| 摘 要： | 为了抑制直流输电系统中因换流阀导通和关断时电压突变在交直流线路上产生的大量电力线载波(PLC)噪声,并将其降到规定的限制标准,减少对PLC通信系统产生干扰,在PLC噪声滤波器设计中应用了电磁兼容(EMI)滤波器的设计原理。通过与EMI滤波器进行对比,得出PLC噪声滤波器的特点并根据噪声源和负载不同的阻抗特性,给出了4种适用的PLC噪声滤波器的网络拓扑,并详细说明了各种结构中主参数和调谐参数的确定方法。最后用Matlab/Simulink作为仿真平台,以贵广二回直流输电系统深圳换流站交流侧PLC噪声滤波器设计为例,证明所提出的设计方法是可行的。

| Abstract: | Power-line carrier (PLC) interference noise is caused by the voltage breakdown in converter valves during the firing processes. The noise propagates along DC and AC lines,interfering with the PLC communication system. In order to suppress the noise to meet the limit requirement,PLC filters are installed. From the perspective of frequency domain,the principle of PLC noise filter is similar to the EMI filter. We applied the EMI filter design principle to the PLC noise filter,summarized the characteristics of ... |
