Hello

I'm a part time student currently studying an Electrical Engineering degree and my final year project is based on modelling a proposed on-shore power generation system using an electrical engineering software tool to analyse load flow, short circuit, voltage rise, protection etc. However, as my background is oil&gas and process plant, I'm lacking all the data to input into the model for 11kV overhead lines. Would anyone happen to have a table (or know where I could find one) providing typical values for resistance, capacitance, reactance susceptance B with zero,1,2 Sequence values etc?

Any help would be much appreciated.

Hopefully this will point you in the right direction. Two references

Try cable manufactuers datasheets for the electrical properties, you will need to know the length of the cable

http://www.aeicables.co.uk/

and

Electric Cables Handbook avalaible via the IET knovel ebooks, specifically chapter 10. This will give you a hand with Positive, Negative and Zero Sequence Impedance for cables.
