A turbine is provided for a hydroelectric power station. The turbine has a rotor with a plurality of blades, with the rotor being arranged in front of a guide apparatus (in the flow direction). The pitch angle of the blades on the rotor is designed to be variable. Since the rotor is arranged in front of the guide apparatus (in the flow direction), the flow strikes the rotor first and does not strike the guide apparatus until after this, thus resulting in optimum flow conditions for the rotor.
