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.

    Personally speaking, put in a few 3 phase feeders from the substation and "T"off for each property - two or 3 circuits would deal with the whole lot at minimal cost and optimum size to mitigate the I2R loss. 

    Power supply is designed on the basis of several 3-phase loop-feeders (underground) from the substation. If we compare the lengths of these loops for both variants, they any way will be much shorter in the variant with an optimal location of the substation.

    Street lighting (including a small park and a playground) will be designed by separate lines from a separate cabinet near the substation
