Power saving

Hi Mukesh

100 TPM - 1.6 TPS - is quite a load. Not so long ago I stopped next too one of these conveyors and thought about your problem.

Stop start operation seems to consume a lot of energy and improving the starting efficiency will surely save some energy.

I also thought that a variable speed drive will keep the energy down.

Have you considered (bigger) buffer stockpiling at both ends? This will even out the tempo and reduce start-stops. I realise that it may be costly.

The financial-economic balance will have to be calculated.

Out of curiosity:

Your terrain is it level, sloping or up and down?

What is the Max speed?

Max T in transit at any stage? (T/km)

Max and min. tempo required?

Total Kw?

Dear sir

Thanks for reply

Your terrain is it level, sloping or up and down? No (only 8 meter)

What is the Max speed? 4.5 m/s

Max T in transit at any stage? (T/km)

Max and min. tempo required?50( max) and 15 (min)

Total Kw?3100 KW

You can only save energy that is being wasted. First define where you think energy is being wasted in this application. If you cannot determine that, there will be no savings in ANY of those methods.

Hello,

You can also try to make an energy buffer and reduce the power peak from the grid.

At startup you always have an power peak, by shaving this peak, you can save a lot of energy, and money.

This can be achieved by using Boostcap® Ultra capacitors.

Store energy with a minimum amound of losses. The next step can be regenerativ braking, and store the energy when braking very quick, and re-use this energy by starting up.

I work on several projects, and believe me, there can be more energy saved than you think at this moment.

Can you please tell me what these small BOOSTCAPS (for a Voltage of 15V as I saw on the homepage) can do in a 3100kW-Sytem? Its no car-audio-application, I think you possibly mixed some dimensions ?

I'm sorry sir, but you are almost completely incorrect. Please do not post dangerous engineering principals in the forum, some people may read it, assume you know of what you speak and attempt to implement it, wasting time and money. Life is tough enough as it is, people do not need to go off chasing rainbows.

I pity the customers you have already worked for (if that is even true). they must have been extremely ignorant to fall for that load of garbage.
