Theoretically optimal location of a distribution substation

Former Community Member

Hello, 
I have the following problem with the preliminary design stage of a residential area:

The software I use can calculate a theoretically optimal location of a distribution substation for low-voltage networks. This place is calculated as a "center of power demand" or "center of gravity" of electrical consumers.

If the substation locates in this optimal place, we can design 0.4kV distribution feeders with a minimum length and power losses in low-voltage feeders are minimal. 

I understand it’s almost impossible to put it exactly there, and I consider some sites nearby. But the architect believes that this is unacceptable in terms of landscape design and wants to place the substation in a far corner.

Who should be the arbiter in this situation?  DNO representative takes a neutral position.  Local authorities are completely on architect side, they do not care that long power cables will heat the atmosphere for many years to come.

    Hi Alex    I see that you are considering this in a non-UK country from the 10kV/400V substation. 


    Yes, we are doing this project in one of the EU countries. This is a real project, but I would like to consider the situation as hypothetical.

    OMS is quite right, the civils and jointing cost will be much more than the cable, so it is not worthwhile to comprimise cable costs.

    I wanted to compare the cost of electricity losses in low-voltage feeders but not the cost of cables. Over 30-40 years of operation there will be a large amount of costs for power losses.  Of course, the end consumer pays for everything. But if the DNO would get shorter cables with less power losses, then they could take the saved money to himself.
