Electric converter

I am assuming your generator is DC. Look up the term "inverter". That s the technology you need and they are ubiquitous. They are used to create an AC pseudo-sine wave output from a DC source. The most common use now has become wind generators, but they were originally designed for marine applications to run AC equipment from battery sources.

The problem with using capacitors (condensers) is that they tend to store very little energy for their size. They can store a lot of potential, but tend to give it up very quickly, so their usefulness as a storage medium is negligible. Lots of people are talking about "super capacitors" but practical usable ones have yet to hit the market. Just use batteries.

We really need to know what the electrical generation element is and roughly what the output voltage and electrical power (in either kW, KVA or Amps) will be? Is it using a DC (direct current) or an AC (alternating current) generator?

Also, are you trying to directly connect the wave generator to the national power grid (correct voltage and frequency) or are you bringing back the (raw) wave generated power to a central installation on land where the power can be further converted to the point where it can be connected the national power grid?

Different solutions exist for different applications, some of which may benefit from super capacitor storage (which only works on DC remember). Either way you will likely need some sort of inverter for the voltage conversion, a energy storage method, and a frequency conversion device to ensure 60Hz output.

More information is required.

Actually, the advice you have been given to use an "inverter" is not bad, as the technology has been developed into something much more reliable and efficient than it used to be.

Why not look into the possibility of using some mechanical means of regulating frequency; after all, the wave-powered generator is mostly mechanical. Automatic, mechanical speed regulation of a flywheel powered by wave motion is not as difficult as you might think, and a 60 Hz alternator running at the proper speed will solve the problem.

The inverter can be a possibility after "storing" the source electric energy, capacitors would only store energy for a minimum time, just enouthg for the inverter to send it to the grid already converted as 60 Hz. It can be a set of capacitors connected in parallel having a switching capacity so they reach the required voltage for the inverter to work.-

We would have a set of DC generators at the Sea Wave Generators sending this random frecuency to the grid, so it should be converted to 60Hz. Of course we would also have a voltage transformer to send the energy to the grid....

The first idea was to store the energy in as compressed air in a tank, but that involves more moving parts lowering our efficiency.-

I will search the wave for the flyweel idea, thks

Are there out ther any comertial devices for this?

Actually, if you're producing more than several thousand watts, inverters are not particularly feasible.

Since you're generating DC, you could run a motor-generator set, which are available commercially up to 1000's of kW. The DC motor will need fairly good regulation, but it's easier to synchronize with the grid.
