Single phase and three phase induction / synchronous motors can be used to generate single and three phase electricity to provide low cost power generation in remote locations of the world.

Micro-Hydro is a valuable source of power generation in rural industries and remote village electrification schemes.

What typical applications can Micro-Hydro be utilized for?

Typically Micro-Hydro power can be used for projects demanding power in the range of 200W up to 30KW when using a water pump as a generator.

At the outlet from the PAT, it is advisable to use an expanding pipe, known as a draft tube, or a reducer in reverse to increase the diameter of the pipe where it discharges into the outlet channel. The water in the outlet channel is at atmospheric pressure, and therefore the channel must be large enough and with a great enough slope to take away the full flow from the PAT. If a pipe is used to return the water from the outlet channel to the stream, this pipe must be at least twice the diameter of the penstock to take the water away without causing the outlet channel to overflow.

The science is pretty simple. Take a water pump and run a head of water through it and providing you get the flow rate and head correct then the pump will generate electricity. Some modifications may be required to let the motor produce AC electricity but in theory it can be done and is a simple and proven method of low cost power generation.
