hi guys
i appriciate to let me know about DC side filter of a HVDC transmition line connected to a 50HZ AC system from one side (e.g. rectifire side) and to a 60HZ AC system from the other side(e.g inverter side)
as u know, even harmonics are considered for DC side filters,imagining a 12 pulse csc converter, so it means using a "12*50HZ" filter at one side and using a "12*60HZ" filter at the other side?
Dear Saber,
What do you judge in your question is correct. It is so that the filters are designed to suppress the harmonics starting with the first harmonic after the fundamental. If you designed the filters at both sides at 50 Hz fundamental frequency in both sides it will work well at the 60Hz side as it will cuts off at an mealier frequency. But you can not use the 60 Hz side filter in both sides.
Best wishes
