摘    要:提出了电力线电磁干扰的评估方法,可以获得符合FCC标准的PLC功率限值。首先基于计算电磁学理论,建立PLC传输模型和电磁辐射模型,并对PLC的电磁辐射进行近场测试;然后根据测试结果调整PLC传输模型参数,使得PLC空间的电磁辐射计算值与测试值趋于一致。最后计算观察点处的电磁辐射。可用于评测PLC与室内短波无线电、超宽带无线通信等系统的电磁共存性,并制定功率限值标准,实现绿色电磁环境:

关 键 词:电力线通信  电磁干扰  电磁辐射评估

Abstract:The electromagnetic (EM) evaluation method for Power Line Communication (PLC) is presented, which could acquire the PLC power threshold that meets to FCC standard. First,the transmission model and EM radiation model of PLC are set up based on computational electromagnetics theory ; and the EM radiation of PLC is tested in near-field. Then, the EM parameters in PLC transmission model are adjusted to make the computed EM values fit to the test ones. At last, the EM radiation of the observe location is computed. This method can be used to evaluate the EM coexistence about PLC, inner shortwave radio and ultra wideband wireless system etc, and the power threshold standard could he set down to implement the green EM environment.
Keywords:power Line communication  electromagnetic interference  EM evaluation
