摘要
高压直流换流站中的换流阀在运行过程中会产生高强度电磁噪声,在30-500 kHz频段对邻近的载波通讯系统形成潜在干扰.为预测该电磁噪声水平,以高肇直流系统载波频段噪声水平的实测结果为基础,建立了符合换流站实际运行参数和一次设备高频参数的仿真模型,通过对肇庆换流站的电磁噪声实测值与仿真计算结果的比较证明了模型的有效性.
High level electromagnetic noise is produced in HVDC converter station,which could cause harmful interference with carrier systems in the frequency range of 30 to 500 kHz.Based on the noise measurement results of Gaozhao HVDC system,a simulation model has been established to evaluate the electromagnetic noise,which accords with the converter station function parameters and the primary equipment's high frequency parameter.Comparison between calculation and measurement values for Zhaoqing converter station is given to illustrate the validity of the model.
