SVC Design
(OP)
Does anybody know how to decide the number of branches in a SVC?
The question is to design a SVC using TSC and TCR for smooth control say around -100 to 400 mvar connected to a 345 kv bus via a transformer of suitable size. Kindly help! I really dont know where and how to start!
Also, how to design filter for the same and perform loss calculations?
Thanks!

Hint. Do you have a target PF envelope? (TPFE) If all else fails you can use a WAG solution.

The Req. control for voltage is 0.95 pu-1.05 pu..
Also filters for 5th and 7th harmonics are needed. Smooth control over -150 inductive to 400 capacitive with maximum switching of 150 mvar possible.
I know how to achieve smooth but there are multiple techniques.
Does anybody know a definite way of doing this?

The place where im stuck is the filter and whether the capacitor branches are acceptable.

1.Defining load profile
2.Harmonic analysis of the load
3.Harmonic Analysis of TCR part
ABB and some others have fixed harmonic portions according to application.

It is a big project and nothing you shall do without having any experience at all. Ask ABB, they have done hundreds and hundreds SVCs.
