Description
Summary:Due to the wide application of new technologies, such as wind power, photovoltaic power, distributed generation, and smart grid, the new high-voltage direct current transmission technology based on voltage source converter (VSC-HVdc) has gained great advantages over the traditional one. This paper presents a novel method to analyze the radiated electromagnetic disturbance (EMD) of the VSC-HVdc converter system by combining the circuit theory with the electromagnetic theory, considering its structure together with the operational states. The method combines method of moments (MOM) with antenna theory, based on the experimental platform of the VSC-HVdc converter system located in North China Electric Power University. The mechanism of the radiated EMD generated by converter valve is described, and the source of disturbance is measured by a high-resolution probe and a high-performance oscilloscope. The antenna model of the VSC-HVdc converter system is developed, and by applying electric dipole theory, the radiated EMD produced by the three-phase two-level VSC-HVdc converter system is calculated in FEKO, which can conduct MOM simulation. Finally, the proposed method is verified by the comparison between the calculated data and the measured data, and the influencing factors of EMD are discussed.
