Energy Solution

 

 

The AC grid without the generator connected

 

The same AC grid when the generator is running at about 60RPM

 

A Sample Off-The-Shelves System

 

Testing station of a bare bone system.

 

. The beige/white 3 phase motor with a VFD (blue) to drive the small generator.

 

. The little white cube on top of the VFD is a net metering meter. However a combination of: scope + Amp meter + volt meter gives real-time and more accurate reading.

 

. The shoe appears on the pictures is on a safety switch. One has to step-on in order to turn the power ON

A breakthrough discovery, a 'dream comes true', an RPM independent, grid tie induction generator since the 19th Century

Can I manually operate without a controller?  --Yes.

The Generator will get itself burned - smoke==> if

      (a) There is not enough torque to turn it to the minimum RPM (20RPM?)

      (b) Once it's turn on, because it now generates the electricity it will slow your generator down then if too slow below the minimum RPM? - It get burned

      (c) There is not enough torque to keep more than minimum RPM (20RPM?)

As you see? If you can afford to turn on when it turns fast enough and turn OFF when it is too slow then you can get by with it.

A simple controller is handy to monitor your turbine RPM to do just as above.

There are three options that you can do.

     (a) DIY - by off-the-shelve components. (It's expensive though!)

     (b) Inside those above components are just some resistors + capacitor working with the LM555, LM556 timers. You actually can build one for a fraction of that money. There is a lot of information on the LM555 on the net. If you look at the logic at (a) above, a simple circuit of 4 of the LM555 or 2 of the LM556 plus one relay can do the job.

     (c) Even More sophisticate developer can build as simple project such as a PIC. Or even over kill by using a PLC or even an FPGA.

     (d) Of course you can buy a ready made one. either based on the (b) or the (c) above.

Of course using this simple controller one will indeed encounter some limitations.

The output of your generator is only dictated by the size of your generator and the force to turn it at that speed.

Here one scenario.

Assuming that you have a water turbine that have a  lot of torque; your setup is to generate 50% the capacity of the generator at 30RPM. But even at that force it does not slow down the generator much it means that there are more energy to harness. You can use a bigger generator or change your setup to turn the generator more faster.

Here other scenario.

Assuming that your wind turbine have the setup to capture at the minimum 10% of the generator if below that then you have to turn off. You are wasting the energy that you can harness.

One more scenario.

When you wind turn too fast (strong wind) to make the generator turn more then 10% of its synchronous speed. the capacity of the generator goes down. With this simple controller you will have no other choice but waist the energy into turning the turbine faster instead of utilize it to generate much needed electricity
