Power System Static Var Compensator SVC for Power Quality

Go the the simulator yourself: www.ecsp.ch. This is a cool video about the basics of static var compensators SVC. You can find more videos on: / @georgschett801

hello, thanks for the explanation, it really helped me, I hope you are always healthy

Thats a very good explanation

hi thanks for sharing. I have doubts.
1. The over voltage at load side is it because of Ferranti effect.. the grid wire to ground capacitance build up causing it?
2. The undervoltage inductance is it because of load side majority of inductive loads ? is that the only reason or is there any more reason?
3. Third could you share your knowledge on how to design 3 rd and 5 th hormonic filter you are designing ? Mathematical calculations or any insights?
Thanks

Thanks for your feedback and for your interest.
1. The over voltage at the load side is because of the Ferranti effect or because of any other capacitance which causes a voltage increase.
2. The under voltage is due to any resistive or reactive load connected to the circuit. The circuit needs to be inductive however (lines, transformers or generation for example).
3. There is lots of publications on the internet about filter design. I just took the frequency domain simulation of ecsp and adjusted the filter to meet the third and fifth harmonics. In reality you may add additional filters filter for higher harmonics.
Best regards

Hello thanks for good explanation. Just thinking, adding inductors in parallel should decrease inductance. If you have over voltage because of too much capacitance, then shouldn't the inductor be added in series? Cheers?

[@georgschett801]

You have to add inductors in parallel. Just as a very simple model: Many inductors in parallel would bring you closer to a short circuit where the voltage would be zero. Many inductors in series however would bring you closer to an open circuit which would have no effect on the over-voltage anymore.
