voltage regulator troubleshooting
4.            Voltage Regulators/Exciters
·         Voltage regulator function
·         Voltage regulator components
·         Voltage regulator operation
·         Auxiliary regulator functions
·         Voltage regulator troubleshooting
5.            Generator Protection
·         Short circuit protection
·         Ground fault protection
·         Overload protection
·         Thermal protection
·         Over speed protection
·         Low field excitation or loss of field excitation protection
