What is "Run of the river scheme"?

Question

Run of the river scheme is something related to hydroelectricity.I want to how energy is generated using this process?

Answer 1

"Run of River" is a method of converting the potential and kinetic energy of flowing water into electrical energy.

In any hydroelectric system E=Q x H where E is energy, Q is water flow and H is head. Conventional hydroelectric projects like the Bonneville Dam or the Three Gorges Dam depend on lots of Q, while ROR projects need lots of H.

The ideal ROR scenario has a high head water system, such as a creek or river in a high mountain cirque, where there is a large elevation difference between the intake of the penstock and the turbine. Instead of allowing the water to flow downhill along its natural course, a ROR hydroelectric system collects the water into a penstock (pipe), then the water runs through a turbine at some elevation below the intake (the head).

Both types of hydroelectric systems depend on "free energy" from rainfall and neither prodcue any greenhouse gases while in operation. The difference between ROR and a more conventional hydroelectric dam is that ROR does not have any water storage with large flooded areas behind a dam, so there is much less impact on the environment. The disadvantage of ROR is that the electrical output varies according to the water flow.

Answer 2

Sorry I don't know about this.May be it is related to hydroelectricity.
