Design Parameter for 33kV Overhead Line
Design Parameter for 33kV Overhead Line
(OP)
Im doing a self study kind of project to try to educate my self with Power distribution as im a Communications Electrical Engineer and not a Power Electrical Engineer.
I have 2*150MVA 220/33KV transformers, these transformers will be feeding 165*230KW Water pumps using 165*300KVA 33/0.4KV pole mounted transformers in a piece of land 40*10Km. The total length of the ring circuit will be 160Km long.
what kind of parameters should I take into consideration? like voltage drop, total load , etc..

RE: Design Parameter for 33kV Overhead Line
Performance criteria: do you need a radial or looped network?
Can you influence the 220/33 kV sub location? This will have an impact on voltage drop, currents etc.
Protection philosophy: fuse burning or fuse saving?
Then build yourself a digital model, then run load flow, voltage drop, short-circuit, motor starting, cold load pickup analysis.
Optimize your design considering losses, reliability and future load increase.
Have fun!

I guess there is a lot I need to learn. is there a good book that you would recommend where I can read up on those parameters? also what kind of software would be able to emulate this kind of model?
RE: Design Parameter for 33kV Overhead Line
You should be able to find something on the web.
There are a number of software available: CYMDIST, SKM, ETAP, EasyPower, Milsoft.
Some of them have free limited time demo. Plan your network, find your equipment data and then get a demo copy and run your simulations.
You will then be able to run multiple configurations and check resulting overall performances.

i have already started looking for some books and will decide to buy after I review them and get a better idea of what I want to spend my money on :)
