Idea to save output power

[anderson_88]

Hi all,



I am thinking to save the output power from 115V AC 3 phase generator and 28 V DC generator while testing.

Every day we will be testing the above generators for more than 3 hrs. I would like to get any idea of how to save the output power and use any thing useful out of it



Any suggestion or ideaS?

thanks

Convert the electrical energy into mechanical energy then store the mechanical energy that can be released later.
1) Let the generator drive an electric water pump.
2) Pump the water to a reservoir up high.
3) When you need to use the stored energy then let the water run down to a waterwheel that drives a generator.

Use the energy from the generators to power up something. Resistors to heat up something, lights...something.

Or use an inverter like the ones used by wind generators to feed back the energy back to the mains.

Hi,

What power are you talking about? milliwatts or megawatts?
What energy are you talking about? mWs or MWh?

**********
Assuming it is in the range of 1kW.
x 3 hours per day = 3kWh per day
x 250 working days = 750 kWh per year.
x 0.25 Euro per kWh = about 187 Euro per year.

-> You can use it for heating water

Are the generators driven by elctromotors? Then you could control the motors with an inverter.
Within the inverter there usually is a DC stage with capacitors. Feed you energy back into this DC stage and the inverter needs less power from mains.
Mind to protect the DC stage from overvoltage. (only necessary immediatly after switching off the motor and the remaining rotating energy is stored back to the DC stage)

Considering energy cost to consumers starts around $10/KW-h and a big chunk of that is distribution cost. To make something useful depends on your ability to store it or import an energy consuming device that can be useful.

I presume this is diesel engine driven.

How about contact recycling dealer and ask if they have any portable processes with free power avail.? plastic or metal melting furnaces....
