66 KV EHVT SUB STATION
66 KV EHVT SUB STATION
(OP)
We are designing the 66 kv EHVT out door substation, & we shall wellcome for any guidance / improvements of the same.
Can any one direct us for the lay out drawing of the 66kv 10 mVA EHVT substation, with protective relays desired, & incorporating the flash over protections , clearances et...

RE: 66 KV EHVT SUB STATION
First of all you should have complete spec. of the substation equipment and ready for dispatch, which we call the electrical part. Then you need the data for all the lattice structure, which you can design and procure the angles or give data to the contractor to design and instal subject to the site conditions like wind loadings, siesmisity, ambient temperatures etc. This we call mechanical part.
Then you need design of Civil works like foundations for all structures.
Be careful, to prepare the data for grounding design, because this is the only part, nobody takes responsibility and in the end it comes under the head of the project manager. You need to have thorough design of the grounding before the shovel, pick or the bulldozer enters the site.
So layout is not a big deal in the substation construction.

Another approach would be to develop the basic design criteria and then go out for bids on a turnkey design/build contract - there are many international firms with appropriate experience to handle such a job.

Reference 1 can be considered since it has included many suitable References.
Some substation equipment manufacturers have good support including software that you may need for sizing and verification electric parameters to interface the grid and provide suitable parameters for load. Also, there are industry standards covering substations in reasonably good details.
