Abstract
- Wideband frequency electromagnetic (EM) noise generated during the turn-ON and turn-OFF processes of thyristor valves in converter stations is conducted along the primary circuitry, and may interfere with secondary systems. The EM interference (EMI) problem in a ±800 kV ultra-HVdc converter station is an important issue that should be studied carefully in the design stage. A method to analyze the conducted EM disturbance (EMD) based on time-domain wideband circuit simulation is proposed here, which is verified through the field test results of a ±500 kV converter station. Models of major equipment are described. The EMD levels of a ±800 kV converter station, which is currently being planned and built in China, are calculated, and compared with those of a ±500 kV converter station. [ABSTRACT FROM AUTHOR]
