Abstract

The electromagnetic interference (EMI) from the valve hall as an important consideration in the design of high voltage direct current (HVDC) converter stations is analyzed by electromagnetic field numerical method and measurements. By using moment method, the EMI filed strength level as well as radio interference level (RIL) of the valve hall during the normal operation are computed after an antenna model is built for the valve tower. According to the character of EMI obtained, the practical shielding measures for valve hall are discussed to satisfy the relative standards. The test results for the±500 kV converter station show that both the numerical method and shielding technique used in this paper are practical.

Key words： electromagnetic interference (EMI); valve hall; high voltage direct current (HVDC); converter station; shielding
