Information

This is a simple model of the turbine that give possibilities for simplified modelling of the turbine unit. The model can use a constant efficiency or varying efficiency from a lookup-table. This model does not include any information about rotational speed of the runner.

This model is based on the energy balance and a simple valve-like expression. The guide vane 'valve capacity' should be used for this valve-like expression and can either be specified directly by the user by specifying C_v or it will be calculated from the Nominal turbinenet head H_n and nominal flow rate Vdot_n.

The turbine efficiency is in per-unit values from 0 to 1, where 1 means that there are no losses in the turbine. The output mechanical power is defined as multiplication of the turbine efficiency and the total possible power:

turbine_pressure_drop * turbine_flow_rate

Besides hydraulic input and output, there are inputs as the control signal for the valve opening and also output as the turbine shaft power.
