Abstract
There is provided a turbine for a hydroelectric power installation. 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 of the rotor is adapted to be variable. As the rotor is arranged in front of the guide apparatus (in the flow direction) the flow meets the rotor first and only thereafter meets the guide apparatus, thus affording optimum flow conditions for the rotor.
Claims9
A turbine for a hydroelectric power installation for generating electrical energy comprising:
- a rotor having a plurality of turbine blades;
- a guide apparatus having a plurality of support blades which are arranged after the rotor in the through-flow direction and which serve as a support apparatus of the turbine;
- wherein the pitch angle of the turbine blades of the rotor is adapted to be variable;
- and
- wherein the turbine is in the form of an upstream rotor turbine so that the turbine blades have an afflux flow which is substantially undisturbed by the turbine in the through-flow direction.
9 A hydroelectric power installation according to claim 7 further comprising a rectifier for rectifying the electrical output voltage of the generator and an inverter which is coupled to the rectifier and to a network connection, wherein the inverter serves to deliver electrical power from the generator to the network at a frequency which is required by the network.
