Simulation analysis on radiated EMI from the DC buses in ±500-kV HVDC converter stations

The wide-band frequency EM noise is generated during the processes of firing and turn-off of thyristor valves in converter stations. It will be conducted along the primary circuitry into HV devices located in the DC yard, and the radiated EM noise is generated because of the antenna effect. The noise may interfere with the systems in or around the DC yard… CONTINUE READING
