“…From 1970 to 1990, many scholars carried out theoretical calculations and measured analyses of electromagnetic disturbances in HVDC converter stations (Annestrand, 1972;Sarma and Gilsig, 1973;DeVore et al, 1988;Caldecott et al, 1990). The factors affecting radio interference levels were discussed and interference in the frequency range of 0.1-10 MHz was analyzed (Annestrand, 1972).…”

“…For the wide use of high voltage direct current (HVDC) projects, the electromagnetic interference (EMI) of HVDC converter station has been paid more attention [1][2][3] recently. Especially for China, which has the largest quantity of HVDC projects in the world and is building the first extra high voltage direct current (EHVDC) (AE800 kV) projects in the world, the research of EMI of HVDC projects is significant.…”

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 AE500 kV converter station show that both the numerical method and shielding technique used in this paper are practical.

Abstnct HVDC converter station operations generate radio frequency (RF) electromagnetic (EM) noise which could interfere with adjacent communication and computer equipment, and carrier system operations. A generic RAdio Frequency Computer Analysis Rogram (RAFCAP) for calculating the EM noise generated by valve ignition of a converter station has been developed as part of a larger project. The program calculates RF voltages, currents, complex power, ground level electric field strength and magnetic flux density in and around an HVDC converter station. The program requires the converter station network to be represented by frequency dependent impedance functions. Comparisons of calculated and measured values are given for an actual HVDC station to illustrate the validity of the program. RAFCAP is designed to be used by engineers for the purpose of calculating the RF noise produced by the igniting of HVDC converter valves.
