摘　　要：为了研究直流换流站换流阀在可控硅整流器导通或关断瞬间所产生的高频电磁波可能对换流站周围的无线电接收设备造成的干扰,文章利用以频域离散化方式得到每个阀片在频域内的等效阻抗,建立了单相换流阀塔的辐射模型;搭建了单相阀塔缩比模型以进行实验测量;通过将实验测量数据与基于所建立的辐射模型仿真数据的比较,初步验证了单相换流阀塔辐射模型的合理性。As the closing and opening of thyristor rectifiers of the converter valves in DC converter stations could produce high frequency electromagnetic wave,the radio receiving equipment around the station may be interfered by the operations of the rectifier.To analyze this disturbance,this paper sets up an electromagnetic radiation model of the single-phase valve tower with equivalent impedances calculated by frequency domain discretization of every thyristor,and builds a scaled model of single-phase valve tower to make experimental measurements.In comparison of the measurements and the simulation data based on the model,its rationality is verified somehow.
