Plant Process Model

The Generator And Electrical Systems Software Model

• The generator electrical simulation includes the following components:

1. GeneratorExciter and pilot exciter
2. 22 KV breaker and the 400KV breaker (Functional simulation only)
3. Automatic voltage regulator
4. Generator and turbine rotary dynamics
5. Generator auxiliaries (Functional simulation only)

• The generator model is capable of the entire range of operation, such as run-up, synchronization, load rejection and load changes as well as frequency and voltage interference. The model includes the generator and unit transformers and all their auxiliaries. The excitation system is modeled and includes the ability to make the generator unstable if excitation is too low. The major parameters that are simulated include but are not limited to:

1. Angular speed,RPM and mechanical damping,
2. Produced EMF,
3. Active and reactive power,
4. Both manual & automatic voltage regulation and
5. The generator’s power factor as governed by the generator’s voltage and the excitation system.
