This master thesis was made to validate hydropower models of a turbine governor,

Kaplan turbine and a Francis turbine in the power system simulator ARISTO at

Svenska Kraftnät. The validation was made in three steps. The first step was to make

sure the models was implement correctly in the simulator. The second was to

compare the simulation results from the Kaplan turbine model to data from a real

hydropower plant. The comparison was made to see how the models could generate

simulation result that was similar to the reference power station. The third was to

validate in which way the Francis turbine model influenced the simulation result from

a small power system. Data from the Swedish black start test system was available

and used as reference data. The main question for step three was if the simulation

result got better and more like reference data if the Francis turbine model was used.

The result showed that the models was correct implemented in ARISTO and that the

models can generate simulation result that was similar to reference data if the correct

parameters was collected from individual power plants. The torque tables for the

turbines models and the parameters for the PID-controller in the turbine governor

had greater impact on the simulation results then other parameter in the models.

Key word: turbine, hydropower models, power system simulation
