Power House Micro Hydro 20 KW Pumps as Turbine Motor as Generator

This Micro Hydro installation uses Pumps as Turbines and 3 phase Motors as single phase Generators. (yes you can!) There is 210 feet of head (92 PSI) and 550 ft of 8 inch welded steel penstock. We can draw 2500 gal /minute and still maintain about 85 PSI. Currently operating Autonomously (off the Grid) and supplying 4 houses. Bring your water jet pack and let's see you fly on water power!

How it's maintain constant frequency?

[Honders]

@HungryGreeny ,

It has a frequency feedback loop. If frequency drifts up the valve closes some, if frequency goes down the water valve is opened very slowly.

[HungryGreeny]

@Honders So, why there is dump load controller? I thought destination of dump load is to provide constant load on the generator, and thereby maintain constant rpm, and constant frequency. Where is my misunderstanding?

[Honders]

@HungryGreeny Yes, the load controllers act more rapidly to keep the voltage in check. The frequency feedback loop is slower acting but keeps the long term stability of the frequency in check. Grid connected generators are automatically stabilized by the grid and don't need these controls.

[Honders]

@HungryGreeny , The grid is like a freight train, my little generator is like a person pushing on the back. The train (grid) speed (voltage/frequency) will be the same no matter if I push or not, or whether it is loaded down with 100 cars or 110 cars.

Sorry, no such thing as a perpetual motion machine. But check out LENR CANR on google. Pons and Fleischman discovered it in 1989, now Rossi and Focardi appear to have a practical working device!

@bashiryu

I have water coming from upstream. The nuclear fission in the sun put it there (rain). I'm just extracting a small % of the energy that the sun put into the water by raising it up.

If I were to try to pump it back up I would lose about half the energy in the water at each spin around the loop. No such thing as perpetual motion but there are plenty of real & possible ways to harvest energy, so don't stop dreaming, but concentrate on the possible and study physics.

Looks like a well planned operation. How much energy is it producing?

[HungryGreeny]

@Honders Thanx for your answers!

[HungryGreeny]

@Honders Hm, then i have another question - why grid connected generators automatically stabilized? Grid also don't have constant load isn't it?

[MrJgodwin]

How many volts were you pumping out ?

[douro20]

How much power are you generating?
