I'm doing some research into capturing a large amount of energy over a short period of time. The energy will be stored in supercapacitors but I'm finding it hard to find information on how a generator would cope with this.
My project investigates the feasibility of using a regenerative braking system on an aircraft and I'm looking for a rough idea of what the limits are of capturing a very high current with a generator. The reason a high current will be required is to capture as much energy as possible over a short period of time. The amount of available kinetic energy I have calculated after losses is around 460MJ or 129kWH.
I have found some examples online such as a 200KW generator which is capable of dealing with 300V at 400 amps. If the time available to capture the energy is 60 seconds, would this mean that 120kW x 1/60 = 2kWh could be captured in this time? This is nowhere near enough to prove the concept of what I'm looking at if so
Sorry if I am confusing KWh with joules here, any input pointing me in the right direction would be much appreciated
