The AC voltage measuring system is one of the most importance paths for electromagnetic interference propagation in HVDC converter station. In this paper, a wide-band simulation model is proposed to analyze the electromagnetic interference propagation in it. Experimental study is also carried out to obtain the EMI noise level in measuring system. Comparing with experimental results, the calculation...
The power line carrier (PLC) system used in HVDC converter station is connected directly to the primary system via coupling devices, and may be interfered by the electromagnetic noise produced by valves or switch operation procedure. In this paper, the EM noise in PLC system of plusmn500-kV HVDC converter station is measured in the steady state. The transient disturbance during the switch operation...
