6. Governing Equations

(no equations)

7. Remarks for Usage

All records (PQ diagrams and Heat input matrixes) included in this package are included with the intention of illustrating the modelling concept.

However, users are encouraged to create their own records based on the plants and scenarios that they want to simulate.

8. Validation

(no validation or testing necessary)

9. References

These characteristics are based on an estimation made with stationary simulations of a power plant simulation program.
